advanced patterns when using `ggplot2` with `facet_wrap` and a custom theme in R
I'm wondering if anyone has experience with Quick question that's been bugging me - I'm running into a question when using `facet_wrap()` in `ggplot2` along with a custom theme. My plots look fine without the theme, but once I apply it, the axis labels and titles disappear completely. Here's a snippet of my code: ```r library(ggplot2) # Sample data df <- data.frame( group = rep(c('A', 'B'), each = 10), value = rnorm(20) ) # Custom theme define_custom_theme <- function() { theme_minimal() + theme( axis.title = element_text(size = 16), plot.title = element_text(size = 20) ) } # Plot with facet_wrap p <- ggplot(df, aes(x = group, y = value)) + geom_boxplot() + facet_wrap(~ group) + labs(title = 'Boxplot by Group') + define_custom_theme() print(p) ``` When I run this code, I get a plot with no axis titles and the main title is also missing. I've tried removing the custom theme to see if it works without it, and the titles show up just fine. I've also checked to ensure that my `ggplot2` package is up to date (version 3.3.5), but the scenario continues. Is there something I'm missing when applying a custom theme that could be causing this behavior? Any insights would be greatly appreciated. This is part of a larger web app I'm building. Has anyone else encountered this? Has anyone else encountered this? Any ideas how to fix this?
