Selecting columns with colnames doesn't run? #3

Closed KensukeOkamuraTK closed 8 years ago

KensukeOkamuraTK commented 9 years ago

Hello. I use gmatrix@GitHub on TSUBAME (super computer at Tokyo Institute of Technology in Japan).

I feel good at gmatrix, that is good way when handling variables on GPU. But I cannot select columns from gmatrix with colnames. If it is bug, then I hope fix it.

library(gmatrix)
(m <- gmatrix(1:12, 3, 4))

colnames(m) <- c("a", "b", "c", "d")

m[, 3] # not run
m[, 3:4] # not run
m[, 1:4] # run
m[, T] # notrun
m[, c(T, F, T, F)] # not run
m[, c(T, T, T, T)] # run
m[, "a"] # not run
m[, c("a", "b", "c", "d")] # illeagal result

Should work now, if you use the development version. Thanks, nathan
