x[-which(x < 0, arr.ind=TRUE)[,1],]
but I'm sure someone will suggest an easier way.

Hello All,
I would like to remove the entire row, if there is any negative element in
that row. What is the best way to do that?
For example,
x<-matrix(c(2,-1,-2,3,5,6,-3,7,4,2,1,0), 4, 3)
the returning matrix should look like
[,1] [,2] [,3]
[1,] 2 5 4
[2,] 3 7 0
Thank you in advance,
FM
