Hello! How to change a color (or linewidth) of border in lattice 'barchart'? I am trying barchart( (......) - my arguments panel=function(x,y,color,subscripts,groups,...) { panel.barchart(x=x,y=y,box.ratio=2,col=color,border=FALSE) })) or ... panel.barchart(x=x,y=y,box.ratio=2,col=color,border='transparent') ... or

Hello! I have data frame with 'weights' in one of the columns. I need to compute weighted mean on another column other factor variable and i am trying to: res<-tapply(data$k,list(data$model),weighted.mean,w=data$w,na.rm=T) and i get: Warning messages: 1: longer object length is not a multiple of shorter object length in: x * w 2: longer object length is not a multiple of shorter

Hello! I have a dataset with NA's in some variables (factors), for example: $ P67 : Factor w/ 2 levels "-","+": NA 2 1 NA NA 2 1 1 2 NA ... I need to use 'xtabs' like xtabs(~x$P67) It works well and produces something like this: x$P67 - + 779 1318 but i want to compute NA's too, like this: x$P67 - + NA 779 1318 137 I am trying

Hi! I have a source file - for example 'my.R' - which uses some functions from 'lattice' library. It looks like that: library(lattice) pr<-xtabs(W~ff$'q1'+ff$'q2',data=ff) pr<-pr/rowSums(pr)*100 pr<-as.data.frame(pr) barchart(pr[[2]]~pr[[3]]|pr[[1]], horizontal=TRUE, as.table=TRUE, xlab=NULL, ylab=NULL, col="plum",

Hello! When I am trying to produce plot with text with pointsize 30 or greater R sets up a default pointsize of 12 on plot. I need to set up a large pointsize to make large jpeg or png files (with good resolution). I can write text on plot with pointsizes 18,20,22, but i cant write text with pointsizes 25,26 and greater and i can not understand - why? Is there are any restrictions in R? Or what?

Maybe its slightly off-topic, but can anybody help with computing entropy on matrix of probabilities? Guess we have a matrix of probabilites, A, 2x2, something like this: z x 0 1 2 3 4 0 0.063 0.018 0.019 0.016 0.000 1 0.011 0.162 0.040 0.042 0.003 2 0.015 0.030 0.164 0.033 0.002 3 0.012 0.035 0.036 0.159 0.002 4 0.004 0.021 0.018 0.013 0.082 sum(A)=1 Can i

Hello! I have dataset where one variable is 'multiresponse', like this: [1] "1 2" "1 2 3" "4" "1 4" "4 3" etc. 'responses' separated by space. observations in different 'rows' of data.frame. I can do strsplit(data$var,' ') and make a list, where multiple responses are elements of character vectors, like this: $

Hello! I am trying to compute minimal time on some data like this: mt<-tapply(mrsh$time1,list(mrsh$var1,mrsh$var2),min): a b 145 1054800600 1054789800 340 1054804500 1054794600 349 1054820400 1054792800 55 1054800600 1054789200 57 1054814100 1054791000 78 1054822200 1054790400 843
