date_*_breaks does not return breaks, but a function that calculates
breaks. This is for compatibility with the breaks functions from scales
such as scales::pretty_breaks(), and for ease of use with ggplot2.
Usage
date_yq_breaks(n = 6)
date_ym_breaks(n = 6)
date_yw_breaks(n = 6)
Value
a function that calculates a maximum of n breaks for a date_xx
vector
Arguments
n
NULL or integer scalar. The desired maximum number of breaks.
The breaks algorithm may choose less breaks if it sees fit.
