search for: ycorr

Hello R gurus, I have a simple routine using for loops that i was just trying to make it faster y <- rnorm(10) Nindiv <- 10 x <-matrix(sample(c(0:2),50,re = T),10) gtemp <- rnorm(10) ycorr <- array(0,c(Nindiv,1)) for (i in 1:Nindiv) { for (k in 1:ncol(x)) { ycorr[i] <- y[i] - x[i,k]*gtemp[k] } } It works fine but I wanted to make it faster and I think an apply function could probably solve this problem. Any suggestions? Thanks -- View this message in context: http://r.789...
