Hi
I have the feeling, that the argument stringsAsFactors has no impact in the
function expand.grid:
a <- c("PR", "NC", "A2", "BS")
b <- c(1, 0.5, 0.25, 0.125, 0.0625, 0.03125)
class(expand.grid(css, fscs, stringsAsFactors=FALSE)[[1]])
[1] "factor"
class(expand.grid(css, fscs, stringsAsFactors=TRUE)[[1]])
[1] "factor"
Also, when I look at the code of expand.grid, stringsAsFactors does not
occur in the code.
Am I missing something?
