merge resulting in "Error in isReallyReal(by): x must be of type double."

Hi All,

Odd error with data.table version 1.11.6 downloaded from CRAN a couple of days ago.

library(data.table)

a <- data.table(a = c("a","b"), b = c(1,2))
b <- data.table(a = c("a","b"), b = c(1,3))

merge(a,b, by = "a")

resulting in

#> Error in isReallyReal(by): x must be of type double.

I am guessing it is a problem using a character column as a key? I also tried running the current 1.11.7, with the same result. Any ideas?

can you try closing all R sessions and reinstalling first?
