getRange: Function for rounding and/or segmenting a range.

Description

Function for rounding and/or segmenting a range.

Usage

getRange(x, dec = NULL, step = NULL, n.seg = 2)

Arguments

x

A numeric vector.

dec

Number of decimal points for rounding using function round. Applied after argument step. If NULL (default), no rounding is applied.

step

Round the

n.seg

Numeric value, number of values in the equally spaced sequence. Default is 2 (min, max).

Value

vector, range of equally spaced sequence.

Examples

# NOT RUN {
zlim <- c(-2.5, 3.01)
# does not change anything:
getRange(zlim)
# create a range of 5 numbers: 
# (basically just using seq )
getRange(zlim, n.seg=5)
# rounds the numbers:
getRange(zlim, dec=0)
getRange(zlim, n.seg=5, dec=0)
# extreme values are multiplications of 5
# that contains zlim values:
getRange(zlim, step=5)
getRange(zlim, step=5, n.seg=5)
# similar, but not the same:
getRange(zlim, n.seg=5, dec=0)
getRange(zlim, n.seg=5, step=1)
# combining:
getRange(zlim, n.seg=5, step=1, dec=0)

# }
