In order to perform further calculations on this matrix I need to convert it to a regular matrix. I want to use the as.matrix() command. However, it returns the following error: cannot allocate vector of size 364.8 MB.> corpA corpus with 1859 text documents> mat<-DocumentTermMatrix(corp)> dim(mat) 1859 25722> is(mat) "DocumentTermMatrix"> mat2<-as.matrix(mat)Fehler: kann Vektor der Größe 364.8 MB nicht allozieren # cannot allocate vector of size 364.8 MB> object.size(mat)5502000 bytesFor some reason the size of the object seems to increase dramatically whenever it is transformed to a regular matrix. How can I avoid this?Or is there an alternative way to perform regular matrix operations on a DocumentTermMatrix? less
