Hello.
I have a question that probably has a simple answer.
I have a loop where several figures are plotted with each iteration. I
calculate some descriptives to put in the title of the figure. When I use
expression, since I want to combine math plotting symbols and the descriptives
I calculate, I get an error. Here is an example of the code that I tried:
plot(x,y, main=expression(paste("ID is", ID.i, italic(R)^2, r2.i, "RMSE",
error.i)))
where ID.i, r2.i, and error.i change for each iteration of the loop. I suppose
the problem is that expression does not know to treat each of these as objects
rather than part of a mathematical expression. Is there a way to display the
value of ID.i, r2.i, and error.i within the expression?
Thanks for any thoughts,
Ken
