R help - Jul 2001 - boxplot(list(m[,1],...,m[,c]))

Given a matrix m, I would like to obtain a boxplot of the columns of m; in 
other words, boxplot(list(m[,1],...,m[,ncol(m)])). At the moment, I am using

colpart <- function(m){
         L <- list(rep(0,ncol(m)))
         for(i in 1:ncol(m)){
                 L[[i]] <- m[,i] }
         return(L)}
boxplot(colpart(m))

for this purpose. Surely there must be a more eloquent way!

Indeed!
It's even in the `Examples' section of  help(boxplot) :

Use
	boxplot(data.frame(m))

Take a look at R_HOME/doc/html/function.html ....  The browser-based search
engine was not on that page, but help.start() will lead you to where it has
always been.
