Hello list
I am trying to solve a problem when drawing a figure related to the
dataframe below.
I draw V6 in Y axes and V3 as X axes. The data are grouped by V1 AND V2.
I use this commande to make it:
xyplot(cm[,6]~cm[,3],type="b",group=interaction(cm[,1],cm[,2],sep="/"),
auto.key =list( title="Makespan en fonction de beta", points = FALSE,
columns=2, lines = TRUE)
,data=cm,xlab=expression(beta),ylab="Ratio")
The problem is that, R puts (for example) the entry C/D in the legend,
however, I have no such entry. Note that R it does not draw a line for that
entry.
So, the question : how to do to remove the empty groups from the legend.
Cordially
