Rounding in print.summaryDefault()
Might this be related to the Linux version? I'm testing on one of our
university servers, and they tend to be deprived of regular updates
sometimes... (Dirk, sorry for sending you this twice.)

I'm using maxlik with functions specified (L, his gradient & hessian).
Now I would like determine some robust standard errors of my estimators.
So I 'm try to use vcovHC, or hccm or robcov for example
but in use one of them with my result of maxlik, I've a the following

Package Matrix
Hi Dirk!
It would be great if you could upload a (Debian) package "r-cran-matrix"
that includes the latest version of the R package "Matrix" to
http://cran.r-project.org/bin/linux/ubuntu/intrepid/
"r-recommended" depends on "r-cran-matrix", but only the (outdated) version
that shipped with intrepid (0.999375-10-1) is currently available.

make apply() return a list
Hi,
I have a dataframe (say myData) and want to get a list (say myList) that
contains a matrix for each row of the dataframe myData. These matrices are
calculated based on the corresponding row of myData. Using a for()-loop to do
this is very slow. Thus, I tried to use apply(). However, afaik apply() does
only return a list if the matrices have different dimensions, while my
matrices have

How to return individual equation from {aidsEst} in package [micEcon]?
Hi, R core team
I am using the function {aidsEst} in package [micEcon] to do an AIDS
model now. So far, everything is good. But I want to test the auto
correlation and heteroskedasticity of the individual equation from AIDS
demand system. How can I return the individual equation?
PS: serial correlation test is {bgtest} in package [lmtest] and
heteroskedasticity is {bptest} in package

constraints
Is there a package in R that handles general linear (in-)equality + box
constrained optimization?
If it is not there, could anyone advise me which way to go?
And/or point me to packages that solve these problems partially?
best, ingmar

HTML help solveLP(linprog) (PR#11250)
Dear R team!
=20
I found in HTML help for function solveLP(linprog) a small mistake. It
says in Description "Minimizes c'x, subject to A x >=3D b and x >=3D 0", but
tests show that there should be A x <=3D b.

R for economists (was: Almost Ideal Demand System)
Hi,
I did not find any web page about using R in economics and econometrics so
far. However, this does not mean that there is none (searching with google
for "R" and "economics" gives many pages about economics and a name like
Firstname R. Lastname on it ;-)).
Does anybody in the list does know such a web page?
If not, I will be happy if you, Ajay, could build and

systemfit - SUR
Hello to everyone,
I have 2 problems and would be very pleased if anyone can help me:
1) When I use the package "systemfit" for SUR regressions, I get two
different variance-covariance matrices when I firstly do the SUR
regression ("The covariance matrix of the residuals used for
estimation") and secondly do the OLS regressions. In the manual for

Creating an S3 method when the generic function is defined in another (imported) package
Hi,
In one of my packages (maxLik), I would like to add an S3 method,
where the generic function (estfun) is defined in another package
(sandwich). Everything works fine if my package "Depends" on the other
package and I import the generic function "estfun" from the "sandwich"
package and define the new method in the NAMESPACE file. However, I

I noticed that there is a (minor) bug either the command all.equal()

Tobit Fixed Effects
Hi there,
I need to run a Tobit Fixed Effects in a panel data with 4500 units for 8
years. It is a huge data set, my dependent variable is left truncated at
zero, the distribution is skewed and my panel is balanced.
Any suggestions on how to do that in R?
I tried stuff like survreg, censReg, and tobit but none of them were
satisfactory.
Thanks,

R CMD check warning on predict.systemfit
Hi,
I added a new function "predict.systemfit" to our package "systemfit" to make
it closer to other packages (e.g. lm). Now "R CMD check" complains that the
generic function "predict" has only the argument "object", while our function
"predict.systemfit" has more arguments. However, the function "predict.lm"
has also more

I have searched google and read sever R-help articles with this error.

Splitting up the micEcon package?
Dear R Users:
The functions of our "micEcon" package [1,2] can be subdivided into three
categories:
- microeconomic demand and firm models
- sample selection models (mainly selection())
- routines for (likelihood) maximisation (e.g. maxLik(), maxNR(), maxBHHH())
(mainly used for ML estimation of sample selection models)
Although sample selection models are often used in

is.numeric
Hi,
I have a vector, which contains both strings and numbers, e.g.
> foo <- c("str1",1234,"str2",0.9876)
I want to know if a distinct element of the vector is a string or a number and
took "is.numeric", but
> is.numeric(foo[2])
[1] FALSE
because R treats the numbers in a mixed vectors as strings:
> foo

How to remove x, y labels from a plot
Hi there,
I need to plot an illustrative figure without ticks, x, y labels in R. I
