[R] degree C symbol in a function

[Daisy Englert Duursma]

Hello help,

I have changed around some graphing code and made it into a function.
Previously they y label of the axis was inserted as text in its own
layout box.

text(1,1, expression(~degree~C),cex=1)

This worked great and resulted in the symbol for degree.

In the function, I have changed it so:

text(1,1,paste(b_unit),cex=1)

and

b_unit<-expression(~degree~C)

This now inserts ~degree~C instead of the symbol.


Any advice?

Thanks,
Daisy
