Hello all:

I have a character variable (foo) that contains the names of some numeric
variables. For my application, I'd like to cbind the numeric variables and
calculate the row mean using the character variable. I think I do this using
do.call but the function to call using do.call is eluding me! Example below
and help appreciated.

foo <- c("x1","x2","x3","x4")

# what I want...

bar <- function(aCharVaraible) {
    cbind(stuff goes here)
    rowMeans(stuff goes here)
# how I want to get it...
