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

[mat]

Hi

Well this is the output of str(dep) on a small example:
str(dep)
  chr [1:8] "###################################################" ...
Browse[1]> dep
[1] "###################################################"
[2] "### chunk number 1:"
[3] "###################################################"
[4] "#line 516 \"VolStocksDec2010.Rnw\""
[5] "path<-\"~/Dropbox/FAO/Papers/Volatility only\""
[6] "pathMarkov<-\"~/Dropbox/FAO/Markov Model/\""
[7] "library(zoo)"
[8] ""

it seems quite accurate... I guess the problem comes form leading... 
even if this smaller example, it is still the same number (516) as in 
the test with bigger source doc...

Can you reproduce this on your machine? I can reproduce it on two Linux 
buntu 10.4, R 2.12.1 ...

Thanks!!
