[R] meaning of lenwrk value in adapt function

[Eric Archer]

R-listers,

In using the adapt function, I am getting the following warning:

Ifail=2, lenwrk was too small. -- fix adapt() !
 Check the returned relerr! in: adapt(ndim = 2, lower = lower.limit, 
upper = upper.limit, functn = pr.set, 

Would someone explain what the 'lenwrk' value indicates in order to help 
diagnose this issue.
Also, what are the possible codes for Ifail, so I can set some traps in 
my code to handle them correctly.

I apologize for not including a reproducible example in this query, but 
the function that is being called in adapt is a rather complex 
temporal-spatial density function and would require many lines of code 
along with the necessary data, and would not be useful at this stage in 
debugging.

Thanks in advance.

Cheers,
