Range of Data

DESCRIPTION:

Returns the minimum and the maximum of all of the elements of all of the arguments.

USAGE:

range(..., na.rm=F) 

REQUIRED ARGUMENTS:

...
numeric objects. Missing values ( NAs) are allowed.

OPTIONAL ARGUMENTS:

na.rm=
logical flag: should missing values be removed before computation? This argument must be specified in the na.rm= form.

VALUE:

vector of two elements, the first is the minimum of all the elements of all the arguments; the second is the maximum. Any NAs in the input result in NAs in the output unless na.rm=TRUE.

DETAILS:

This is part of the Summary group of generic functions -- see Methods.

This function is useful as an argument to plotting when it is desired to specify the limits for the x- or y-axes. (See the plot example.)

EXAMPLES:

plot(x, y, ylim=range(y, 0, 1)) # force y-axis to include (0, 1) 
diff(range(x)) # distance between max and min
