Description Usage Arguments Value Examples

Compute a matrix of distances / similarities between two sets of signatures.

1	sig_dist_matrix(x1, x2, method = "cosine")

`x1`	The first set of signatures (a positive matrix in which each column is a signature). The elements of `x1` will be the rows of the output matrix
`x2`	The second set of signatures, similar data type to `x1`. The elements of `x2` will be the columns of the output matrix
`method`	(as for the `philentropy::distance`) function.

A matrix with dimensions ncol(x1) X ncol(x2) with each element representing the distance or similarity (depending on method) between the corresponding elements of x1 and x2

ex.sigs <- matrix(c(0.2, 0.8, 0.3, 0.7, 0.4, 0.6), nrow = 2)
colnames(ex.sigs) <- c("ex1", "ex2", "ex3")
gt.sigs <- matrix(c(0.21, 0.79, 0.19, 0.81), nrow = 2)
colnames(gt.sigs) <- c("gt1", "gt2")
sig_dist_matrix(ex.sigs, gt.sigs)
