Displaying a Greater Than or Equal Sign

Displaying a greater than or equal sign

An alternative to using expressions is Unicode characters, in this case Unicode Character 'GREATER-THAN OR EQUAL TO' (U+2265). Copying @mnel's example

.d <- data.frame(a = letters[1:6], y = 1:6)

ggplot(.d, aes(x=a,y=y)) + geom_point() + 
    scale_x_discrete(labels = c(letters[1:5], "\u2265 80"))

Unicode is a good alternative if you have trouble remembering the complicated expression syntax or if you need linebreaks, which expressions don't allow. As a downside, whether specific Unicode characters work at all depends on your graphics device and font of choice.

Displaying greater than sign in ggsurvplot (unicode errrors)

Per @JosefZ's suggestion, I utilized the right arrowhead unicode to generate and it worked great. Final code with solution incorporated is below:

kmcurve_pd <- ggsurvplot(km_fitp1_pd, 
              palette = c("#202960", "#8CC63E"), 
              xlab = "Time (Months)", 
              legend.labs = c(paste0("\u2264","1 Prior Progression"), 
                  paste0("\u02C3","1 Prior Progression"))

What do and stand for?

< stands for the less-than sign: <
> stands for the greater-than sign: >
≤ stands for the less-than or equals sign: ≤
≥ stands for the greater-than or equals sign: ≥
