Hi everyone, I'm having trouble figuring out how to split a dataframe more than once. Let's say I have a dataframe d with a certain column called splitcol composed of four possible ordinal values. The same dataframe has two other columns, col1 and col2, that have one of two possible values each. I'd like to split d$splitcol based on col1 and col2 so I can report frequencies of the subgroups. So if col1 and col2 can each have two different value...

...f(!is.na(plotFileName)) { print(paste("Saving Zonal plot to file ",plotFileName,".png",sep="")) print("(To display instead, do not pass any 'plotFileName' argument to cro.zone.plot function.)") maxLayout <- c(0,length(unique(miniDataSet$splitCol))) png(filename = paste(as.character(plotFileName),".png",sep=""),width=(1.2*plotSize*(maxLayout[2]^(1/3))), height=(plotSize*(maxLayout[2]^(1/3)))) } else { devAskNewPage(ask = TRUE) maxLayout <- c(0,min(16,length(unique(miniDataSet$splitCol)))) } l...

...vely long) function script that generates a levelplot. I don't want to include all of the code, so I have attached in file "miniDataSet.csv" an example for the data set "miniDataSet" that is called below. The function works OK, except that when the variables in the "splitCol" column get very large (as they are in this data set I have attached), it cannot print the whole thing in the "trellis subplot", the little title above each sub-plot that is generated. I have also attached a picture which shows how the graph looks (when run in my environment... hope...
