Multiple imputation, multinomial response & random effects
Dear R-group,
Could somebody recommend a package that can deal with a multinomial response variable (choice of breeding tactic in mice, which has four unordered levels), multiply-imputed data (generated using the Amelia package) and two non-nested random effects: individual identity (133 individuals made up to four choices each) and year (for which there are six levels and sample size varies

Question about 'logit' and 'mlogit' in Zelig
I'm running a multinomial logit in R using the Zelig packages. According to str(trade962a), my dependent variable is a factor with three levels. When I run the multinomial logit I get an error message. However, when I run 'model=logit' it works fine. any ideas on whats wrong?

Multinomial Logit Model with lots of Dummy Variables
Hi All,
I am attempting to build a Multinomial Logit model with dummy variables of
the following form:
Dependent Variable : 0-8 Discrete Choices
Dummy Variable 1: 965 dummy varsghpow at student.monash.edu.augh@gp1.com
Dummy Variable 2: 805 dummy vars
The data set I am using has the dummy columns pre-created, so it's a table
of 72,381 rows and 1770 columns.
The first 965 columns represent

logit model interpretation
Hello everyone
I appologize for my lack of experience in statistical methods. I am an R
user begginer and I am running a logit model using "zelig" and "pcse"
packages. I will go to the point and is that Im having problems with
interpreting the results of my models.. It is really simple (I guess for the
most advanced scholars) however I really dont understand how to interpret

Request: Increasing MAX_NUM_DLLS in Rdynload.c
This is a request to increase MAX_NUM_DLLS in Rdynload.c in from 100 to 500.

In development of the mlr package, there have been several episodes in the
past where we have had to break up unit tests because of the "maximum

Request: Increasing MAX_NUM_DLLS in Rdynload.c
Thanks Henrik this is very helpful! I will try this out on our tests and
see if gcDLLs() has a positive effect.
mlr currently has tests broken down by learner type such as classification,
regression, forecasting, clustering, etc.. There are 83 classifiers alone
so even when loading and unloading across learner types we can still hit
the MAX_NUM_DLLS error, meaning we'll have to break them

multi-regression with more than 50 independent variables
Hi R Users,
I am going to run a multiple linear regression with around 57 independent
variables. Each time I run the model with just 11 variables, the results
are reasonable. With increasing the number of independent variables more
than 11, the coefficients will get ?NA? in the output. Is there any
limitation for the number of independent variables in multiple linear
regressions in R? I attached

That dreaded floating point trap
Hi,
I had a piece of code which looped over a decimal vector like this:
for( i in where ){
thisdata <- subset(herde, herde$mlr >= i)
# do stuff with thisdata..
}
'where' is a vector like seq(-1, 1, by=0.1)
My problem was: 'nrow(thisdata)' in loop repetition 0.4 was different if
'where' was seq(-1, 1, by=0.1) than when 'where' was seq(-0.8, 1,

140 packages in R Commander!!
Dear List
I just downloaded and installed R 2.12.0 and then installed R Commander .
First it got RCmdr and Car, and then suggested for other packages for
utilizing the full functionality- I clicked yes!
I got 140 packages installed!!! Cran Mirror was UCLA...
Here is the list.
Is this intentional- I can see some packages like snow and multicore which
are desirable but quite optional.(see list

argh .. if/else .. why?
Hello, would someone please help explain the following inconsistency
in the if/else statement to me?
The format of the if/else #3 below is ok, but if/else #1 is not? (I get
an "unexpected else" type error.) In order for it to work I have to use
if/else #2
Thanks .. maybe there is some reason for this, but this looks very
inconsistent to me.

Mixed multinomial logit model (mlogit script)
Dear all,
I am trying to run a mixed multinomial logit model in R since my response variable has 4 non-ordinal categories. I am using the package mlogit that estimates the parameters by maximum likelihood methods. First of all, I prepared my data using the mlogit.data command. In the mlogit command, one can introduce alternative-specific (fixed factors??) and individual-specific (random
