sparsity | R Documentation |
Determine the sparsity of a matrix, distributed, dense, or otherwise.
## S4 method for signature 'matrix'
sparsity(x, count = "zero", out = "count", tol = .Machine$double.eps)
## S4 method for signature 'vector'
sparsity(x, count = "zero", out = "count", tol = .Machine$double.eps)
## S4 method for signature 'dmat'
sparsity(x, count = "zero", out = "count", tol = .Machine$double.eps)
x |
numeric matrix |
count |
character; options are "zero" and "other". The former counts the number of zeros, while the latter counts the number of non-zeros ('other' elements). |
out |
character; options are "count", "proportion", and "percent". This
determines whether a pure count, proportion of |
tol |
numeric; the tolerance for numerical zero. This is ignored if the input data is integer/logical. |
The sparsity count of a matrix is returned.
