[Rd] Median

[Jose Sierra]

Hello.

I need calculate the median of several column of a data.frame, in a new 
column of this data frame, but the median operator only calculate from a 
vector.

I have made a functionc that calculate the median but it is very slow. 
Are there any method in any package to calculate this?

Best regards.
Jose Sierra.
