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.
