x = matrix(rnorm(100), ncol = 10) apply(x, 1, median) Hope this helps, Greg Edward Chen wrote:
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!
