Thanks mate, will get the zoo package ASAP. I have been working on the file open/save part, and it works as planned except for one bit. When I save it, it does not save as the relevant file type.
This is again my code: require(tcltk) fileName<-tclvalue(tkgetSaveFile(filetypes="{{PNG Files} {.png}} ")) png(fileName) barplot(Ann,main="Annual Rainfail Data", xlab="Year",ylab="Rainfall (mm)",ylim=c(0,ymax),col="blue",space=0,names.arg=c(kent[,2]), cex.names=0.8) legend("topleft",c("This picture"),bty="n") dev.off() When I go to save it, the corrent save window pops up, and it has the png file format selected, yet when I type in a name and save, it is saved without a file type. What am I doing wrong?
