Dear all, I'm a new R user and I find myself in trouble with some of the plot functions. I'm trying to save a sequence of plots to eps files using a for loop, but I get only empty figures. In each iteration of the for loop I fit a nlme model and I'd like to plot its prediction of the dependent variable values. This is the code I'm using to plot the figures (I removed the commands I use to fit the model, but they are OK)
postscript(file="saReg%03d.eps",onefile=FALSE) for (i in 1:length(names(DatasetSa))) { #[...] plot(augPred(DatasetGrp.fit,primary = ~R, level = 0:1),title=names(DatasetSa)[i]) #[...] } dev.off() When I run this code I only get one empty figure even though the loop is executed 70 times. If I try to run the command plot(augPred(DatasetGrp.fit,primary = ~R, level = 0:1),title=names(DatasetSa)[i]) outside the loop everything goes fine. I also tried to open and close a device in each loop iteration, for (i in 1:length(names(DatasetSa))) { #[...] fignam <- paste("SaReg",i,sep="."); fignam <- paste(fignam,".eps",sep=""); postscript(file=fignam) tempData<-augPred(DatasetGrp.fit,primary = ~R, level = 0:1) plot(tempData) dev.off() #[...] } in that case I get the correct number of eps files but they are all empty. I would really appreciate you help.
