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

[Matthieu Stigler]

hi

I am seeing a strange behavior I can't understand... doing:

 > source("/tmp/RFile.r",echo=TRUE)
Error in rep.int(c(prompt.echo, continue.echo), c(leading, length(dep) -  :
   invalid 'times' value
 > traceback()
3: rep.int(c(prompt.echo, continue.echo), c(leading, length(dep) -
        leading))
2: paste(rep.int(c(prompt.echo, continue.echo), c(leading, length(dep) -
        leading)), dep, sep = "", collapse = "\n")
1: source("/tmp/RFile.r", echo = TRUE)
 >

But the file I am trying to source is very simple... see:
$ more /tmp/RFile.r
###################################################
### chunk number 1:
###################################################
#line 516 "VolStocksDec2010.Rnw"
path<-"~/Dropbox/FAO/Papers/Volatility only"
pathMarkov<-"~/Dropbox/FAO/Markov Model/"
library(zoo)

Any idea where it can come from? It works fine when echo=FALSE... I am 
using R 2.12, on Ubuntu Linux 10.4 (R from CRAN), full session info 
below. Should I rather send this to r-devel?

Thanks a  lot

Matthieu
