indeed this makes the trick! quite strange... is this a known bug/issue?
thanks!

Put a space after the # in the line

to avoid the problem. A similar problem also
appears in parse().

Error in `Encoding<-`(`*tmp*`, value = character(0)) :
'value' must be of positive length

expression(log(pi))
attr(,"srcfile")

log(pi)
(I'm still using 2.12.0.)

Subject: Re: [R] error with source(): invalid 'times' value
Do 'str(dep)' to see what dep is and where it comes from. If you have
the 'options' set as I suggested, you can do this examination when the
error occurs.

ok, thanks Jim
The problem comes from length(dep)<leading, so we get
negative number...
length(dep)
[1] 183
c(leading, length(dep) - leading)
[1] 516 -333
But 183 seems to be the right number:
$ wc -l /tmp/RFile.r
183 /tmp/RFile.r
So now need to understand what is this "dep", and why it
has a bigger
length... tried to check source code (:-)) but could not
get it... any idea?
Thanks a lot

It sounds like you have some invalid expressions. Dump
out the values
of 'leading' and 'length(dep) - leading'. Learn some
simple debugging
techniques. One is to set
options(error=utils::recover)
so that on the error you can use the browser to examine
what the values
are.

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
