sequential t-test - replies
[my original message to s-news & r-help is attached ]
No one possessed or knew of any S/R code for the sequential t-test. Also
it doesn't appear in the SAS index.
One or two suggested obtaining the S+ seqtrial software which may (or may
not) cover this, but this seemed to be a bit of a "hammer to crack a nut".
I have written a function based on the treatment in Wetheril

running R from Notepad++ in Windows 7
hi Andrew
Many thanks for the suggestion.
I gave it a try , but still get the same issue -
a fresh Rgui window (just one) opens, with an empty .RData, when
I submit a script ( Ctrl & F8 ).
I also tried running things as administrator, but it made no difference.
Apparently windows 7 is selling like hot buns, so there should be
enough market pressure before too long , to encourage the

responses to my question on non-central t
The original question is attached at the end of this message ...
In the world of R the excellent mvtnorm package answers my original
question and many more that I didn't know I needed to ask.
In the world of Splus ( version 6 , Windows XP ) this link :-

which was provided by Dimitris Rizopoulos, is useful.

Also - does anyone know is there an Rstudio-user email-list forum thingy

non-central t : R v.Splus
Hi
For bureaucratic reasons beyond my control I need to rewrite an R function
(for producing operating characteristic curves) as an Splus function (
version 6 , windows XP ).
The R function makes extensive use of the fact that the student's t
distribution function pt() has a non-centrality parameter built in ...
sadly that parameter is not present in the Splus pt() function .

Is there an R implementation for the "Barnard's exact test" (a substitute for fisher.test) ?
Hello R help members. I came across today with an article on Barnard's exact
test (http://www.cytel.com/Papers/twobinomials.pdf), that is supposed to
give a more powerful fisher.test - Because it doesn't assume that we know
the row and column totals are in advance. Any pointers to such a function ?
Thanks, Tal

moving from Windows to Linux - need help
hi
I've used R for many years on windows machines, but
have now acquired an Asus eee 1000 linux machine.
In order to get the best out of the machine, I used the
'pimpmyeee.sh' script, to get the full KDE desktop.
The version of Linux is Xandros, which I believe is
a close relative of Debian, but sadly I have only a
nodding acquaintance with Linux at present.
Naturally I want to

time-ordered object list
It's often useful to view objects in time order.
In Splus I can do this with

which delivers this sort of thing ...

Samba 3.0.28a integration with 2003 AD and password lockout policy?
I'm encountering some oddness using Samba 3.0.28a, MIT kerberos (1.6.3)
for user authentication on Linux, to 2003 Active Directory.
The password policy dictated by AD should lock accounts after 6
incorrect login attempts within a 30 minute period. However, it seems to
halve that when logging in to these Linux boxes via ssh - so after 3
incorrect login attempts, the AD account gets locked.

Bug in Kendall for n<4?
> library(Kendall)
> Kendall(1:3,1:3)
WARNING: Error exit, tauk2. IFAULT = 12 <<<<<<
tau = 1, 2-sided pvalue =1
I believe Kendall tau is well-defined for this case and the reported
value is correct; isn't it a bug to give a warning? (And if, e.g.,
the pvalue is not well-defined in this case, wouldn't it be better to
return NA or NaN or something?) Also,
