geom_timelinelabel: Adding labels to a geom_timeline layer

In mkaywins/Capstone_project: Capstone: Package for NOAA data

Description

Adding labels to a geom_timeline layer

Usage

geom_timelinelabel(mapping = NULL, data = NULL, stat = "identity",
  position = "identity", na.rm = FALSE, show.legend = NA,
  inherit.aes = TRUE, ...)

Arguments

mapping	aesthetic mappings
data	data to be visualized by the geom
stat	character. The statistical transformation to use on the data for this layer, as a string
position	character. Position adjustment, either as a string, or the result of a call to a position adjustment function
na.rm	logical. variable to indicate if NAs should be removed from the data
show.legend	logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes. It can also be a named logical vector to finely select the aesthetics to display.
inherit.aes	logical. If FALSE, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification.
...	Other arguments passed on to the layer

Value

Returns a layer, a combination of data, stat and geom objects including labels for certain data-points.
