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?
