Re: [R] Degree symbol as axis label superscript
Yes, but I should acknowledge my ignorance in not realizing that "\u00b0"
(hex 176) is a simpler way to get the character in R without the OS tool
than intToUtf8() . If you need math notation beyond simple symbol
characters, plotmath is certainly indispensable.

Re: [R] Degree symbol as axis label superscript
Using the degree character seems perfectly legit to me. The reason I
suggest looking at plotmath is that I think plotmath is easier to read
(that is, if you're escaping your characters with \u), and because for
anything more complicated like set notation, big sums, integrals, you'll
need to get used to plotmath to make your labels. Either way, nice
suggestion, both work perfectly well for this situation

Re: [R] Degree symbol as axis label superscript
one of my solution :
text(x,y,"\u00B0C", cex=1.1, font=2)
it will produce "°C"
text(x,y,"\u00B3C", cex=1.1, font=2)
it will produce "superscript(3)C"
so basically change the character after the "\u00B..." will produce
the superscript.
Best, Ani

David,
Absolutely nothing. When there's no specific degree value in the label
because the axis represents a range of values there's no digit preceeding
the ^ symbol.
The axis label is 'Temperature (oC)' with the degree symbol preceeding a
character, not following a specific digit.
There's nothing special about following a digit. You can have it follow
anything. Since you were going to need to quote the parentheses anywa,
then have it superscripted above the level of the paren:
plot(1,1, ylab = expression(Temperature~"("^degree*C*")") )

Re: [R] Degree symbol as axis label superscript
True, but unnecessary with UTF-8 encodings of unicode (subject to some
caveats, though):
plot(1:5, runif(5),xlab = "Temp (°F)", ylab = "result")
should work fine, where the º ("degree") symbol was inserted by the
symbol insertion facility on my Mac. Windows has something similar.
See the comments in the plotmath documentation just before the
examples for more details on this, along with some caveats about the
need for a suitable display/plot device.
More laboriously, but perhaps more informatively, one can look up
"unicode code point for degree symbol" to find that it is decimal 176.
Then R's intToUtf8() function converts this to the UTF-8 encoding that
**should** display as a "degree" symbol, subject to the above
referenced caveats.
Hence:
> intToUtf8(176)
[1] "°" ##degree character
## So, for example, you can do:
> degrF <-paste0(intToUtf8(176),"F")
> degrF
[1] "°F" ("degrees F")
> plot(1:5, runif(5),xlab = paste0("Temp (", degrF,")"), ylab = "result")
As Andrew said, you can use plotmath to do this, too; it just isn't
needed for simple insertion of "standard" symbols.
NOTE: As I am far from an expert on all of this, I would appreciate
clarification or correction of any errors or misstatements in the
above.

Re: [R] Degree symbol as axis label superscript [RESOLVED]
I think you have to not put the word degree in quotes, something like:
graphics::plot(
x = 1,
xlab = quote(
32 * degree
)
)
works for me, though yours seems like a good solution too

[R] Degree symbol as axis label superscript
I want to present the temperature on the Y-axis label as 'Water Temperature
(oC)' with the degree symbol as a superscript.
My web search found a couple of methods; one put the entire example string
in the axis label, the other is close, but still incorrect.
Source example:
#define expression with superscript
x_expression <- expression(x^3 ~ variable ~ label)
# The example axis label is:
'X3 variable label' (with the 3 as a superscript)
My use:
# Set degree symbol as superscript in plot's y axis:
y_expression <- expression(^o ~ C)
R's error message:
Error in source("../scripts/all_temp_plots.r") :
../scripts/all_temp_plots.r:10:28: unexpected '^'
9: # Set degree symbol as superscript in plot's y axis:
10: y_expression <- expression(^
^
What is the proper way to display a degree symbol in a plot's axis label?
Rich
