rockchalk (version 1.6.2)

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, maxMa

Examples

x1 <- c(0, 0.5, 1.0)
range(x1)
magRange(x1, 1.1)
magRange(x1, c(1.1, 1.4))
magRange(x1, 0.5)
magRange(x1, c(0.1, 0.1))
x1 <- rnorm(100)
range(x1)
magRange(x1)
magRange(x1, 1.5)
magRange(x1, c(1,1.5))
