[R] error with source(): invalid 'times' value

[Duncan Murdoch]

This is somewhat fixed now in R-patched and R-devel, as of revision 
54235.  It won't die with an error, but it still might not be perfect.

The problem is that the line

#line 516 "VolStocksDec2010.Rnw"

is taken as a statement by you that the next few lines are copied from 
line 516 and following in the "VolStocksDec2010.Rnw" file.  If that's 
not true (e.g. that file doesn't exist any more, or has changed) you 
might not get what you want in the echoed code.

I may still make some more changes:  either stop Stangle from including 
those lines, or add an option to source() to get it to ignore them.  The 
trouble is that those lines are often useful:  they're how errors are 
reported relative to the original Rnw file, rather than the intermediate 
tangled file.  I've added a note to ?source to point out that there 
might be a problem; I may just stop with that.
