Hi, I had this error:

predMatrix <- create_matrix(predictionData, originalMatrix=dtMatrix)
Error in if (attr(weighting, "Acronym") == "tf-idf") weight <- 1e-09 : argument is of length zero

any suggestion?
Thanks,
F.

That worked for me:

Run this:
trace("create_matrix",edit=T)
In the source code box that pops up, line 42 will have a misspelling of the word "acronym". Change the "A" to an "a" and hit "Save" - it should work fine after that.

Hi Alexandre,

Your tutorials are awesome! But I have one question to which I couldn't find a solution.

Short description: I have 2 files. One is for training, the second one is for testing. Both are labeled and contain 2 columns: "sentence", "label". I have build a model according to your tutorial here http://www.svm-tutorial.com/2014/11/svm-classify-text-r/ and I have tried to get some results.

Question: How can I now calculate precision/recall/accuracy/F1-measure in this case? Really need your help :(
