Hi R people
I am trying to build a plot that includes a unicode character (The plus-minus sign U+00B1)
Here is some fake data:
set.seed(1) df <- crossing( Rated_Movement = c("Running", "Jumping"), Rater = c("John Snow", "Batman", "Hulk")) %>% mutate( Error = runif(n = 6, min = 0, max=2))
Here is my code for the plot so far:
ggplot(df, aes(x = Rated_Movement, y = Rater, fill = Error)) + geom_tile(color = "black", size = 0.5, alpha = 0.8)+ geom_text(aes(label = paste("+-", round(Error,2))))+ scale_fill_gradientn(colours = terrain.colors(10))+ theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank())
Here is the plot:
Is there a way that I can change the +- to unicode character U+00B1
I tried using the backslash to escape:
But I get the error:
"Error: '\U' used without hex digits in character string starting ""\U""
Any help will be much appreciated.
