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

Subject: Re: [R] Problem with lsa package (data.frame) on Windows XP
Please specify reproducible examples, it is almost impossible to help
otherwise. Also, please provide all error messages and a traceback().
Please tell us versions of R and versions of the packages you are using.
If you are sure this is an error in the package, please send that
reproducible example to the package maintainer.

Dear R team,
The following piece of code (to use the lsa package) works fine on my
mac os x, but when I run the same code on Windows XP, it doesn't work
any more.
### code:
library(lsa)
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)
space = lsa(matrix1, dims = dimcalc_share())
as.textmatrix(space)
### the following line fails on windows XP
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)
matrix2fld = fold_in(matrix2, space)
r - cor(matrix2fld[,respId1.txt], matrix2fld[,respAl1.txt],
method = pearson)
print(r)
An error occurs when creating the second textmatrix with the
vocabulary of the first. The error I get is:
in data.frame(docs = basename(file), terms = names(tab), Freq = tab, :
arguments imply differing number of rows: 1, 0
When I change the vocabulary argument to NULL, it doesn't report this
error any more; however, then the code will fail on the fold_in
method further down.
I found another user who reported this same problem on-line; however,
I didn't find any answers.
Thank you very much in advance for your reply.
Tine.
