ks.test one-sample - where can I get a list of the strings specifying the distribution?
Dear all,
One can use ks.test(x,y) for a one-sample kolmogorov-smirnov test:
x being the data sample
y being a string specifying a distribution
I notice the help on ks.test does not tell you how to get such a list. Is
this a hole in my R knowledge?
Where can I get a list of the strings specifying the possible
distributions?
and more specifically
What would be the string and following

RODBC, sqlSave and sqlAppend
Hi all,
I am currently trying to read, write and append data between R and MS access
using the RODBC library functions. I have no problems reading in the data
but when using sqlSave and sqlAppend it doesn't seem to work. I have made
sure that all the column names are sensible and there are no gaps etc in the
variables. My call looks like this:

test for whether dataset comes from a known MVN
Dear all,
I have a multivariate dataset containing 100,000 or more points.
I want find the p-value for the dataset of points coming from a
particular multivariate normal distribution
With
mean vector u
Covariance matrix s2
So
H0: points ~ MVN( u, s2)
H1: points not ~ MVN( u, s2)
How do I find the p-value in R?
To me this is a likelihood ratio test problem.
In H0 the parameters are

Boost library in R package.
Hi R package developers,
I would like to know whether anyone had experience using the C++ Boost
library within an R package, and how portable was the resulting package.
I am especially thinking of possible compiling problems on Windows and
Apple systems.
If anyone had any tips on how to render an R package using Boost
portable, that would be very much appreciated.
Thank you very much for

Can you subset with the context of RExcel
Hi all,
I am trying to use RExcel at the moment. I am able to get it to work for
simple commands, but I can't seem to get it to work when I subset the data.
So for example, if I start RExcel, and then 'Put R var' with the following:
1 1 2
2 1 2
3 1 2
4 1 2
5 1 2
6 1 2
7 1 2
8 1 2
9 1 2
10 1 2
and set it to variable x, then I 'run R' on the code 'z <- t(x)' and

dovecot-lda can't create /var/mail dotlocks on debian
I've been using dovecot+postfix happily for many years, and I'm now
configuring it for a new machine. However, I'm running into an old problem
again, and thinking that there must be a better solution.
The problem is that dovecot-lda is unable to create dotlock files in the
/var/mail directory.
Dovecot version: 1:2.2.13-12~deb8u1 (I'm guessing this is upstream version
2.2.13)

Tetrachoric and polychoric ceofficients (for sem) - any tips?
About two years ago there was a thread about this which suggested that at
that time nobody had these coefficients ready to go.
(a) has anyone in the meanwhile programmed them?
(b) I think I can see how to do the tetrachoric one with mvtnorm on similar
lines to an example on the help page so will try that if nobody else
already has
(c) looking at the polychoric one makes me realise yet again

Assignment from list
I have a list of groups of xy positions I want to set to 0 in an
array full of 1s. When the assignments are done directly from the
list, they are incorrect, while if I use a temporary array derived
from the list the assignments are correct. The following example will
hopefully make my problem clearer.
The matrices z and zz are initialised with 1. The z and zz values at
coordinates in

Fisher's exact test vs Chi-square
Timothy,
I believe you are mistaken. Fisher's exact test give the correct answer
even in the face of small expected values for the cell counts. Pearson's
Chi-square approximates Fisher's exact test and can give the wrong
answer when expected cell counts are low. Chi-square was developed
because it is computationally "simple". Fisher's exact test,
particularly with tables

logistic regression in an incomplete dataset
Dear all,
I want to do a logistic regression.
So far I've only found out how, in a dataset of complete cases.
I'd like to do logistic regression via max likelihood, using all the study
cases (complete and incomplete). Can you help?
I'm using glm() with family=binomial(logit).
If any covariate in a study case is missing then the study case is
dropped, i.e. it is doing a complete case
