Dear all This may be obvious, but I cannot get it working. I'm trying to subset & sort a data frame in one go. x <- iris x$Species1 <- as.character(x$Species) ##subsetting alone works fine with(x, x[Sepal.Length==6.7,]) ##sorting alone works fine with(x, x[order(Sepal.Length, rev(sort(Species1))),]) ##gets subsetted, but not sorted as expected with(x, x[(Sepal.Length==6.7) & order(Sepal.Length, rev(sort(Species1))),]) ##gets subsetted, but sorts very strangely xa <- with(x, x[Sepal.Length==6.7,]); with(xa, xa[order(Sepal.Length, rev(sort(Species1))),]) xa <- with(x, x[Sepal.Length==6.7,]); with(xa, xa[order(rev(sort(Species1))),])
I've checked The R Inferno, Quick-R and several other places with no obvious solution. Any ideas?
