compute_timeline_label: Function to compute data to be consumed by...

In wingtham/NOAA: Read, Cleanse and Visualise NOAA Dataset

Description

The function filters the data according to date. It returns data that are in between xmin and xmax. Note that xmin and xmax can either be mapped (using aes(xmin=???)) or being an argument to geom_timeline. If both are specified, the mapped value will be considered. In addition, if n_max and byCol are specified, only n_max rows orderd by byCol are returned. If no byCol is specified, it returns n_max rows randomly.

Usage

compute_timeline_label(data, scales, n_max = NA, ...)

Arguments

data	data frame passed from stat / geom
scales	passed from stat/ geom
xmin	date passed from stat / geom, specifying the minimum date to be considered
xmax	date pased from stat /geom, specifying the maximum date to be considered

Value

data frame to be consumed by geom
