Lifecycle: experimental R-CMD-check Codecov test coverage
ggfx is a (currently experimantal) package that allows the use of various filters and shaders on ggplot2 layers.
You can install ggfx from CRAN in the usual manner
(install.packages('ggfx')) or you can grab the development version
directly from github using the devtools package:
# install.packages('devtools') devtools::install_github('thomasp85/ggfx')
The basic API of ggfx is to provide a range of with_*() modifier
functions instead of special versions of common geoms. This means that
ggfx will work with any geom from ggplot2 and the extension packages (I
think...). An example showing some of the different functionalities are
given below. Note that the output is produced with regular geoms.
library(ggplot2) library(ggfx) ggplot() + as_reference( geom_polygon(aes(c(0, 1, 1), c(0, 0, 1)), colour = NA, fill = 'magenta'), id = "displace_map" ) + with_displacement( geom_text(aes(0.5, 0.5, label = 'ggfx-ggfx'), size = 25, fontface = 'bold'), x_map = ch_red("displace_map"), y_map = ch_blue("displace_map"), x_scale = unit(0.025, 'npc'), id = "text" ) + with_blend( geom_density_2d_filled(aes(rnorm(1e4, 0.5, 0.2), rnorm(1e4, 0.5, 0.2)), show.legend = FALSE), bg_layer = "text", blend_type = "in", id = "blended" ) + with_shadow("blended", sigma = 3) + coord_cartesian(xlim = c(0, 1), ylim = c(0, 1), clip = 'off') + labs(x = NULL, y = NULL)
