Hello, See the following example.
x <- matrix(rnorm(2000), ncol = 2) idx <- sample(nrow(x), 0.7*nrow(x)) x2 <- x[idx, ] nrow(x2) # 700 x3 <- x[-idx, ] nrow(x3) # 300 Hope this helps, Rui Barradas Em 19-11-2012 17:16, Eddie Smith escreveu:
Hi guys, I have 1000 rows of a dataset. In my analysis, I need 70% of the data, run my analysis and then use the remaining 30% to test my model. Could anybody kindly help me on this?
