### ** Examples

all(M >= 1) # TRUE

[1] TRUE

any(M < 0 ) # FALSE

[1] FALSE

MN <- M; MN[2,3] <- NA; MN

3 x 4 Matrix of class "dgeMatrix"
     [,1] [,2] [,3] [,4]
[1,]    1    4    7   10
[2,]    2    5   NA   11
[3,]    3    6    9   12

all(MN >= 0) # NA

[1] NA

any(MN <  0) # NA

[1] NA

any(MN <  0, na.rm = TRUE) # -> FALSE
