I am using 'tm' package for text mining. I use the function
findFreqTerms to
obtain the frequent words based on their frequency in the term document
matrix.
The following is the example given in the help page of this function:
library("tm")
data("crude")
tdm <- TermDocumentMatrix(crude)
findFreqTerms(tdm, 2, 3)
The first three columns of the document term matrix are shown below:
(bpd) (bpd). (gcc)
0 0 0
0 0 0
0 0 0
0 0 0
0 0 0
1 0 0
0 0 0
0 0 0
0 0 0
1 0 0
1 0 0
0 0 1
0 0 0
0 1 0
0 0 0
0 0 0
0 0 0
0 0 0
0 0 0
0 0 0
The first term "(bpd)" has a frequency of 3 whereas the second and
third
terms have a frequency of 1 which is below the lowfreq = 2 specified.
Can someone help me whether this is the right way of interpreting this
function??? If so, is there a bug in the package??
Thank you.
Ravi
