load.ffdf("nonexistent")
Error in setwd(dir): cannot change working directory
I think the error message should be made clearer, especially because users do not expect that loading a ffdf would require changing working directory. This increases the entry cost to use ffbase.
Of course setwd() could be more explicit, but since it isn't and R-core is usually conservative about that, it would be good to check that the directory exists before calling it.
