wspviz

Utilities for common R visualization tasks at WSP Finland. Current features:

Color palettes for WSP and HSL colors

Planned features:

Tailored ggplot2 themes for WSP and other common contexts

Installation

Ensure you have devtools installed. To get the latest development version of wspviz, run the following command:

devtools::install_github("webbidevaajat/wspviz")

Current version depends on ggplot2 library (because of show_palettes() function).

Functions currently

pal_wsp(): standard WSP colors
pal_wsp2(): strong WSP colors + some ad-hoc accent colors, meant for visualizations where several distinct colors are needed
pal_hsl(): color palette defined by Helsinki Region Transport style guide

Examples

Get all the HSL colors as a named vector:

library(wspviz)
pal_hsl()

Get selected WSP colors:

library(wspviz)
pal_wsp("red", "blue", "gray")

Plot a color palette:

library(wspviz)
show_palette(pal_wsp())

NEW: a palette with basic WSP colors + a couple of roughly matching accent colors:

library(wspviz)
show_palette(pal_wsp2())

If you are for some reason running the palette functions several times, say, generating 1000 different plots, you can extract the color codes and just use named vector subsetting for a slight performance benefit (comparison has not been made so far), like this:

library(wspviz)
pal <- pal_hsl()
show_palette(pal[c("bus", "tram", "train", "metro", "ferry")])
# Instead of show_palette(pal_wsp("purple", "midnightblue"))
