After further investigation it appears that the problem is specific to
my Vista PC. I am able to get the correct results using R 2.9.2 on a
Window XP 64bit machine. However i do not know why this does not work
on my Vista PC. The following was done after rebooting Vista.
From CMD.exe I ran the
UPDATE:
I'm not sure why, but on my Windows XP 64bit machine, I ran the same
code again and this time it is not working even though it worked
previously. This has been done using the Rgui --vanilla command.

SOLVED.
Thanks to a reply off-list it appears that the 'space' in published

Dear all,
I'm having a problem understanding why a split does not occur with in
the 2nd use of the function strsplit below:
# text strings

+ sales to 6 September 2008 published 11 September)
# first use
strsplit(txt, 'published',

txt - c(sales to 23 August 2008 published 29 August,sales to 6
September 2008 published 11 September)
strsplit(txt, 'published ', fixed=TRUE)

[1] sales to 23 August 2008 29 August
[[2]]
[1] sales to 6 September 2008 11 September

I am using the exact same version of R as you also on Vista
but can't reproduce your result. For me it splits properly.
Try starting R like this (modify path if needed) from the
Windows cmd line:
\Program Files\R\R-2.9.2\bin\Rgui --vanilla
and then try it.
