tinyplot_add – tinyplot

Add new elements to the current `tinyplot`

Description

This convenience function grabs the preceding tinyplot call and updates it with any new arguments that have been explicitly provided by the user. It then injects add=TRUE and evaluates the updated call, thereby drawing a new layer on top of the existing plot. plt_add() is a shorthand alias for tinyplot_add().

Usage

tinyplot_add(...)

plt_add(...)

Arguments

… All named arguments override arguments from the previous calls. Arguments not supplied to tinyplot_add remain unchanged from the previous call.

Value

No return value, called for side effect of producing a plot.

Limitations

tinyplot_add() works reliably only when adding to a plot originally created using the tinyplot.formula method with a valid data argument. We cannot guarantee correct behavior if the original plot was created with the atomic tinyplot.default method, due to potential environment mismatches. (An exception is when the original plot arguments—x, y, etc.—are located in the global environment.)
Automatic legends for the added elements will be turned off.

Examples

library("tinyplot")

tinyplot(Sepal.Width ~ Sepal.Length | Species,
  facet = ~Species,
  data = iris)

tinyplot_add(type = "lm") ## or : plt_add(type = "lm")

## Note: the previous function is equivalent to (but much more convenient
## than) re-writing the full call with the new type and `add=TRUE`:

# tinyplot(Sepal.Width ~ Sepal.Length | Species,
#          facet = ~Species,
#          data = iris,
#          type = "lm",
#          add = TRUE)
