[R] mysterious warning message regarding bytecode...

[Justin Haynes]

While running a long script which source()s other scripts I get the
following warning:

Warning message:
In t(object$S[[1]]) : bytecode version mismatch; using eval


I cannot replicate it if I run the sourced files line by line though...

What is that error?  And do I care about it?  It doesn't seem to
affect my output as far as I can tell.


Thanks!
Justin
