## "Matrix" Methods for Functions all() and any()

### Description

The basic R functions `all` and `any` now have methods for `Matrix` objects and should behave as for `matrix` ones.

### Methods

all
  `signature(x = "Matrix", ..., na.rm = FALSE)`: ...
any
  `signature(x = "Matrix", ..., na.rm = FALSE)`: ...
all
  `signature(x = "ldenseMatrix", ..., na.rm = FALSE)`: ...
all
  `signature(x = "lsparseMatrix", ..., na.rm = FALSE)`: ...

### Examples

    M <- Matrix(1:12 +0, 3,4)
    all(M >= 1) # TRUE
    any(M < 0 ) # FALSE
    MN <- M; MN[2,3] <- NA; MN
    all(MN >= 0) # NA
    any(MN <  0) # NA
    any(MN <  0, na.rm = TRUE) # -> FALSE
