[R] Error in using tokens script

[PIKAL Petr]

Hi.

Most probably SMSSpamCollection$Message is not character, corpus or tokens object (which error message politely suggests).

You need to change it to be correct mode

functions ?str, ?mode, ?typeof

to see your objects.

And maybe also R intro chapter about objects and its differences.

Cheers
Petr
