I installed the tm package in R to do some text mining analysis. After creating a corpus I wanted to use the tm_map() function, which throws the following error message:

The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec().Break on

Anybody an idea why this message turns up?

Here's more code for clarification:

> require(tm)
Lade nötiges Paket: tm
> a <-Corpus(VectorSource(chi2014_df$text))
> a
A corpus with 70 text documents
> a <-tm_map(a,tolower)
The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec().
Break on

I'm using R 3.0.1 GUI 1.61 Snow Leopard build (6492) on OSX 10.7.5

Does the same thing happen with the package's examples with the built in data sets? – Tyler Rinker Sep 08 '13 at 21:48
Ok the later problem is solved by the snowball package ! – meier_flo Sep 09 '13 at 19:04
