if your matrix has many rows you might want to consider rowMedians from
Bioconductor package Biobase.

Edward,
See ?apply
x = matrix(rnorm(100), ncol = 10)
apply(x, 1, median)
Hope this helps,

Hi,
I tried looking through google search on whether there's a way to
computer
the median for each row of a nxn matrix and return the medians for
each row
for further computation.
And also if the number of columns in the matrix are even, how could I
specify which median to use?
Thank you very much!
