Hi all, I have a text classification task which is classification of a Control group and Alzheimer group texts. I have generated DocumentTermMatrix for both groups and then created a list with one extra element showing the group name if it's Alzheimer or control group, for example for the Alzheimer group:
frequenciesAlzheimer=DocumentTermMatrix(corpus) freqlistAlz=list(type="alzheimer",frequenciesAlzheimer) List of 2 $ type: chr "alzheimer" $ :List of 6 * ..$ i : int [1:8678] 1 1 1 1 1 1 1 1 1 1 ... ..$ j : int [1:8678] 1 2 3 4 5 6 7 8 9 10 ... ..$ v : num [1:8678] 1 1 1 1 1 2 1 1 2 1 ... ..$ nrow : int 255 ..$ ncol : int 1091 ..$ dimnames:List of 2 .. ..$ Docs : chr [1:255] "1" "2" "3" "4" ... .. ..$ Terms: chr [1:1091] "alright" "bad" "boy" "cookie" ... ..- attr(*, "class")= chr [1:2] "DocumentTermMatrix" "simple_triplet_matrix" ..- attr(*, "weighting")= chr [1:2] "term frequency" "tf" and I have the same list for control group,now my question is why I don't get the name of my DTM as the second element of my list? in the line marked by * I need to have $frequenciesAlzheimer : List of 6 but there's no name, does anyone know how should I solve this? Thanks for any help!
