[R] Rattle not reading files on windows 7

[IGNACIO PEREZ VELEZ]

Hi,

I migrated to Windows 7 and now rattle does not read files whenever I try to read a file I get the following error:

"Error en sqrt(ncol(crs$dataset)) : 
  Argumento no numérico para función matemática"

In english:

"Error on sqrt(ncol(crs$dataset)) : 
  Non numeric argument for a mathematical function"

Any clue on what is going on?

Thanks,

Ignacio
