Vectorised Min and Max Operators

Vectorised infix functions implementing pmin() and pmax().

Usage

x %:<% y

x %>:% y

Arguments

x, y

numeric or character arguments (see Note).

Value

A vector of length the longest of the input vectors as returned by pmin() and pmax(), or of length zero if one of the inputs had zero length.

Details

The vectorised infix functions %:<% and %>:% may be useful in implementing pmin() and, pmax() and was inspired by the null coalescing operator %||%.

Note

‘Numeric’ arguments are vectors of type integer and numeric, and logical (coerced to integer). For historical reasons, NULL is accepted as equivalent to integer(0).

pmax and pmin will also work on classed S3 or S4 objects with appropriate methods for comparison, is.na and rep (if recycling of arguments is needed).

Examples

1:10 %:<% 10:1
#>  [1] 1 2 3 4 5 5 4 3 2 1
c(1:9, NA) %:<% c(NA, 9:1)
#>  [1] NA  2  3  4  5  5  4  3  2 NA

1:10 %>:% 10:1
#>  [1] 10  9  8  7  6  6  7  8  9 10
c(1:9, NA) %>:% c(NA, 9:1)
#>  [1] NA  9  8  7  6  6  7  8  9 NA
