A continuous ggplot scale for count data with sane defaults for breaks.
It uses base::pretty() to increase the default number of breaks and prefers 5er breaks.
Additionally, the first tick (i.e. zero) is aligned to the lower left corner.

A ggplot2 scale object that can be added to a plot.
The name of the scale. Used as the axis or legend title. If
waiver(), the default, the name of the scale is taken from the first
mapping used for that aesthetic. If NULL, the legend title will be
omitted.
Target number of breaks passed to base::pretty(). Defaults to 8.
Minimum number of breaks passed to base::pretty(). Defaults to 5.
The "5-bias" parameter passed to base::pretty(); higher values
push the breaks more strongly toward multiples of 5. Defaults to 4.
Uses own expansion logic. Use expand = waiver() to restore ggplot defaults
or ggplot2::expansion() to modify
One of:
NULL for no labels
waiver() for the default labels computed by the
transformation object
A character vector giving labels (must be same length as breaks)
An expression vector (must be the same length as breaks). See ?plotmath for details.
A function that takes the breaks as input and returns labels as output. Also accepts rlang lambda function notation.
One of:
NULL to use the default scale range
A numeric vector of length two providing limits of the scale.
Use NA to refer to the existing minimum or maximum
A function that accepts the existing (automatic) limits and returns
new limits. Also accepts rlang lambda function
notation.
Note that setting limits on positional scales will remove data outside of the limits.
If the purpose is to zoom, use the limit argument in the coordinate system
(see coord_cartesian()).
One of:
Function that handles limits outside of the scale limits (out of bounds). Also accepts rlang lambda function notation.
The default (scales::censor()) replaces out of
bounds values with NA.
scales::squish() for squishing out of bounds values into range.
scales::squish_infinite() for squishing infinite values into range.
Missing values will be replaced with this value.
For continuous scales, the name of a transformation object or the object itself. Built-in transformations include "asn", "atanh", "boxcox", "date", "exp", "hms", "identity", "log", "log10", "log1p", "log2", "logit", "modulus", "probability", "probit", "pseudo_log", "reciprocal", "reverse", "sqrt" and "time".
A transformation object bundles together a transform, its inverse,
and methods for generating breaks and labels. Transformation objects
are defined in the scales package, and are called transform_<name>. If
transformations require arguments, you can call them from the scales
package, e.g. scales::transform_boxcox(p = 2).
You can create your own transformation with scales::new_transform().
For position scales, The position of the axis.
left or right for y axes, top or bottom for x axes.
sec_axis() is used to specify a secondary axis.
A function used to create a guide or its name. See
guides() for more information.
Additional arguments passed on to base::pretty().
