Parse the log-axis arguments of a mizer plot function

Internal helper that resolves the various ways of specifying which axes should use a logarithmic scale into a consistent pair of logical flags. It is exported so that extension packages (such as mizerMR) can reuse it in their own array plot() methods.

Usage

parsePlotLog(log, log_x = FALSE, log_y = FALSE)

Arguments

log

Either NULL, a single logical (legacy form, toggling only the y-axis), or a character string containing only the letters "x" and/or "y" to indicate which axes should be logarithmic.

log_x, log_y

Default logical flags used when log is NULL.

Value

A list with logical components log_x and log_y.
