Changing plot titles and font size possible?

[foxtrotduck]

When using draw for a multi-plot gam, is it possible to change the name of the variables (e.g., from "air_press" to "Air Pressure") and/or change font size for the plots? See plot below created with

model <- gam(data = data, var ~ s(air_press, k = 4) + 
                      s(turb, k = 4)...
draw(model)

The font size is controlled through the theme, which is standard ggplot stuff. Just remember to use the & operator when you modify the theme so that is applies to all plots in the patchwork

draw(m) & theme_grey(base_size = 9)

for example would set the base font size to 9 points, while still using the default theme.

As for the titles, axis labels, no, that's not something that can be changed. If you want full control, using

smooth_estimates(m, smooth = "s(air_press)") |>
  draw(xlab = "Air Pressure", title = "s(Air Pressure)")

for more control and

smooth_estimates(m, smooth = "s(air_press)") |>
  add_confint() |>
  ggplot(....)

for complete control. You can save those plots and then combine them into a patchwork using wrap_plots().

I could look into allowing the user to pass a vector of titles for the plots, but that is not high on my priority list.
