Formatter not using styler?

I might have something wrong with my config but I can't figure out what. I am using vscode with the R extension using the languageserver. R is configured correctly (I think) such that I can run scripts, view plots, etc. Linting works as well.

Formatting does not seem to run through the styler package as expected.

Here is a file before formatting:

library("tidyverse")

tibble(x = 1:12, y = rnorm(12)) %>%
ggplot(aes(x = x, y = y)) +
geom_point() +
geom_smooth(method = "lm")
c(1,2,3)

And after formatting using the languageserver functionality in vscode (Right click > Format Document):

library("tidyverse")

tibble(x = 1:12, y = rnorm(12)) %>%
    ggplot(aes(x = x, y = y)) +
    geom_point() +
    geom_smooth(method = "lm")
c(1, 2, 3)

As you can see, the lack of spaces in the last line is fixed. However, the indentation is using 4 spaces, not 2 spaces. The linter yells at me because of the wrong number of spaces.

If I use styler directly on the file (i.e. by opening an R terminal, and running the command style_file("/path/to/file.R")), I get the following:

library("tidyverse")

tibble(x = 1:12, y = rnorm(12)) %>%
  ggplot(aes(x = x, y = y)) +
  geom_point() +
  geom_smooth(method = "lm")
c(1, 2, 3)

In this case, the indentation is correct.

Any advice?

Start by reproducing formatting through the R languageserver in VSCode and compare its output with running styler directly on the same file. Done means the languageserver formatter uses styler-compatible two-space indentation so the formatted code no longer triggers the linter.
