In proxyC: Computes Proximity in Large Sparse Matrices
colZeros R Documentation
Number of zeros in columns and rows of large matrices
Description
Produces the same result as applying sum(x == 0) to each row or column.
Usage
colZeros(x)
rowZeros(x)
Arguments
x
a base::matrix or Matrix::Matrix object.
Examples
mt <- Matrix::rsparsematrix(100, 100, 0.01)
colZeros(mt)
apply(mt, 2, function(x) sum(x == 0)) # the same
