#' @name conversions
#' @title Conversions between matrix types
#' @description Convenience functions for converting to different sparse matrix formats,
#' between pairs of classes which might not be supported in the `Matrix` package.
#'
#' These come in the form of explicit functions 'as.<type>.matrix' (see below),
#' as well as registered conversion methods to use along with `as(object, type)`, adding
#' extra conversion routes which are missing in the `Matrix` package for output
#' types `dgRMatrix`, `lgRMatrix`, and `ngRMatrix`.
#' @details The functions internally might use some routes of `as(x, "?sparseMatrix")`, so they might work
#' with other object classes if they register a conversion method for `Matrix` base
#' types.
#'
#' When passed a vector, the functions `as.csr.matrix` and `as.coo.matrix` will
#' assume that it is a row vector, while `as.csc.matrix` will assume it's a column vector.
#' @param x A matrix which is to be converted to a different format.
#'
#' Supported input types are:\itemize{
#' \item Sparse matrices from `Matrix` package, in any format.
#' \item Sparse vectors from `Matrix` in any format.
#' \item Dense matrices from base R (class `matrix`).
#' \item Dense vectors from base R (classes `numeric`, `integer`, `logical`).
#' \item Dense matrix or vector from package `float` (class `float32`).
#' \item `data.frame`, `data.table`, and `tibble`.
#' }
#' @param binary Whether the result should be a binary-only matrix/vector (inheriting from
#' class `nsparseMatrix`/`nsparseVector` - these don't have slot `x`).
#' Can only pass one of `binary` or `logical`.
#' @param logical Whether the result should be a matrix/vector with logical (boolean) type
#' (inheriting from `lsparseMatrix`/`lsparseVector`).
#' Can only pass one of `binary` or `logical`.
#' @param integer Whether the result should be a vector with integer type ('isparseVector').
#' @param sort Whether to sort the indices in case they are not sorted. Note that it will
#' perform deep copies of the indices and values along the way.
#' @return A sparse matrix/vector, with format:\itemize{
#' \item CSR (a.k.a. `RsparseMatrix`) when calling `as.csr.matrix`
#' (class `dgRMatrix`, `ngRMatrix`, or `lgRMatrix`, depending on parameters `binary` and `logical`).
#' \item CSC (a.k.a. `CsparseMatrix`) when calling `as.csc.matrix`
#' (class `dgCMatrix`, `ngCMatrix`, or `lgCMatrix`, depending on parameters `binary` and `logical`).
#' \item COO (a.k.a. `TsparseMatrix`) when calling `as.coo.matrix`
#' (class `dgTMatrix`, `ngTMatrix`, or `lgTMatrix`, depending on parameters `binary` and `logical`).
#' \item sparse vector (class dependant on input) when calling `as.sparse.vector`.
#' }
