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?

Excuse my brevity, but take a look at ?plotmath It has tons of tips for making pretty labels On Tue, Nov 30, 2021, 14:05 Rich Shepard <rshepard at appl-ecosys.com> wrote:> 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 > > ______________________________________________ > R-help at r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >[[alternative HTML version deleted]]
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.
