No "number of days" format for 'difftime'?
Thanks for the link, John. However, there is a hyphen missing. It should be: http://www.dummies.com/how-to/content/how-to-read-errors-and-warnings-in-r.html Appropriately, with the correct URL we find the too often forgotten pearl of wisdom: "Chances are, you just typed something wrong there." I think I need this on my coffee cup. Cheers, Loris John Kane <jrkrideau at inbox.com> writes:

If something goes wrong with your code, R tells you. We have to admit
it: These error messages can range from mildly confusing to completely
incomprehensible if you?re not used to them.
fortune(350) regarding the on-line help is also inspiring
You need to get the hang of reading the online help. The information
required is actually therein ?dotchart --- it's just tersely and
obscurely expressed. A certain degree of optimism is required. You
need to ***believe*** that the information is there; then ask yourself
"What could they possibly mean by what they have written that would
tell me what I need to know?".

Hi, I was probably misled by the, to my mind, esoteric error message into thinking the error was more subtle. Something like "unmatched quotes" might have helped me recognise that I was just being dopey. Thanks to John and Rui. Loris <ruipbarradas at sapo.pt> writes:
Hello, You're missing a double quotes. Right after format= Hope this helps, Rui Barradas Citando Loris Bennett <loris.bennett at fu-berlin.de>:
Hi,
When I try
d <- as.difftime("6-08:18:33",format=%d-%H:%M:%S")
I get:
Error: unexpected SPECIAL in "as.difftime("6-08:18:33",format=%d-%"
Am I correct in thinking that it is not possible to do something like
this, because there is no character string for the format which
corresponds to "number of days"?
I could misuse "%j" for "day of the year as a decimal number", but
ultimately the "difftime" object is still a data, rather than a length
of time and I should be looking at a package like 'lubridate' instead.
Is that the case?
Cheers,
Loris
