Re: [R] sampling rows with values never sampled before

Mike, There may be a more efficient way to do this, but this works on your example. # mix up the order of the rows mix - dat[order(runif(dim(dat)[1])), ] # get rid of duplicate x1s and x2s sub - mix[!duplicated(mix[, x1]) !duplicated(mix[, x2]), ] sub Jean On Mon, Jun 22, 2015 at 11:42 AM, C

Re: [R] Omitting NA's using dcast (reshape2 package)

You could apply na.omit() to just the columns you are using: dcast(na.omit(df[,1:2]), v1 ~ v2, length, margins = TRUE) Using v2 as value column: use value.var to override. v1 X Y Z (all) 1 A 1 2 2 5 2 B 1 2 1 4 3 (all) 2 4 3 9 -
