I have two quick questions about using mata:
1) is there a way to get mata to evaluate the content
of a string scalar, e.g.:
if I type:
b="4+5"
then I later type:
b
it returns
4+5
is there a way that I can get it to evaluate b, i.e.
return 9?
2) Is there an easy way to have a function be an
argument for another function? Basically, I'd like to
define a function that allows for different methods
for calculating a value, so I'd like to be able to
specify as an argument for the function which
calculation function to use. I could enter the
calculation function name as a string, and then
concatenate the arguments to the string. Then I get
back to problem 1), how to get mata to execute the
concatenated string.
Thanks for the help. I'm a very rudimentary stata
programmer so I apologize if I'm missing something
obvious.
