Hi, How could i generate random real numbers between 0 en 2*pi? Thanks, Frederik [[alternative HTML version deleted]]

Hello, i have a 50*100 matrix, with real numbers. How do i sort each column? Now i sort it with a for-loop but this take a lot of time... Thank you, Frederik [[alternative HTML version deleted]]

Hi, I want put some values in the last column of a matrix b. But every time again there comes the same error on the screen... > b <- array(0, c(5,5)) > m<-matrix(runif(20,0,2*pi),5) # the sinus of this kind of values i want put in the last column of b, m is a 5*4 matrix > n<-5 > for(i in 1:n){ + a2<-1 + for(k in 1: n-1){ + a2<-a2*sin(m[i,k]) + } +
