I can appropriately create the grouped lines (but without the single data markers) with following code: by(expt1,expt1[,3:4],function(q) xyplot(q[,9] ~ q[,8], groups=q[,2], data=q, col="black", ty...

...of my variables to appear on the x-axis rather than ascending numbers? I have used: termplot(fm, se=T, axes=FALSE, col.se="black") axis(1, 1:4, LETTERS[1:4]) axis(2) box() to replace the numbers with letters - but I want to be able to have the names of the plotted varibles from say Data$Expt1, so that instead of A, B, C - I have Control, Subs1, Subs2 etc Can anyone tell me how I can do this?
