applying a theme

[nicholasjhorton]

Do you have any guidance about what I'm doing wrong here? I was hoping to move to a black and white theme with this plot:

library(ggformula)
#> Loading required package: ggplot2
#> Loading required package: ggstance
#> 
#> Attaching package: 'ggstance'
#> The following objects are masked from 'package:ggplot2':
#> 
#>     geom_errorbarh, GeomErrorbarh
#> Loading required package: scales
#> Loading required package: ggridges
#> 
#> New to ggformula?  Try the tutorials: 
#>  learnr::run_tutorial("introduction", package = "ggformula")
#>  learnr::run_tutorial("refining", package = "ggformula")
gf_point(pcs ~ age, color = ~ homeless, data = mosaicData::HELPrct) |>
  gf_theme(theme_bw())

You do have a black and white theme (theme_bw()), but the theme in ggplot2 doesn't handle the colors of the data. It's the scales that do that job. The theme covers things like the axes, title, other labeling, etc.

So it is a bit confusing, I guess. But this is doing what ggplot2 says it should do.

Here's an example of using a grey-scale color scale:

suppressPackageStartupMessages(library(ggformula))
gf_point(pcs ~ age, color = ~ homeless, data = mosaicData::HELPrct) |>
  gf_theme(theme_bw()) |>
  gf_refine(scale_color_grey())

You could also use scale_color_manual() and select your own colors.
