[R] error in calling source(): invalid multibyte character in parser

[Luca Meyer]

How would I go by doing that? I have tried with:

source("file.R", encoding="it_IT.UTF-8")

But I get

Error in file(file, "r", encoding = encoding) : 
  unsupported conversion from 'it_IT.UTF-8' to ''

Thanks,
Luca

PS:  "it_IT.UTF-8" is what I get under locale when I run sessionInfo()

If that is the cause, the fix is to standardize things to use the same locale. You can convert the encoding of your source file using the iconv utility (in a Terminal window).
