max(..., na.rm=TRUE) min(..., na.rm=TRUE) pmax(..., na.rm=FALSE) pmin(..., na.rm=FALSE)
max and min return the maximum or minimum of all the values
present in their arguments.
If na.rm is FALSE an NA value in any
of the arguments will cause a value of NA to be returned,
otherwise NA values are ignored.
pmax and pmin take several vectors as arguments and return a
single vector giving the parallel maxima (or minima) of the vectors.
The first element of the result is the maximum (minimum) of the first
elements of all the arguments, the second element of the result is the
maximum (minimum) of the second elements of all the arguments and so on.
Shorter vectors are recycled if necessary. If na.rm is FALSE,
NA values in the input vectors will produce NA values in the
output. If na.rm is TRUE, NA values are ignored.
