Hello everyone,
I am trying to add the following text (in proper notation) to a
graphic using expression().
X-bar (with a subscript of cv) = XX.
Note: Ideally "cv" would be a subscript, but it doesn't have to be.
I have the following code:
> text(625,.012,expression(bar(X)cv = 552.01))
Error: unexpected symbol in "text(625,.012,expression(bar(X)cv"
I have also tried the following:
> text(625,.012,paste(as.character(expression(bar(X))),"cv = 552.01",sep=""))
>
While I get no error message for the later, it actually prints
bar(X)
instead of resolving to the proper notation.
Any assistance is appreciated.
Thanks!
Dan
