Dear all, I got one problem here and hoping someone can help me on this. Say I have a 50 by 2 matrix and I don't know how to randomly select:
1. a pair of observations from the last 10th of the 50 observation from the matrix. 2. how to select randomly an observation from the first 5 observations of the second column in the matrix? Thanks....hope to hear from someone soon -- View this message in context: http://www.nabble.com/How-to-select-randomly-from-a-matrix--tp22410551p22410551.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
