[R] Error: cannot change value of locked binding for

[Martin Becker]

Did you have a look at the posting guide?
We have to guess that you are using some version of fOptions in some 
version of R under some OS, and that you run code from the examples 
section of ?MonteCarloOption relying on other code from that section 
which is not mentioned at all. Given that these guesses are correct:
The first parameter of MonteCarloOption should read "delta.t", not "dt" 
(at least in fOptions version 241.68). If you are using "dt" because you 
have an old version of fOptions and "dt" is correct for that version, 
try updating fOptions, otherwise maybe changing "dt" to "delta.t" helps.
