R and SAS
Hi
I'm trying to read SAS-data on VAX/VMS to Windows R using
foreign pakage read.xport and experience some problems.
Following lines are used in SAS to create XPORT file
LIBNAME a ''xxx;
LIBNAME b XPORT '';
PROC COPY IN=a OUT=b;
RUN;
and I succeed in getting file that looks like correct xport

Prediction interval of Y using BMA
Hello everybody,
In order to predict income for different time points, I fitted a linear
model with polynomial effects using BMA (bicreg(...)). It works fine, the
results are consistent with what we are looking for.
Now, we would like to predict income for a future time point t_next and of
course draw the prediction interval around the estimated value for this
point t_next. I've found the

how to use the EV AND condEV from BMA's results?
Dear friends,
In R, the help of "bic.glm" tells the difference between postmean(the
posterior mean of each coefficient from model averaging) and
condpostmean(the posterior mean of each coefficient conditional on the
variable being included in the model), But it's still unclear about the
results explanations, and the artile of Rnews in 2005 on BMA still don't
give more detail on

unlockEnvironment()?
R lets one lock an environment with both an R function,
base::lockEnvironment, and a C function, R_LockEnvironment, but, as far as
I can tell, no corresponding function to unlock an environment. Is this
omission on principle or just something that has not been done yet?
I ask because several packages, including the well-used R6 and rlang
packages, fiddle with some bits in with SET_ENVFLAGS and

annoying authentication failure problem: sambatest[ho stname]
Hi Toni,
This error is the result of a test that samba does in the module
"server_validate", (in password.c) to check the password server for a bug
where NT 4 (some versions) would not correctly set the guest bit.
There is currently no smb.conf parameter to allow you to control this
behavior, so to change it , you would need to actually hack the password.c
module to disable it.

levelplot/heatmap question
Hello!
I have data containing a large number of probabilities (about 60) of nonzero
coefficients to predict 10 different independent variables (in 10 different
BMA models). i've arranged these probabilities in a matrix like so:
(IV1) (IV2) (IV3) ...
p(b0) p(b0) p(b0)
p(b1) p(b1) p(b1)
p(b2) p(b2) p(b2)

where p(b1) for independent variable 1 is p(b1 !=

Kernel lockup (kjournald?)
I am getting an odd situation when backing up a number of ext3 filesystems
and was wondering if it could be caused by journalling. Over the space of
a minute the load average will jump from 2 to over 40 and the system will
be unresponsive for anywhere from 8 to 25 minutes. I am going to be trying
a number of things, but was wondering if anyone could see the reason for

step factor below minimum
I am trying to fit the 4-parameter logistic model with SSfpl. The
estimation is terminated with a message "step factor 0.000488281 reduced
below 'minFactor' of 0.000976562". I tried to change the minFactor with
nls.control(minFactor=yy) with no apparent success. A call of
nls.control() without arguments always shows the value of 0.000976562.

I have a little problem which appeared when I installed first 2.2

R-News 5/2, Bayesian Model Averaging, a detail
The article on BMA (Bayesian model averaging) presents most valuable tools for model selection, but I find one detail confusing in Example 1. In page 4 of RNews 5/2, second paragraph says that the probability of Time variable not being in the model is 0.445. It seems to me that the figure should be 1 - 0.445 = 0.555, because p!=0.445 is the prob. of Time variable being in the model. The plot in

Seeking optimal mixture
This is maybe not directly an R problem but I have used R to try to solve
it so I think somebody may be able to help.
I have a mixture model with three components and a quadratic Scheffe
polynomial p1x1+p2x2+p3x3+p12x1x2+p13x1x3+p23x2x3 fitted to the response.
Now I'd like to compute the mixture corresponding the maximum response.
Model for Y1 has the parameters
p1=124.02
p2=60.973
p3=41.479

Leaps and bound
Hi,
I used the bic.surv function, S-PLUS functions developed by Chris Volinsky
http://www.research.att.com/~volinsky/bma.html, without problems with
S-PLUS.
I have to use it with R but I am face with a problem: this function call a
fortran routine named "leaps" (answer <- .Fortran("leaps", arguments)). I
loaded the leaps library, and the leaps function work well with my R,
