:lock_with_ink_pen: Opinionated, typographic-centric ggplot2 themes and theme components

hrbrthemes : Additional Themes and Theme Components for ‘ggplot2’

This is a very focused package that provides typography-centric themes and theme components for ggplot2. It’s a an extract/riff of hrbrmisc created by request.

The core theme: theme_ipsum (“ipsum” is Latin for “precise”) uses Arial Narrow which should be installed on practically any modern system, so it’s “free”-ish. This font is condensed, has solid default kerning pairs and geometric numbers. That’s what I consider the “font trifecta” must-have for charts. An additional quality for fonts for charts is that they have a diversity of weights. Arial Narrow (the one on most systems, anyway) does not have said diversity but this quality is not (IMO) a “must have”.

The following functions are implemented/objects are exported:

Themes:

• theme_ft_rc: A precise & pristine ggplot2 theme with opinionated defaults and an emphasis on typoghraphy
• theme_ipsum: A precise & pristine ggplot2 theme with opinionated defaults and an emphasis on typography
• theme_ipsum_ps: A precise & pristine ggplot2 theme with opinionated defaults and an emphasis on typoghraphy
• theme_ipsum_rc: A precise & pristine ggplot2 theme with opinionated defaults and an emphasis on typoghraphy
• theme_ipsum_tw: A precise & pristine ggplot2 theme with opinionated defaults and an emphasis on typoghraphy
• theme_modern_rc: A precise & pristine ggplot2 theme with opinionated defaults and an emphasis on typoghraphy

Scales (that align with various themes):

• scale_color_ft: Discrete color & fill scales based on the FT palette
• scale_color_ipsum: Discrete color & fill scales based on the ipsum palette
• scale_colour_ft: Discrete color & fill scales based on the FT palette
• scale_colour_ipsum: Discrete color & fill scales based on the ipsum palette

• scale_y_comma: X & Y scales with opinionated pre-sets for percent & comma label formats
• scale_y_percent: X & Y scales with opinionated pre-sets for percent & comma label formats

Palettes/Named Colors:

• ipsum_pal: A muted, qualitative color palette
• ft_cols: FT color palette
• ft_pal: A bright qualitative color palette
• ft_text_col: FT color palette

Fonts:

• font_an: Arial Narrow font name R variable aliases

Utilities:

• flush_ticks: Makes axis text labels flush on the ends
• ft_geom_defaults: Change geom defaults from black to custom lights for the FT theme
• gg_check: Spell check ggplot2 plot labels
• import_plex_sans: Import IBM Plex Sans font for use in charts
