[R] as.ffdf.data.frame now breaks if using pattern

Dear All,

I am using package ff. In version 2.1-1 it was possible to use
"pattern" with as.ffdf.data.frame:

d <- data.frame(x=1:26, y=letters, z=Sys.time()+1:26)
as.ffdf(d, pattern = paste(getwd(), "/fftmp", sep = ""))

With the latest version, the last command crashes. I wonder if the new
behavior is intentional or a bug. If intentional, what is the
recommended way of using "pattern" now?
