Generate spacing for minor tick marks on a plot with log-scaled axes
Generate spacing for minor tick marks on a plot with log-scaled axes
Generates a sequence of numbers providing minor tick marks on log scaled axes.
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, 2x1, 3x1, ..., x2) to the vector of return values.
This is useful for generating spacing of minor tick-values on log-transformed axes.
