an indirect solution is the following:

lapply(seq(along=denlist), function(i) plot(denlist[[i]], main=paste("var", i)))

I hope it helps.

Subject: [R] passing arguments to FUN in lapply



Suppose I have a nx2 matrix of data, X, the following code generate
density estimation for each column and plot them

denlist <- apply(X, 2, density)
par(mfrow=c(1,2))
lapply(denlist, plot)

Does anyone know how to change the main title of each density plot
to "var 1", "var 2" by passing optional argument "main"? I've tried

lapply(denlist, plot, main=c("var 1", "var 2"))
which generates two same titles "var 1/var 2" and "var 1/var 2"

lapply(denlist, plot, main=list("var 1", "var 2"))
which generates two same titles "var 1"

Both are not I want.
