max() and min() functions not found
....rm = na.rm)) :
nessuna funzione interna "min"
which, as you may have guessed, means 'no internal function "min" '. The
same happens for max().
Maybe this is a bug in the new release, or maybe I'm missing something?

simple parallel computing on single multicore machine
...seen some talk here on making R multi-threaded and the like, but
this is much simpler. I am just a curious useR, so don't bother if you
don't have time, but maybe you can point me at some resource, or just
say "this is nonsense"...

Quarterly data in PLM package
Dear all,
Does anyone know if the PLM package (to run Panel Data Analysis) accepts quarterly data?
The package vignette and documentation only use annual data -and the only time index available seems to work for years.

Panel Data Analysis (PLM) - Fixed Effects - "cannot allocate vector of length"
Hello to all on the list,
I'm trying to estimate a fixed effects model from a large (unbalanced) panel
data set.
I have no problems when using only an individual effect or only a time
effect, but I get an error message when I try for a "twoways" effect. Here
is some of the code:
paneldata27 is the entire panel data set:
> dim(paneldata27)
[1] 1178831 8

plm random effect: the estimated variance of the individual effect is negative
...t with 0; 'plm's is to let the estimation fail, issuing a warning. You
can try a different 'random.method' which may, or might not, solve the
problem, depending on your data.
Hint: a random effects model with sigma_mu=0 is a pooling model.

estimating probit models
Dear all,
I am looking for a convenient way to model a binary choice variable in R.
Would you suggest glm() with family=binomial(link=probit))? Is there something more focused on that kind of analysis? Or am I plainly wrong?
Cheers and thanx for your answers

presentation of software
Hello,
I am considering giving a talk at my university
on R to (mostly) academics. There wouldn't be any
statisticians, but professors from mathematics,
psychology, economics, etc. who do use some statistical
software in teaching and/or research, and have an acquaintance
with procedures and graphics used in statistics. Has anyone
given such a talk to a similar audience? If so, I would be

statistical tests under serial dependence

I would like to know if there are already programmed statistical tests

Thank you very much

You might use traceback() to better identify the problem, and/or send a

Data import/export is the nastiest step in any stats program, hold on

you don't have enough RAM (although from your post it is impossible to

plm package index
Dear all,
i just wonder if there´s a way to use a two column time index field in plm package.
the manual says the following concerning data indexing:
a character vector of length two containing the names of the individual and the time
index,
What would y´all do with a quarterly dataset that contains one column for the period and one for the year. Do I have to convert it to one single date

Package plm & heterogenous slopes
Dear r-helpers,
I am working with plm package. I am trying to fit a fixed effects (or
a 'within') model of the form
y_it = a_i + b_i*t + e_it, i.e. a model with an individual-specific
intercept and an individual-
specific slope.
Does plm support this directly?
Thanks in advance!

Three-way Panel Data Analysis
Dear R users,
I have panel data on the amount of money spent by travellers from 8 origin
countries in 4 destinations. I would like to carry out analysis for
destinations, origins and time. However, it seems to me that the package
"plm" can only esitmate two-way panel data (indexed by a two-dimensional
array). Any suggestions would be greatly appreciated.
Thank you.
