Hi all,
I m trying to write the following text on an axis on a ggplot2 graph and
I can t make it work. Worse, any advice in blogs I found, is not explained
and therefore I can t
work out how the successful solutions to other users work. Can someone
help and provide a documentation of the symbols they use? Here is what I
want to type, the "+"
"Percentage of CD45+ cells"
Thanks,
Theo

Thanks Brandon. So to understand, " " is for normal text, ~ connects text
and { } is used for what exactly?

The documentation you're looking for is ?plotmath in an interactive R
session, or https://stat.ethz.ch/R-manual/R-devel/library/grDevices/html/plotmath.html
.

It doesn't actually document the effect of `a ~ b`, only `a ~~ b`, but
I believe you are correct that `a ~ b` draws a and b with a normal
space between (`a ~~ b` is described as drawing a and b with *extra*
space between).

{ } are "invisible grouping". The example given is `x^{y + z}` places
the entire expression `y + z` in the superscript of x. I get the same
result with
"Percentage of"~"CD45"^{"+"}~"Cells" as with "Percentage
of"~"CD45"^"+"~"Cells", so perhaps Marios is just in the habit of
always writing ^{...} whether or not the curly braces are necessary.

~ is used to replace the character for space.

I had a similar issue recently :)
