[R] xyplot with all columns of a data.frame on a single plot

[Felix Andrews]

One method:

dd <- do.call(make.groups, mydata[,-1])
dd$X <- mydata$X
xyplot(data ~ X | which, dd)

Another method:

form <- paste(paste(colnames(mydata)[-1], collapse = " + "), "~ X")
xyplot(as.formula(form), mydata)

Yet another method:

library(latticeExtra)
xyplot.list(mydata[,-1], FUN = function(z, ...) xyplot(z ~ mydata$X, ...))
