Well, when I try to run your sample code, I get one figure and a bunch of error messages.
How about an actual executable example and the requested basic information on your OS, version of R, etc? That would make it a lot easier to offer useful suggestions (by which I mean possible). > d=data.frame(age=rnorm(100,40,8),ht=rnorm(100,170,15)) > > tiff(file=paste("test","%03d",".tif",sep="")) > > hist.data.frame(d) Error: could not find function "hist.data.frame" > > datadensity(d) Error: could not find function "datadensity" > > par(mfrow=c(1,2),mar=c(3,3,3,3)) > > boxplot(d$age) > > hist(age) Error in hist(age) : object 'age' not found > > dev.off() null device 1 I get a boxplot only. Can you actually run this code without error messages? Even if you have loaded whatever library the missing plot functions came from, hist(age) is not going to create a plot, thus you would only ever get three files.
