error with source(): invalid 'times' value

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

Thanks for your quick answer!
Unfortunately, it does not change:
source("/tmp/RFile.r", echo = TRUE, prompt.echo = NULL, continue.echo =
"+ ")
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, prompt.echo = NULL, continue.echo
= "+ ")

note this is not a systematic problem, but can't say exactly when/why it
works or not...

thanks

Re: error with source(): invalid 'times' value

In reply to this post by Matthieu Stigler

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.

Re: error with source(): invalid 'times' value

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

Matthieu

Check getOption("prompt.echo") and getOption("continue") and try
different values for the prompt.echo= and continue.echo= arguments of
source. I am able to get your times error by using source("myfile.R",
echo = TRUE, continue.echo = NULL)

Re: error with source(): invalid 'times' value

In reply to this post by Matthieu Stigler

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.

Re: error with source(): invalid 'times' value

Put a space after the # in the line
#line 516
to avoid the problem. A similar problem also
appears in parse().

> parse(text="#line 102\nlog(pi)\n")
Error in `Encoding<-`(`*tmp*`, value = character(0)) :
'value' must be of positive length
> parse(text="# line 102\nlog(pi)\n")
expression(log(pi))
attr(,"srcfile")
<text>
attr(,"wholeSrcref")
# line 102
log(pi)

(I'm still using 2.12.0.)

Re: error with source(): invalid 'times' value

In reply to this post by jholtman

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!!

Indeed 2.12.1, sorry for imprecision! I will give a try to
2.12.1-patched, although I am not so sure how I can install it (should I
compile) on linux...

It is known now. The problem arises while
printing the output of parse because the srcref
attribute contains the numbers from those
#line <number>
entries and the printing routine gets confused
if the numbers are out of the range 1 through
the number of lines of text.

Bill Dunlap has already confirmed that this is not what was fixed (or
what was fixed never made it into the sources). I'll get to it, but not
for a couple of weeks.

Re: error with source(): invalid 'times' value

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.
