Dear all, I am trying to use xyplot inside a function plotme<-function(dataframe) { xyplot(x~y|z,data=dataframe) } x,y,z are members of the data frame. When calling function library(lattice) plotme(dataframe) nothing happens. (R-1.8.0, SuSe Linux 8.1) What am I doing wrong? Many thanks in advance Peter
