Hi All R-Gurus,
I am trying to debug a program, and I think tryCatch will help. The functions
involved
process through so many times before I encounter the error, things are a bit
slow to
use debug and browser().
I've read the help file and postings on conditions, and am still having trouble.
While running my program I am getting a NAN from a called function, and I want
to know the
input parameters that generate this, so I have included the following in the
code of the main
function (calling function):
tryCatch(delM > S, exception=function(e)print(list(S=S, Si=Si, D=D, theta=S/N,
incr=del.t)), finally=print("finally"))
This is actually part of an "if" statement, where delM > S is the condition.
Now if delM is an NAN an error results.
Now the above tryCatch does not work in the way I wish it. What sort of
condition does this little expression throw when it encounters delM=NAN? is it
an exception? What is wrong with the above handler etc?
Kind regards,
Matt Redding
