RowSums and colSums for a sparse matrix
sparse_Sums(sparse_matrix, rowSums = FALSE)
a vector with either the row- or the column-sums of the matrix
a sparse matrix
either TRUE or FALSE. If TRUE then the row-sums will be calculated, otherwise the column-sums
library(textTinyR) tmp = matrix(sample(0:1, 100, replace = TRUE), 10, 10) sp_mat = dense_2sparse(tmp) spsm = sparse_Sums(sp_mat, rowSums = FALSE)
