magRange: magRange
Magnify the range of a variable.
Description
By default, R's range function returns the minimum and
maximum values of a variable. This returns a magnified
range. It is used for some plotting functions in the
rockchalk package
Usage
magRange(x, mult = 1.25)
Arguments
x
an R vector variable
mult
a multiplier by which to magnify the range of
the variable. A value of 1 leaves the range unchanged.
May be a scalar, in which case both ends of the range are
magnified by the same amount. May also be a two valued
vector, such as c(minMag,maxMag)
