## 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.

### Examples

    #Sequence suitable for log base 10 labels
    makeLogMinor(seqLog(1E-5, 1E5))
