| rowSums.dist {cba} | R Documentation |
Compute the row (column) sums for a sparse symmetric (distance) matrix.
rowSums.dist(x, na.rm = FALSE)
x |
an object of class dist. |
na.rm |
logical, should missing values (including NaN) be
omitted from the summation? |
This function is more efficient than expanding an object of
class dist to matrix and using rowSums.
A numeric vector of row sums.
