If this was a base graphic plot, I'd use mtext, but I'm not sure how

Here is some example data:

The changes makes the script fail, saying somtehing like: abscent value
where TRUE/FALSE is necessary, the variables that are supposed to pass the
information to the Valuation.R script are empty, and error comes because it
does something like this at some point:
VarX = A/B #But because the variables values are not getting into the
Valuation.R script then
#A = MCPVMPA = 0 and B = MCMKMPA = 0
So VarX = NaN
Then it does something like:

(Page 14 - DSE Package Manual)
I obtain a Segment Violation.

To add to the other response, it is important to note that your %var1,
%var2 above are not variables at all, because they can't be reassigned
(i.e. they can't appear again on the left hand of a %varX = ...
expression.) They are just names for the values corresponding to the
instructions.

Solving two nonlinear equations with two knowns
Dear R users,
I have two nonlinear equations, f1(x1,x2)=0 and f2(x1,x2)=0. I try to use optim command by minimize f1^2+f2^2 to find x1 and x2. I found the optimal solution changes when I change initial values. How to solve this?
BTW, I also try to use grid searching. But I have no information on ranges of x1 and x2, respectively.
Any suggestion to solve this question?
Thanks,
Kate
