Get axis label for minorLogTicks

Description

Get axis label for minorLogTicks

Usage

getAxisLabel(
  i,
  asValues,
  logAxisType = c("normal", "flip", "pvalue"),
  logBase,
  base_limit = 2,
  offset = 0,
  symmetricZero = (offset > 0),
  ...
)

Arguments

i	numeric axis value
asValues	logical indicating whether the value should be evaluated.
logAxisType	character string with the type of axis values: "normal": axis values as-is. "flip": inverted axis values, for example where negative values should be displayed as negative log-transformed values. "pvalue": for values transformed as -log10(pvalue)
logBase	numeric logarithmic base
base_limit	numeric value indicating the minimum value that should be written as an exponential.
offset	numeric value of offset used for log transformation.
symmetricZero	logical indicating whether negative values should be displayed as negative log-transformed values.
...	additional arguments are ignored.

Details

This function is intended to be called internally by jamba::minorLogTicks().
