Readers, I have tried to use a plotmath command to add the temperature degree sign (i.e. ᵒ C) to the axis label of a graph:
> x<-(1:10) > y<-(200:191) > plot(x~y,ylab=expression(*degree~C)) Error: syntax error, unexpected '*', expecting ',' in "plot(x~y,ylab=expression(*" According to plotmath manual, the syntax is '*degree' and I am able to use this command when a number precedes the asterisk (e.g. ylab=expression(0*degree~C)). But I want to omit the need for a number before the degree sign. Any advice please? ______________________________________________ R-help@r-project.org mailing list 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.
