National Road Safety Observatory (ONSV) Style for 'ggplot2' Graphics.
onsvplot
The goal of onsvplot
is to provide ggplot theme and color elements to help create graphics in the style of the National Observatory for Road Safety.
Overview
This package provides two main functions and a palette of colors:
theme_onsv()
: Apply the ONSV theme to a ggplot object;scale_discrete_onsv()
: Apply the ONSV color palette to a ggplot object;onsv_palette
: A data object which provides the full palette of colors, including its hex codes.
Installation
You can install the development version of onsvplot
like so:
remotes::install_github("pabsantos/onsvplot")
Or the CRAN version:
# install.packages("onsvplot")
Example
This is a basic example which shows you how to apply the functions included in this package. First, a basic ggplot graphics:
library(onsvplot)
library(ggplot2)
plot1 <- ggplot(data = iris, aes(
x = Sepal.Length, y = Sepal.Width, color = Species
)) +
geom_point()
plot1
Then, apply theme_onsv()
to change the theme of the plot and scale_discrete_onsv()
to change the colors:
theme_set(theme_onsv())
plot1 + scale_discrete_onsv()
If only one color is necessary in the plot, it is possible to use one of the colors included in the onsv_palette
object;
str(onsv_palette)
#> List of 12
#> $ blue : chr "#00496d"
#> $ yellow : chr "#f7951d"
#> $ red : chr "#d51f29"
#> $ green : chr "#1fa149"
#> $ pink : chr "#ec0d6b"
#> $ orange : chr "#f05f22"
#> $ lightblue : chr "#99B6C5"
#> $ lightyellow: chr "#FCD5A5"
#> $ lightred : chr "#EEA5A9"
#> $ lightgreen : chr "#A5D9B6"
#> $ lightpink : chr "#F79EC4"
#> $ lightorange: chr "#F9BFA7"
applying directly to the color
or fill
of the geom:
ggplot(data = iris, aes(x = Sepal.Length, y = Sepal.Width)) +
geom_point(color = onsv_palette$yellow)
