similarities: Apply a function to a list of similarities
In BioCor: Functional similarities

Description Usage Arguments Value Note Author(s) See Also Examples

Function to join list of similarities by a function provided by the user.

1	similarities(sim, func, ...)

`sim`	list of similarities to be joined. All similarities must have the same dimensions. The genes are assumed to be in the same order for all the matrices.
`func`	function to perform on those similarities: `prod`, `sum`... It should accept as many arguments as similarities matrices are provided, and should use numbers.
`...`	Other arguments passed to the function `func`. Usually na.rm or similar.

A matrix of the size of the similarities

It doesn't check that the columns and rows of the matrices are in the same order or are the same.
