[R-sig-Geo] Is there a function for comparing a modeled timeseries to the measured one?

[Aman Verma]

Hi Jan,

In general, R-squared can be calculated as the square of the correlation coefficient.

However, read here to understand what R-squared means in this case:

Dear R - Users
I have 2 timeseries, one measured and one is modeled. The only function to
compare them  i know is cor(model,measured). Is there perhaps another
function to produce the r squared, to prove that my model is well fit?
Thanks for your time
Jan
