Integration of functions with a vector argument
Hello all,
I have a question concerning integration of a function of a multivariate argument with respect to one or more variables in r. Let us say we have a function
F <- function(x){ body of the function}
Where x is, in general, a d by 1 vector with d>1. Now I want to integrate out some of the coordinates of x, e.g. x[1] or x[2] or both of them etc. I'm well aware of how to

Logistic regression - confidence intervals
Please forgive a rather na??ve question...
Could someone please give a quick explanation for the differences in conf intervals achieved via confint.glm (based on profile liklihoods) and the intervals achieved using the Design library.
For example, the intervals in the following two outputs are different.
library(Design)
x = rnorm(100)
y = gl(2,50)
d = data.frame(x = x, y = y)
dd = datadist(d);

Likelihood ratio based confidence intervals for logistic regression
I'm applying logistic regression to a moderate sized data set for which I
believe Wald based confidence intervals on B coefficients are too
conservative. Some of the literature recommends using confidence intervals
based on the likelihood ratio in such cases, but I'm having difficulty
locating a package that can do these. Any help would be immensely
appreciated.
Best,
Jeff Hanna

Integration of functions with a vector argument

> f.int1 <- function(x,y) {Vectorize (function(y) f(c(x,y),H=H,j=j))}
Vectorize returns a callable function(y), so wrapping it in a
function(x,y) will not work. Since you'd like to integrate over y, we
can perform the same transformation manually using vapply:

Incomplete Output from lmer{lme4}
I'm still relatively new to R, so my apologies if this is covered
somewhere. I've been running some mixed-effect models in R using
lme{nlme}, but read in Faraway's recent book, Extending the Linear Model
with R, that lmer in package lme4 is a much improved version. I tried
using this approach, but the output for the fixed effects doesn't report
a p-value or the degrees of freedom

multivariate regression using R
Does anyone know if there is a way to run multivariate linear regression
in R? I tried using the lm function (e.g., lm(dv1, dv2~iv1+iv2+iv3),
but got error messages. Is my syntax wrong, or do I need a particular
package?
Thanks,
Jeff--

Regarding your distributed text mining with tm
Hello,
I had been using R for text mining already. I wanted to use R for large
scale text processing and for experiments with topic modeling. I started
reading tutorials and working on some of those. I will now put down my
understanding of each of the tools:
1) R text mining toolbox: Meant for local (client side) text processing and
it uses the XML library
2) Hive: Hadoop interative, provides the

NT_STATUS_LOGON_FAILURE
I recently upgraded from RedHat 6.2 to 7.3. I had samba running
fine so I could mount space on our windows network. Somehow this
got broken in the upgrade. My linux box is called k466a and my
username there is mcliff. On the windows network I am cliffm.

log format question: resolved
It was pointed out that this information is in the --itemize-changes parameter in the man page.
I looked at the man page but missed this part. I guess it was the forest for the trees.
Thanks and it is resolved.

how to easily access S-PLUS data sets in R?
Dear R-help colleagues,
Greetings! I'm interested in using some of the data sets from S-PLUS in
a class that I'm teaching on R. Our university has a license for
S-PLUS, and I recognize that data sets from S-PLUS can be individually
exported from S-PLUS and then imported into R.
Is there a more straightforward way to do this? For instance, are the
data sets from S-PLUS freely

ZIB models
I attempted to contact Drew Tyre, but the email I have for him is no
longer in service.
Hopefully someone can help.

I've been testing in smaller groups.

Problems with -with-sandbox=solaris on Solaris 10
I was involved with the issues building OpenSSH 7.2p1 to use the
Solaris sandbox, but I ended up dropping out of the discussion
due to being on the road for most of the last couple of weeks.
Anyway, the problems persist with OpenSSH 7.2p2 when building
with --with-sandbox=solaris. I found that there's an error in
openbsd-compat/port-solaris.h on line 30, because the type
