awtools

A simple, distilled, #rstats theme used mainly on www.austinwehrwein.com

devtools::install_github('awhstin/awtools')

The main theme is the a_plex_theme which the fonts are available from Google Fonts:

• IBM Plex Mono (plot title, legend)
• IBM Plex Sans (subtitle, captions, axis_text)

a_dark_theme shares mostly all the same elements of the main theme but the colors are adjusted to make a dark theme.

Palettes

pal.bands(ppalette,mpalette,spalette,gpalette,bpalette,labels = c('Primary','Flat','Secondary','Gray','Big'))

Examples

a_plex_theme features: - grid: [TRUE/FALSE] turns off the main panel grids. - noaxis: [TRUE/FALSE] turns off the axis of the plot, seen mainly in maps. - emphasis: [‘x’,‘y’,‘xy’] adds a bold to an axis title for emphasis.

All examples are made using the gcookbook package. Let's start with an example using the a_plex_theme with the a_flat_color palette.

ggplot(heightweight,aes(x=heightIn,y=weightLb, color = factor(round(ageYear)))) + 
  geom_point() +
  a_plex_theme() +
  a_flat_color() +
  labs(
    title='Height and Weight',
    subtitle='Sample data of height inches and weight in pounds.',
    caption='Source: R Graphics Cookbook',
    color='Age'
  )

Example of a_dark_theme with the primary color palette.

ggplot(mtcars, aes(mpg, wt)) +
  geom_point(aes(color=factor(carb), size=drat)) +
  labs(x="Fuel efficiency (mpg)", y="Weight (tons)",
       title="Basic scatterplot example",
       subtitle="A demonstration",
       caption="This be a caption") + 
  a_primary_color() +
  a_dark_theme()

And a new a_gray_color and a_gray_palette which is a simple four color grays palette.

lax<-read_csv('https://raw.githubusercontent.com/awhstin/temperaturesv2/master/LAX-NCDC-2015-18.csv') %>% 
  filter(months(DATE)=='January')%>%
  mutate(year=format(DATE,'%Y'),
         month=factor(months(DATE), levels=rev(month.name)))

## Parsed with column specification:
## cols(
##   STATION = col_character(),
##   NAME = col_character(),
##   DATE = col_date(format = ""),
##   AWND = col_double(),
##   PGTM = col_logical(),
##   PRCP = col_double(),
##   SNOW = col_logical(),
##   SNWD = col_logical(),
##   TAVG = col_double(),
##   TMAX = col_double(),
##   TMIN = col_double(),
##   WDF2 = col_double(),
##   WDF5 = col_double(),
##   WSF2 = col_double(),
##   WSF5 = col_double()
## )

ggplot(lax, aes(x=TAVG, y=month, fill=year)) +
  geom_density_ridges(scale=.9, color=NA) +
  a_plex_theme(grid=FALSE) +
  a_gray_fill()

Old

The original a_theme uses fonts that can be found and downloaded from Google Fonts:

• Roboto (plot title, legend)
• Open Sans (subtitle, captions, axis_text)

The new a_robot_theme uses fonts that can be found and downloaded from Google Fonts:

• Roboto Slab (plot title, legend)
• Roboto Light (subtitle, captions, axis_text)

The new a_concert_theme uses fonts that can be found and downloaded from Google Fonts:

• Concert One (plot title, axis_title)
• Inconsolata (subtitle, captions, axis_text)

Here is a simple scatterplot with the original a_theme.

ggplot(heightweight,aes(x=ageYear,y=heightIn, color=sex))+
  geom_point()+
  a_theme()+
  a_scale_color() +
  labs(title='Height by Age',
       subtitle='Sample data of height in inches by age in years.',
       caption='Source: R Graphics Cookbook')

a_robot_theme gets the name from the use of Roboto and Roboto Slab for the base and plot title fonts.

ggplot(heightweight,aes(x=heightIn,y=ageYear, color = factor(round(ageYear)))) + 
  geom_point() +
  a_robot_theme() +
  a_flat_color() +
  labs(
    title='Height and Age',
    subtitle='Sample data of height inches and age in years.',
    caption='Source: R Graphics Cookbook',
    color='Age'
  )

The a_concert_theme was developed for a more editorial style visualization.

ggplot(climate,aes(x=Year,y=climate$Anomaly10y, color=Source)) + 
  geom_line(size=.75) +
  a_concert_theme() +
  a_primary_color() +
  labs(
    title='Temperature Anomaly',
    subtitle='Anomaly in Celsius, smoothed over ten years',
    caption='Source: R Graphics Cookbook',
    y='Anomaly'
  )
