DHSC Colours R package

Features

• DHSC branded powerpoint template for rmarkdown.
• Approved colour codes for DHSC outputs.
• Colourblind friendly options
• ggplot theme for consistant outputs
• ggplot fill and colour scales using dhsc branding colours.
• Shortcut function remove y axis padding so intercept can be 0.
• DHSC_table function for left aligned tables in markdown.

Installation

Install using remotes:

remotes::install_github("https://github.com/DataS-DHSC/DHSCcolours")

Branded powerpoint template

Installing this package will install the template for a DHSC branded powerpoint in rmarkdown. Accessed from within rstudio via: File > New File > R Markdown > From Template > DHSC Powerpoint

Colour Codes

The function dhsc_colours() will return a named list of the approved colours. Each individual colour can also be called by it’s helper function. For example: dhsc_dark_blue(). There are approved shades of black, white and grey, which are retrieved via dhsc_bw()

Having access to the individual colour codes like this will allow users to quickly format whatever vizualisation library they are using to align with the DHSC palette.

Colourblind friendly palettes

Three and four colour accesible pallets have been hard coded into this package. You can retrieve the colour selections with DHSC_accessible_3() and DHSC_accessible_4(). Or you can use them directly with your ggplots via

dhsc_accessible_scales().

ggplot theme

There is a ggplot theme which you can include with any ggplot to standardise on a consistant aesthetic. The theme is accessed via theme_dhsc() and can be included in any ggplot with +theme_dhsc()

ggplot colour and fill scales

There are also some colour scales which you can + on to a ggplot object to recolour it with DHSC colours. There are separate scales for continuous and discrete variables.

Shortcut to set y axis intercept to 0.

By default, ggplot adds a 5% padding to your data when creating a y axis, this is to ensure that your data don't sit directly on the axis line. However it is not always desirable, e.g. with bar plots. Adding +zero_y_padding() to your ggplot objects will remove the padding, improving the way some plots appear.

DHSC tables

By default, numeric columns in rmarkdown can appear right aligned (excel style). The DHSC_table() function removes this behaviour and aligns all table text to the left.
