Dear R users,

I have data in the following manner

[,1]    [,2]    [,3]    [,4]
6       2       2       2
5       4       4       3

[snip]

I want to arrange all the data in descending order. I have
92 columns in my actual data set. It is therefore
difficult for me to apply order command to each column. Is
there a short way of doing it?

 Do you mean

apply(mydata,2,sort,decreasing=TRUE)

?
