cosine {coop} | R Documentation |
Compute the cosine similarity matrix efficiently. The function
syntax and behavior is largely modeled after that of the
cosine()
function from the lsa
package, although
with a very different implementation.
cosine(x, y, use = "everything", inverse = FALSE)
tcosine(x, y, use = "everything", inverse = FALSE)
x |
A numeric dataframe/matrix or vector. |
y |
A vector (when |
use |
The NA handler, as in R's |
inverse |
Logical; should the inverse covariance matrix be returned? |
See ?coop-package
for implementation details.
The n\times n
matrix of all pair-wise vector cosine
similarities of the columns.
