i new r programming , have few questions regarding matrices in r. i have function returns matrix. want check if returned matrix empty or not. how check in r? if integer can check is.null(someinteger) . how check same in case of matrices? also, integer can initialized x <- null . if have want initialize matrix. initialize mat <- matrix() or there other way? mat can of size. thankyou. there question of meant "empty" here test if matrix m has 0 length: length(m) == 0 regarding initializing matrix initializes 0x0 matrix: m <- matrix(, 0, 0) and initalizes 1x1 matrix containing na: m <- matrix() and initializes nr nc matrix of na values: m <- matrix(, nr, nc) not clear whether of these useful. may want describe trying accomplish. why need initialize @ all?

i new r, , trying create simple barplot. have been able create barplot correct values, single color bars. if change code ( using table() instead of as.table() ), wrong values, correct colors on graph. how can as.table() accept multiple colors in graph? here altered version of code: a=30 b=20 c=10 d=15 x=matrix(c(a,b,c,d),ncol=4,byrow=true) colnames(x)=c("label1","label2","label3","label4") rownames(x)=c("percentage") x=as.table(x) color=c("red","blue","green","orange") barplot(x,main="x",ylab="percent",cex.names=0.75,col=color) passing in vector instead of table should trick: barplot(x[1, ], main="x", ylab="percent", cex.names=0.75, col=color) or barplot(x["percentage", ], main="x",ylab="percent",cex.names=0.75, col=color)

i know how code in order fill down column, have few conditions can't find out how implement. i want fill down until last row (that contains value @ all) or next cell within column contains information. the data looks this a 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 b 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 c 1 2 3 4 5 6 7 8 9 10 d 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 e 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 so can see, code needs recognize how stop @ b (and not copy on it) when copying down column. code needs stop @ last row values in when dra...

i trying split csv string comma delimiter. val string ="a,b,"hi,there",c,d" i cannot use string.split(",") because split "hi,there" 2 different columns. can use regex solve this? came around scala-csv parser dont want use. hope there better method solve problem.i know not trivial problem. it'll helpful if people can share approaches solve problem. use univocity-parsers csvparser instead of parsing hand. csv harder think , there many corner cases cover. found one. in short, need library read csv reliably. univocity-parsers used other scala projects (e.g. spark-csv) i'll put example using plain java here, because don't know scala, you'll idea: public static void main(string ... args){ csvparsersettings settings = new csvparsersettings(); //many options here, check documentation csvparser parser = new csvparser(settings); string[] row = parser.parseline("a,b,\"hi,there\",c,d");...

i want appcompat-styled dialog - background, title, button position, button tint etc. - containing fragment. with custom dialogfragment oncreatedialog() can return appcompatdialog , in oncreateview() new layout can inflated , childfragmentmanager can used replace placeholder view fragment. resulting dialog otherwise empty box no buttons. can manually added dialog's layout no styling appcompat. the same applies if make target fragment extend dialogfragment . to appcompat buttons can use alertdialog.builder , , use .setview() set layout, can't find way set fragment content. if try childfragmentmanager.begintransaction().replace() oncreatedialog() get: java.lang.illegalstateexception: fragment not have view this seems because, after using builder.setview() or dialog.create() dialog.setview() , oncreateview() , getview() return null. the second answer here seems cover quite comprehensively doesn't suggest favourable solution: https://stackoverflow....

i'm using react js flux architecture , having trouble resolving issue asyncronous request affects more 1 store. have form store , results store. submitting form component sends off action results store (rather dispatcher registers in results store) fires ajax request external api fetches data based on serialized form info (from results store). response populates results store, initializes results component state. works expected. issue comes when there errors in form. if there errors (but still 200 response code) make through api sends me error response object. issue is, i'm in results store, , need these errors form store. following flux kata, action required update form store, doesnt seem right fire action store. flux cycle have going formcomponent --> resultsaction.fetchresults(relaventformdata) --> resultstoredal.fetchresults --> $.ajax.success: if (response.errors){ //update formstore response.errors } formcomponent gets states formstore (which h...
