Mining financial articles - Error in mutate_impl(.data, dots) : 1: failed to load HTTP resource

I believe this is an error from the XML package downloading the finance data; sounds like R is not successfully accessing that data. You might need to do some debugging around accessing the internet through R? Also perhaps try just doing a few of the companies; I have heard some people have trouble with all of those, especially Twitter and IBM.

If it makes you feel better, someone else also got this error when trying to run the code from the book.

Looks like there is some sort of limitation on the corpus's dimension.
The code works if there are only 5 elements in the company vector. Couldnt investigate any further though.

hi,
when I try the code mention in topic modeling part. I got a error mention like this.
Error in LDA(dtm, k, method = "Gibbs", control = list(nstart = nstart, :
Each row of the input matrix needs to contain at least one non-zero entry
Please help me to fix it.
Thank you.

Hello @chankamiperera! I don't think you are using code from our book, because I don't believe we have any Gibbs method fitting at all. If you are running into an error that we might be able to help with, can you make a small, reproducible example to show the error? You also might consider posting your problem on Stack Overflow, because the function LDA() is from the topicmodels package, not our tidytext package, so you might get faster help (or at least help from more people) there. I have SO questions tagged tidytext on a feed so I will always see them.
