This came from an error in reg-tests-1.R
> x <- as.data.frame(x=I("C"))[[1]]
> class(x)
[1] "AsIs"
> library(methods)
> detach("package:methods")
> search()
[1] ".GlobalEnv" "package:ctest" "Autoloads" "package:base"
> x <- as.data.frame(x=I("C"))[[1]]
> class(x)
[1] "AsIs" "character"
My reading is that this should not happen.
