I'd like to annotate a lattice plot, e.g. xyplot, with text containing both
Greek letters and variable values. In the base graphics plot command this
can be accomplished with e.g. main =
substitute(paste(lambda,"=",var),list(var=var)), where var is a variable
that contains the value. When I try to do this in xyplot, I get the error
message "object 'lambda' not found". Any ideas on how to do this in xyplot?
Thanks for the help!
