makeLogMinor: Generate spacing for minor tick marks on a plot with log-scaled axes

Description

Generates a sequence of numbers providing minor tick marks on log scaled axes.

Usage

makeLogMinor(major)

Arguments

major

a vector of values giving major tick marks.

Details

A vector is created according to the following algorithm. For each pair of adjacent values (x1, x2) in major, the function adds the values (x1, 2*x1, 3*x1, ..., x2) to the vector of return values.

This is useful for generating spacing of minor tick-values on log-transformed axes.
