large dataframes to ascii
Hi R-users,
I want to convert a large dataset (from stata format) to an ascii table.
The resulting table should be a human-readable table (like CSV, or
tab-separated file or something similar). R reads the stata-file quite
easily (with some problems which are discussed here earlier), but so long I
have not found a suitable way to write it in ascii format.
Sure, there exists write.table, which

package for saving large datasets in ASCII
Hi,
I have made a tiny package for saving dataframes in ASCII format. The
package contains functions save.table() and save.delim(), the first
mimics (not completely) write.table() and the second uses just
different default values, suitable for read.delim().
The reason I have written the functions is that I have had problems
with saving large dataframes in ASCII form. write.table() essentially

problem with read.table -- example
Hi,
I have not get much response for my question about read.table for couple of
days ago. As I said, the problem is that read.delim() do not want to read
more than 51 lines of data, with longer file it reads the first column as
row names, although I have not noticed any special binary symbols around
line 51 either. This problem seems to happen with this particular file, I
could easily read in a

indexing an array
Dear everybody,
I have a following problem. I have a 3D array
lambda <- array( dim=c(N,M,M-1))
where I have to extract the elements as follows:
lambda[ 1, state[1], 1]
lambda[ 1, state[1], 2]
...
lambda[ 1, state[1], M-1]
lambda[ 2, state[2], 1]
...
lambda[ 2, state[2], M-1]
...
lambda[ N, state[N], M-1]
i.e. the result should be a 2D array, where the second index follows the
first one

bug in paste?
Dear all,
I have strange problems with paste. Actually I suggest it is a bug (I
send a associated bug report for some days ago too).
I have a vector ce0, a character vector m and I paste them together:

write.table
Hello,
When using write.table I am getting two variables pasted together (not
by choice). Has anyone else had this happen?
Specifically, I have the following:

write.table(d,file=paste('/montecarlo/forecast/off/csv/',F,'.csv',sep=''),

multinominal probit & logit
Dear everybody!
Are there algorithms for multinominal logit/probit available for R? Is it my
fault that I cannot find these in CRAN? Has somebody programmed these?

as.character.factor and S4 object containing factor

that contains "factor", all the tests indicate that it is a factor but
as.character.factor() complains of it being a non-factor...

R strings from C
Hi,
I am trying to study R internal behaviour. So long, I have not
succeeded to access the value of R strings from C.
I use:

SEXP file
)
{

}
and from the R side:

heckit / tobit estimation
Dear All,
we (Ott Toomet and I) would like to add functions for maximum likelihood (ML)
estimations of generalized tobit models of type 2 and type 5 (*see below) in
my R package for microeconomic analysis "micEcon". So far we have called
these functions "tobit2( )" and "tobit5( )".
Are these classifications well known? How are these functions called in other

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

lapply-related question
Dear R-gurus,
I would like to use a lapply on a kind of "bivariate" problem. I have
a vector and a list, components of which are vectors, e.g.
vec <- c(1,2,3)
lst <- list(1, c(2,3), c(4,5,6))
I want to apply a function to each component of the list, using the
corresponding component of the vector as a parameter. E.g. I want a
list in the form
list(lst[[1]] + vec[1], lst[[2]]

issues with dev.new avoiding RStudio plot device on unix?
Sorry, should have given more background. x11 works fine on all my
systems when called by x11(). I'm the maintainer of a package that uses
the animation library, which has performance issues when used with the
RStudio plot device. But if you call plot.new() when using RStudio, you
get an RStudio device, not the standard device for the platform because
it overrides the device option.
