I have a data.frame with ~100 columns and I need a barplot for each column produced and saved in some directory.
I am not sure it is possible - so please help me. this is my loop that does not work... vars <- list (substitute (G01_01), substitute (G01_02), substitute (G01_03), substitute (G01_04)) results <- data.frame ('Variable Name'=rep (NA, length (vars)), check.names=FALSE) for (i in 1:length (vars)) { barplot(table(i),xlab=i,ylab="NuomonÄ—s") dev.copy(png, filename="/my/dir/barplot.i.png", height=600, width=600) dev.off() } questions: Is it possible to use the i somewhere _within_ a file name? (like it is possible in other programming or scripting languages?) Since I hate to type in all the variables (they go from G01_01 to G01_10 and then from G02_01 to G02_10 and so on), is it possible to shorten this list by putting there another loop, applying some programming thing or so? -- Donatas Glodenis http://dg.lapas.info ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
