Hi,
In continuation to my initial mail I also observed that as I include more
number of tweets, the likelihood of getting this error increases.
Platform I’m using:
- Mac Yosemite
- R version 3.2.2(RStudio)
I have below questions:
- Does this error has to do anything with the default locale set in R session?
I have had it set from Mac terminal “defaults write org.R-project.R force.LANG
en_US.UTF-8”
- Before creating the Corpus() I had the tweets converted to character by using
this command tw_text <- sapply(tw, function(x) x$getText()). Is it the
recommended approach ?
How should I go about getting this issue resolved ?
Regards,
Sunny Singha
