in r, how index list of values 1 r column based on specified list of values column? i know how select , modify specific row numbers, e.g.: > foo=data.frame(a=100*1:5,b=letters[5:1]) > foo b 1 100 e 2 200 d 3 300 c 4 400 b 5 500 > foo$a[c(1,3,5)]= foo$a[c(1,3,5)] + c(3,2,1) > foo b 1 103 e 2 200 d 3 302 c 4 400 b 5 501 but if instead want select , modify rows 'b' values "a", "e", , "c"? thought which might correct tool, best i've been able come is: > foo$a[which(is.element(foo$b,c("a","e","c")))] [1] 103 302 501 at point i'm stuck, because while i've selected correct rows, aren't in right order can't modify them individually. removing is.element , use %in% solution if don't care matching order [edit] - can remove which foo$a[foo$b %in% c("a","e", "c")] another possibility use match provide indices of each eleme

it's well known creating nsdateformatters ' expensive ' even apple's data formatting guide (updated 2014-02) states: creating date formatter not cheap operation. if use formatter frequently, typically more efficient cache single instance create , dispose of multiple instances. 1 approach use static variable. but doc seems not date swift , can't find in latest nsdateformatter class reference caching formatter can assume it's expensive swift objective-c. a lot of sources suggest caching formatter inside class using it, example controller or view. i wondering if handy or 'cheaper' add singleton class project store datepicker you're assured it's never necessary create again. used everywhere in app. create several shared instances containing multiple datepickers. example 1 datepicker displaying dates , 1 time notation: class dateformattermanager { var formatter = nsdateformatter() class var dateformatmanager : dateform

some businesses track events in time "hour ending". each hour of day represented ordinal number: 1…24 utc 1…23, 1…24, , 1…25 time zones one-hour daylight saving time (dst) adjustment. so first hour of day, midnight 01:00 hour ending 01 . to me, seems silly way track time. more sensible using time-of-day half-open approach, [) , beginning inclusive, , ending exclusive. so: 2014-12-05t01:00:00.000 mark hour ending 01 2014-12-06t00:00:00.000 (midnight) mark hour ending 24 . indeed, want store in database ( postgres ), timestamp time zone value converted date & ordinal hour number. question is: given date , ordinal "hour ending" number (1…23/24/25 locality 1-hour dst), how convert date-time value? i'm familiar joda-time , java.time . either of them offer way convert? if not, kind of algorithm handles both ordinal number conversion , dst? or should not fight this, , store local date string suffix of ordinal hour number?

i relatively new r, , i'm doing dna sequence analysis. wanted know how table function return 0 if there no n's in sequence. instead of returning 0 returns subscript out of bounds. if statement thought there might simple way fix this? help! library(seqinr) firstset<-read.fasta("nc_000912.fna") seqfirstset<-firstset[[1]] length(seqfirstset) count(seqfirstset,1) count(seqfirstset,2) seqtable<-table(seqfirstset) seqtable[["g"]] seqtable[["n"]] if data factor appropriate levels, you'll have no problem: > x <- factor(letters[1:3]) > y <- factor(letters[1:3], levels = letters) > table(x) x b c 1 1 1 > table(y) y b c d e f g h j k l m n o p q r s t u v w x y z 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 > table(x)[["g"]] error in table(x)[["g"]] : subscript out of bounds > table(y)[["g"]] [1] 0 just set levels !

i've been pondering on around 3-4 hours , can't wrap head around how it. i've been looking @ this feed , trying replicate wordpress blog i'm working on, i've looked around numerous jquery plugins none seem keep them in rows - appreciated. the problem having feed on link above has lovely , nice laid out feed, it's not cascading pinterest, keen eye might spot each row aligned , start @ same position , end @ same position images variable heights. tl;dr wanting feed similar link supplied. static row height variable image height inside row. any great. the best way make table. <table> <tr> //a table row <td>content</td> <td>content</td> <td>content</td> </tr> </table> then css: table { position:relative; table-layout:fixed; width:100%; margin:1em auto 1em auto; } td { border-color:transparent; width:20%; height:450px;

i have question how use ng-switch inside ng-repeat , use scope switch-on ? example : <div ng-repeat="item in submenu"> <div class="animate-switch" ng-switch-when="{{item.filter}}"> <div class="navbar navbar-default navbar-static-top {{item.filter}}"> <div class="navbar-collapse collapse" id="navbar-{{item.filter}}"> <ul class="nav navbar-nav subnav"> <li ng-repeat="subitem in item.sub" class="items" > <a ng-href="{{subitem.link}}" class="{{selected }}" ng-click="selectfiltersub(subitem.filter)">{{item.name}}</a> </li> </ul> </div> </div> </div>

how create function takes list alternating math symbols (plus, minus) , integers return result. example, 4, '+', 5, '-', 1 should return 8. i'll give 1 liner. if homework, teacher's going raise eyebrow's @ this. given words = [4, '+', 5, '-', 1] then result = sum(digit * (-1 if sign == '-' else 1) digit, sign in zip(words[0::2], ['+'] + words[1::2])) what we're leveraging here said '+' , '-' operands. type of number sentence can rewritten (+4) + (+5) + (-1) . in other words, view +/- sign indicator, , sum them all. so decomposing above... # extract slice digits digits = words[0::2] # --> [4, 5, 1] # extract slice signs signs = words[1::2] # --> ['+', '-'] # our signs needs have same size digits, there's implicit '+' preceding first digit signs = ['+'] + signs # --> ['+', '+', '-'] # use if else , list comprehensio

i symfony/doctrine duplicate id in 2 different field every time record created. possible in 1 shot (i use stragegy="auto") ? if yes how can this? for instence entity category have 2 attribut id (auto). on named id, other idbis. (in exemple work on entity contains parent , children records, have idparent link children categories parent category) if record parent category, id , idbis same integer: => id=2, idbis=2, idparent = null if record child category (let parent category id=2) then: => id=3, idparent=2, idcategory1=2 that great because then retrieve categories (parent , children) linked category id 2. you should take nested set structures. it's made retrieve sub elements in simple query using bounds. otherwise can creating trigger on insert/update.

im making simple game , have started making each menu. there 3 menus in row - main menu - playher select menu - gamemode menu problem facing atm adding delay between touches. code have uses sprites buttons , detects whether touch point within bounding rectangle. like so: if(gdx.input.istouched()){ cam.unproject(playermenutp.set(gdx.input.getx(), gdx.input.gety(), 0)); if(sprites[1].getboundingrectangle().contains(playermenutp.x, playermenutp.y)){ game.changescreen(2); }} this works first menu since buttons in exact same position on each menu if hold finger on screen skips through menus. i don't know how modify wait until previous touch no longer occurring continue scan one. any appreciated. thanks i suggest use scene2d ui related stuff, it's not hard implement or learn, , easy mantain. anyway if want keep going in way, can this: make screens implement inputprocessor. se

i trying convert program delphi 2010 delphi xe7 (32 bit/windows vcl). code used work in d2010 automated excel via late binding ole gives exception "unable set window state property of application class" in delphi xe7, when app maximized or minimized. i getting constants xlmaximized , xlminimized excelxp unit has these constants: xlmaximized = $ffffefd7; xlminimized = $ffffefd4; however, if use simple constant values -4137 , -4140 program work ok. realize must doing simple wrong. below sample code illustrates problem. tested , works in delphi 2010, not in delphi xe7. suppose must how constants handled in newer versions(?) can point me in right direction? in advance! //xla global variable of type olevariant; //program uses comobj , excelxp unit //this proc runs or connects excel procedure tform3.runexcelclick(sender: tobject); begin try xla := getactiveoleobject('excel.application'); except try xla := createoleobject('excel

i noticed today ctrl-r, ctrl-t on highlighted test method in gui not debug test wrote when looks like: [testmethod] public async void test() { await asyncmethod(); } the project builds, test doesn't run. there no fail message or error message found anyplace. if remove async keyword, works fine. what's this? in code, i'm awaiting asynchronous call. don't see why test runner couldn't deal it. edit: after looking @ tests output, message this: uta007: method blah defined in class blah not have correct signature. test method marked [testmethod] attribute must non-static, public, return-type void , should not take parameter. example: public void test.class1.test(). additionally, return-type must task if running async unit tests. example: public async task test.class1.test2() ========== discover test finished: 3 found (0:00:00.1367583) ========== i don't @ it, visual studio wants show me build output , errors more often.
