Your Turn
Adjust the code below, using ggtext to make the word ‘plastic’ bold in the title and wrapping the subtitle so it is multi-line.
library(tidyverse)
library(ggtext)
##Your turn
#Use ggtext to make the word 'plastic' bold in the title
#and wrap the subtitle so it is multi-line
plastics <- readr::read_csv('https://raw.githubusercontent.com/rfordatascience/tidytuesday/master/data/2021/2021-01-26/plastics.csv')
plastics %>%
group_by(year) %>%
summarize(total = sum(grand_total, na.rm = TRUE)) %>%
ggplot() +
geom_bar(aes(x = "", y = total, fill = as.character(year)), stat = "identity", width = 1) +
coord_polar("y", start = 0) +
theme_minimal() +
labs(title = "Plastic pollution, by year", fill = "",

Can i not use the same approach to create a multiline subtitle for a combination of plots using patchwork? It throws the following error
"Error: gridtext has encountered a tag that isn't supported yet: Only a very limited number of tags are currently supported. "

combined + plot_annotation(title = "Plastic pollution in India in 2019 and 2020 ", subtitle = "Data available at https://brandaudit.breakfreefromplastic.org",
theme(plot.tag = element_text(size = 10), plot.title = element_textbox_simple(), plot.subtitle = element_textbox_simple() )

The
ggtextonly uses a small set of HTML tags (e.g. italics, bold). I can't see your full code so I don't know exactly what's going on, but I'm guessing you tried to use some HTML that isn't supported (e.g. a link). Does that seem like it might be what's going on?
