Add a layer to a pmx_vpc_plot with a facet warning

S3 method for + applied to objects returned by plot_vpc_cont(), plot_vpc_cens(), and plot_build_vpc(). Delegates to the standard ggplot2 + operation for all layer types. When e2 is a ggplot2::facet_wrap() or ggplot2::facet_grid() specification, a warning is issued because the VPC summary statistics are pre-computed and will not reflect the added stratification. Use strat_var in plot_vpc_cont(), plot_vpc_cens(), or df_vpcstats() to stratify both statistics and panels.

Facets inside a list() are caught the same way. restyle_plot() and reveal() keep the pmx_vpc_plot class, and reveal(as = "facet") and restyle_plot(facet = ) warn like + facet_*().

The pmx_vpc_plot class is preserved on the result so that subsequent + calls are also intercepted.

Usage

# S3 method for class 'pmx_vpc_plot'

restyle_plot(p, ...)

# S3 method for class 'pmx_vpc_plot'
reveal(p, col, ..., as = NULL, on = NULL)

Arguments

col, as, on, ...

Passed to the ggstylekit reveal() or restyle_plot() method.

Value
