scenario: consider following abstract class measurementtype , subtypes acceleration , density : public abstract class measurementtype { protected string name; protected string[] units; public measurementtype() {} public measurementtype(string name) { this.name = name; } protected void setname(string name) { this.name = name; } protected string getname() { return name; } protected void setunits(string[] values) { this.units = values; } } public class acceleration extends measurementtype { private string name; public acceleration () { super(); } public acceleration(string name) { super(); } } public class density extends measurementtype { private string name; public density() { super(); } public density(string name) { super(); } } question: what need subtypes since there isn't in classes differentiates them apart enough (at least in implementations) give them right exist own entities,...

i'm using dosnow- package parallelizing tasks, differ in length. when 1 thread finished, want some information generated old threads passed next thread start next thread immediatly (loadbalancing in clusterapplylb) it works in singlethreaded (see makeclust( spec = 1 )) #register snow , dosnow require(dosnow) #change spec 4 or more, see problem registerdosnow(cl <- makecluster(spec=1,type="sock",outfile="")) numbersprocessed <- c() # init processed vector x <- foreach(i = 1:10,.export=numbersprocessed) %dopar% { #do working stuff cat(format(sys.time(), "%x"),": ","starting",i,"(numbers processed far:",numbersprocessed, ")\n") sys.sleep(time=i) #appends number general vector numbersprocessed <- append(numbersprocessed,i) cat(format(sys.time(), "%x"),": ","ending",i,"\n") cat("--------------------\n") } #en...

when 'every 3rd iteration' mean 'every 3rd iteration... starting number 4' if every 3rd, target appropriate iterations so: <?php if ($count % 3 == 0) : ?> bear in mind i've set $count 1 beforehand but iterations need start 4th, 7th, 10th etc. does know how can acheive this? can simple if statement 1 above? unfortunately don't think for loop possible wordpress loop i'm dealing with your thoughts using modulus operator sound, need expand scope of logic surrounding it: you want every third iteration after initial 4 have passed. begin logic after first 4: if ($count > 4) then, want each 3 after that. counter includes initial 4 iterations didn't want include, remove counter , check if current iteration multiple of 3: if (($count - 4) % 3 === 0) this should give you're looking for. if ($count > 4) { if (($count - 4) % 3 === 0) { ... } } you can put 1 line: if ($count > 4 &...

i have lattice bar chart multiple panels , add sum of each bar on top of bars (e.g. (70) on top of first bar on top left, (20) on second one, (150) on third 1 etc.). there similar question here not find way adapt code plot. unlike in example, add 'total sum' of men , women on top of each bar vertical bar. not label them separately using ltext shown here . suggestion, using ltext or other way, helpful. civ1<-c("single","single","marr","marr","single","single","marr","marr","single","single","marr","marr","single","single","marr","marr") sex<-rep(c("women","men"),8) year<-rep(c(rep(1990,4),rep(2000,4)),2) type1<-c(rep("traditional",8),rep("dual-earner",8)) earn1<-c(seq(10, 160, = 10)) df<-as.data.frame(cbind(civ1,sex,year,type1,earn1)) df$earn1<-...

is profitable test "core" features such scopes , sorting? have several tests test functionality similar what's below. seems me it's testing rails core features (scopes , sorting), well-tested already. i know may seem "opinion" question, i'm trying find out if knows miss if assume scopes/sorting tested , not valuable developers test. my thoughts if scopes/sorting "broken", there's nothing can if rails core code broken refuse touch core code without very, reason (makes updating later on nightmare...). i feel "safe" more tests if these tests aren't providing value, taking space , time on test suite. # user.rb model class user < activerecord::base scope :alphabetical, -> { order("upper(first_name), upper(last_name)") } end # user_spec.rb spec context "scopes" describe ".alphabetical" "sorts first_name, last_name (a z)" user_one = create(:user, first_name: ...

i have made poisson regression , visualised model: library(ggplot2) year <- 1990:2010 count <- c(29, 8, 13, 3, 20, 14, 18, 15, 10, 19, 17, 18, 24, 47, 52, 24, 25, 24, 31, 56, 48) df <- data.frame(year, count) my_glm <- glm(count ~ year, family = "poisson", data = df) my_glm$model$fitted <- predict(my_glm, type = "response") ggplot(my_glm$model) + geom_point(aes(year, count)) + geom_line(aes(year, fitted)) now want add these simulated poisson distributions plot: library(plyr) poisson_sim <- llply(my_glm$model$fitted, function(x) rpois(100, x)) the plot should (red points photoshopped): you can convert simulated values vector , use them make new data frame 1 column contains years repeated each 100 times , second column simulated values. poisson_sim <- unlist(llply(my_glm$model$fitted, function(x) rpois(100, x))) df.new<-data.frame(year=rep(year,each=100),sim=poisson_sim) then add simulated points geom_jitter() . g...

so have assignment array. asked use scanner read through text files , record occurrences of each alphabet , store them in table. for example: public class { char[] alphabet = "abcdefghijklmnopqrstuvwxyz".tochararray(); public void displaytable () { (int = 0; < alphabet.length; i++) { system.out.println(alphabet[i] + ": " + count); } } i don't know how construct method store occurrences of each alphabet. it supposed like: public void countoccurrences (scanner file) { //code written here } if text file has line , line : hello world the method ignore integers or symbols , output char appeared in table. d: 1 e: 1 h: 1 l: 3 o: 2 r: 1 w: 1 i can't figure out myself , appreciated! thanks, shy simply use map . read inline comments more info. map<character, integer> treemap = new treemap<character, integer>(); // initialize default value 0 characters (char = 'a'; ...

i using protocol buffers in python , have inside person message repeated uint64 id but when try assign person.id = [1, 32, 43432] i error assigment not allowed repeated field "id" in protocol message object how assign repeated field ? as per documentation , aren't able directly assign repeated field. in case, can call extend add of elements in list field. person.id.extend([1, 32, 43432])

i need run following line , don't know how to. please. here code: wget -q0 --user=user --password=pass \ http://192.168.1.1/userrpm/sysreboot.htm?reboot=reboot > /dev/null os: windows 8.1 thanks. you need wget windows, can download here http://gnuwin32.sourceforge.net/packages/wget.htm open notepad , paste code, save "myscript.bat" make sure doesn't have .txt put "myscript.bat" in same folder wget.exe try it, should work

i totally new @ spotfire environtment. want create new calculated column growth of other column. here data : item || date || value || growth || 12/12/2014 || 102 || || 13/12/2014 || 121 || 19 b || 12/12/2014 || 141 || b || 13/12/2014 || 111 || -30 how create growth column custom expression? i sample code solve similar problem. but, still got error. first of create hierarchy named hirarki include item , date. create custom expression, there's error said "couldnt find hierachy : 'hirarki'" sum([value]) on (intersect(parent([axis.hirarki]),[axis.hirarki])) - sum([value]) on (intersect(parent([axis.hirarki]),previous([axis.hirarki]))) why spotfire couldnt find hierarchy? thank you, cheers i think formula calculates need sum([value]) on ([item],[date]) - sum([value]) on (intersect([item],previous([date])))
