colMeans in a data.frame with numeric and character data

summaryBy in the doBy package can do that.  The builtin iris data
set has 4 numeric columns and one factor column:
library(doBy)
summaryBy(.~1, iris, fun = mean, keep = TRUE)
Sepal.Length Sepal.Width Petal.Length Petal.Width
1     5.843333    3.057333        3.758    1.199333

Hi all,

I would like to know if it is posible by, someway, to get colMeans from
a data.frame with numeric as well as character data, dispersed all over
the object. Note that I would like to get colMeans neglecting character
data.

I am really in need of some function proceeding in that way?

All the best
