Error: file.exists(filename) is not TRUE

[Steve Cumming]

It would be convenient if some clue were provided as to which file does not exist. This, when running simInit()

Can you please try to put a reproducible example?

Eliot asks that I submit a reproducible example, but

a) there are innumerable conditions that could trigger this error

b) I thought the matter was fairly straightforward

In this instance, many different kinds of booboos in filepath specifications cause simInit to fail, with the indicated error message:

Error: file.exists(filename) is not TRUE

It would help with the finding of the problem if "filename" were printed. Yes, one can eventually track it down, but especially for those of us just learning, it would make things go faster if we knew which "filename" was problematic.

[Eliot McIntire]

There is now an informative error, and it reports filename and also how that filename was generated (i.e., by concatenating modulePath with module name). It is now in the development branch: install_github("PredictiveEcology/SpaDES", ref="development")

Thanks very much for this, Eliot. I am sure it really will help a lot of people out, not just me.
