ggrough
?ggrough
is an R package that converts your ggplot2
plots to rough/sketchy charts, using the excellent javascript roughjs
library.
library(ggplot2) count(mtcars, carb) %>% ggplot(aes(carb, n)) + geom_col() + labs(title="Number of cars by carburator count") + theme_grey(base_size = 16) -> p p
library(ggrough) options <- list( Background=list(roughness=8), GeomCol=list(fill_style="zigzag", angle_noise=0.5, fill_weight=2)) get_rough_chart(p, options)
install.packages("devtools") # if you have not installed "devtools" package devtools::install_github("xvrdm/ggrough")
Call get_rough_chart()
, using your ggplot2 chart as the first argument. See this page for more ggrough examples and all the available options to customize your output.
ggrough
is a work in progress and still has big bugs. Contributions are welcome!
ggrough
works "ok" with RStudio Viewer. However you need to redraw your chart everytime you change the size of the Viewer tab and the charts will redraw when you try to copy it via Export -> Save As Image
. The latter can be annoying since some roughjs
settings can add a lot of randomness.
ggrough
doesn't work well with Rmarkdown files yet. For example, it can only generate one chart per document. If you have multiple charts it overlays them on top of each other.
ggrough
is an htmlwidget. It converts your ggplot2
chart to SVG using the package svglite
then parse the different elements (<rect>
, <path>
, <circle>
...) to create a chart in a HTML Canvas element^[roughjs
can also render to SVG. This will be supported by ggrough
in the future] with roughjs
.
An article explaining how ggrough
works is in the making, to help potential contributors get started.
This package is only possible thanks to the massive work of:
htmlwidget
and ggplot2
.roughjs
.ggplot2
.svglite
