The 'NA' label is not displayed on axis.text with element_markdown() #121
Description
ggtext() modifies ggplot's default behavior, which is to display the label 'NA' in axis texts.
For example:
library(tidyverse)
library(ggtext)
tibble(
group = c("group1", "group2", "group3", NA, "**total**"),
value = c(-0.5, 0.5, 2, 3, 2)
) %>%
ggplot(aes(value, group)) +
geom_col(alpha = 0.5, fill = "purple") +
theme(
axis.text.y = element_markdown()
)
VS
tibble(
group = c("group1", "group2", "group3", NA, "**total**"),
value = c(-0.5, 0.5, 2, 3, 2)
) %>%
ggplot(aes(value, group)) +
geom_col(alpha = 0.5, fill = "orange2")
Is there any way to change element_markdown()'s behavior so that it displays the 'NA' label without first transforming the missing NA value into a string modality “NA”? The way ggplot handles NAs by default is very useful to me (automatic color, etc), and using ggtext() then requires major transformations in my functions.
Thank you!
