Also having problem with session 10.4

[mauro.gent...@gmail.com]

Building on the previous message, I am also having problems in session 10.4:

When I call the very first code line 

myTdm <- TermDocumentMatrix(myCorpus, control=list(wordLengths=c(1,Inf)))

I get the following error:

Error in UseMethod("meta", x) : 

  no applicable method for 'meta' applied to an object of class "character"

In addition: Warning message:

In mclapply(unname(content(x)), termFreq, control) :

  all scheduled cores encountered errors in user code

Hi Mauro,

 

See discussions at https://www.linkedin.com/groups/Got-Warnings-when-I-use-4066593%2ES%2E5900922839627747329, where there are new replies.

 

I think it is caused by the changes in tm v0.6 from tm v0.5-10. I haven't played much with tm v0.6, and will investigate it later. Current too busy to improve the code for tm v0.6.

A quick and simple way is to use tm v0.5-10, based on which all original code can run successfully without any changes.

 

Please post your futurtion questions to the RDataMining group on Linkedin at http://group.rdatamining.com/, instead of here. Thanks.

Regards

Yanchang
