aregImpute: warning message re: acepack and mace
hi,
i'm trying to learn how to use aregImpute by doing the examples provided with
the package, and after installing Hmisc.1.6-1.zip (for Windows),
and running the very first example on R 1.7.1, i get an error message warning
me about "mace" (see below) and acepack.
i found the acepack package, but its filename ends in tar.gz

Difficulty replacing NAs using Hmisc aregImpute and Impute
Hello R experts
I am using Hmisc aregImpute and Impute (following example on page 105 of The
Hmisc and Design Libraries).
*My end goal is to have NAs physically replaced in my dataframe. I have
read the help pages and example in above sited pdf file, but to no avail.
Here is example of what I did.

aregImpute (Hmisc package) : error in matxv(X, xcof)...
Dear r-help list,
I'm trying to use multiple imputation for my MSc thesis.
Having good exemples using the Hmisc package, I tried the aregImpute function. But with my own dataset, I have the following error :
Erreur dans matxv(X, xcof) : columns in a (51) must be <= length of b (50)
De plus : Warning message:

Hmisc's aregImpute segfaults R-1.7.0 under linux
Hello -
When trying to use Hmisc library's aregImpute function on R 1.7.0, I

as.character and a formula
Dear list,
given this formula:
> fmla <- formula(y1 ~ spp1 + spp2 + spp3 + spp5)
> fmla[[3]]
spp1 + spp2 + spp3 + spp5
is this the intended behaviour of as.character:
> as.character(fmla[[3]])
[1] "+" "spp1 + spp2 + spp3" "spp5"
? Where does the extra "+" come from?

update.formula has 512 char buffer?
Hello,
I am trying to "paste" together a formula to use in the mob function of

I am doing some preliminary fits of y ~ x1+ ...+xM, then want to add the
conditional part of the equation using update().

ARM vectorized fp16 support
Hi,
I'm trying to compile half precision program for ARM, while it seems
LLVM fails to automatically generate fused-multiply-add instructions
for c += a * b. I'm wondering whether I did something wrong, if not,
is it a missing feature that will be supported later? (I know there're
fp16 FMLA intrinsics though)

Re: extracting datasets from aregImpute objects
I've tried doing this by specifying x=TRUE, which provides me with a single imputation, that has been useful. However, the help file possibly suggests that I should get a flat-file matrix of n.impute imputations, presumably with indexing. I'm a bit stuck using alternatives to aregImpute, as neither MICE nor Amelia seem to like my dataset, and Frank Harrell no longer recommends Transcan

using a string as the formula in rlm
Hi,
I am trying to build a series of rlm models. I have my data frame and
the models will be built using various coulmns of the data frame.
Thus a series of models would be
m1 <- rlm(V1 ~ V2 + V3 + V4, data)
m2 <- rlm(V1 ~ V2 + V5 + V7, data)
m3 <- rlm(V1 ~ V2 + V8 + V9, data)
I would like to automate this. Is it possible to use a string in place
of the formula?

Design functions after Multiple Imputation
I am a new user of R for Windows, enthusiast about the many functions
of the Design and Hmisc libraries.
I combined the results of a Cox regression model after multiple imputation
(of missing values in some covariates).
Now I got my vector of coefficients (and of standard errors).
My question is: How could I use directly that vector to run programs such
as 'nomogram', 'calibrate',

PDC samba
Hi,
Got two questions.
1. If I'd added a machine to my domain (using samba as pdc) with the
followig commands:
/usr/sbin/useradd -g machines -c XPMachine -d /dev/null -s /bin/false $1$
/usr/bin/smbpasswd -a -m $1$
How should I then remove one of them if made a mistake osv?
2. How can I change the adminpassword for PDC?

nls() fails on a simple exponential fit, when lm() gets it right?
Dear R-help,
Here's a simple example of nonlinear curve fitting where nls seems to get
the answer wrong on a very simple exponential fit (my R version 2.7.2).
Look at this code below for a very basic curve fit using nls to fit to (a)
a logarithmic and (b) an exponential curve. I did the fits using
self-start functions and I compared the results with a more simple fit
using a straight lm()
