colSds: Standard deviation of columns and rows of large matrices
In proxyC: Computes Proximity in Large Sparse Matrices
colSds R Documentation
Standard deviation of columns and rows of large matrices
Description
Produces the same result as apply(x, 1, sd) or apply(x, 2, sd)
without coercing matrix to dense matrix. Values are not identical to
sd because of the floating point precision issue in C++.
Usage
colSds(x)
rowSds(x)
Arguments
x
matrix or Matrix object
Examples
mt <- Matrix::rsparsematrix(100, 100, 0.01)
colSds(mt)
apply(mt, 2, sd) # the same
