Dear Uwe,
Thanks very much for your prompt reply.
I include the following pieces of information, alongside a zip file with two
folders where the corpus resides.
###############################
##Full reproducible code:

library("lsa")
# load training text
matrix1 = textmatrix("C:\\Documents and Settings\\tine
stalmans.TINE.000\\LSA\\cuentos\\", stemming=TRUE, language="spanish",
minWordLength=2, minDocFreq=1, stopwords=NULL, vocabulary=NULL)
print(matrix1,bag_lines = 3, bag_cols = 3)
matrix1 = lw_bintf(matrix1) * gw_idf(matrix1) # weighting
space = lsa(matrix1, dims = dimcalc_share()) # create LSA space
#as.textmatrix(space)
# fold-in test and gold standard essays
matrix2 = textmatrix("C:\\Documents and Settings\\tine
stalmans.TINE.000\\LSA\\respuestas\\", stemming=TRUE, language="spanish",
minWordLength=2, minDocFreq=1, stopwords=NULL,vocabulary=rownames(matrix1))
matrix2 = lw_bintf(matrix2) # da NaN si se agrega el idf porque divide entre
0
matrix2fld = fold_in(matrix2, space)
r <- cor(matrix2fld[,"respId1.txt"], matrix2fld[,"respAl1.txt"], method =
"pearson") #use = "complete.obs", method = "pearson");
print(r)

I tried to run a traceback, however when including this command in the code,
it didn't change the original error message.

In addition: There were 16 warnings (use warnings() to see them)
