R integration with Microsoft Powerpoint
Please allow me an unusual question.
Is there any way that R can be closely integrated with a Microsoft
Powerpoint presentation? I would like to embed R calculations in
Powerpoint so that I will start Powerpoint, be prompted to enter some
parameters, and an R function will run and return values and graphs.
Thanks,
John

Missing Data Line Type?
I have a general question. Is there a setting that can be used for a
multiple line type? The situation is that I want a solid line between x
and y points but if the y point is missing, I want a dashed line type to
the next point. In other words, if point 1 to 2 exists, make that line
solid, otherwise, make it dashed up to the next existing x/y point.
Additionally, what plot type would you

Default Format for Dates?
Is there anyway to preset date formats? I have a date from a cover.dbf
that is shown as this:
> cover$FINALREPOR
[1] "2003-06-24"
The numeric value in cover$FINALREPOR is 12227. I'd rather not create
another vector to hold the properly formatted date.
When I put this in a WordPerfect merge, I want the date to be June 24,
2003. I could take care of the problem in a

Stop Warnings for Invalid Factor Level, NAs generated?
How can I stop the following warning from occuring?
invalid factor level, NAs generated in: "[<-.factor"(`*tmp*`, iseq, value =
structure(1, .Label = "12", class = "factor"))
The Label messages are for "5", "8", "12" and "46". I want the NAs to be
generated as needed.
Is this causing R to slow down by generating the warning

List and Column Names in a Function?
In this simple function, how can I pass strings for index and column names
to the function? I've posted this type of question before and received no
response.
Maybe this example will be easier to understand and troubleshoot.
ds <- function(myds, vec) {myds[[vec]]*2}
ds1 <- c(X=list(1:10), Y=list(11:20))
ds(get("ds1"),get("Y"))

Add Columns and Order for Rbind?
I am using rbind to add one list with one row to another master list. The
problem is that not all columns exist in both lists.
What methods would you recommend to reorder one list based on the column
names of another? If both sets have the same order and columns, I can
then use rbind. I can live with columns being added to the master list set
it makes the task easier using something like

Hoaglin Outlier Method
I am a new user of R so please bear with me. I have reviewed some R books,
FAQs and such but the volume of material is great. I am in the process of
porting my current SAS and SVS Script code to Lotus Approach, R and
WordPerfect.
My question is, can you help me determine the best R method to implement
the Hoaglin Outlier Method? It is used in the Appendix A and B of the fo

Windows List of Folders?
For windows, how can I list only the folders in some folder?
I was thinking that dir() and file.info() with isdir==TRUE being something
that might work.
These folders or directories are numerically named with no dot extension
names or other characters. Typically, these are 3132, 3334, ...
Here is what I tried. The last line is where I need more work.

Hello all,
I would like to know how to call sas code in R. Since I simulate data in
R and I need to use sas code (garch-t,egarch and gjr) to estimate it. I
need to simulate 500 times with 2000 obs. How I can call that code in
R.Also, how I can keep the parameters from the estimate.

Estimating EGARCH processes with R
Hallo,
I am a student specializing statistics and econometrics in germany. I know there is a way to program EGARCH-processes (time series analyses) in R.
If you are ackquainted with statistics already you know that there is nothing but a theorethical use of GARCH-Package in R. Not only because the distribution is gaussian, but also because the skewdness and leptokurthosis are not quite good

run EGARCH package on REXCEl
Hi,
I have limited experience on R and recently started using REXcel. Although I have been able to run both simple functions (like mean etc) and some complex ones (like Principal Component analysis, PCA) using RExcel, I am facing some problems while running EGARCH model. For this I have downloaded the 'betategarch' package for R to run EGARCH with student t dist. Although the package has

Egarch (1,1) with Student t distribution using rugarch

I was trying to implement Egarch (1,1) with Student t distribution using rugarch. But I was not getting any value.
Following were the commands that I was using:

ARCH-M, EGARCH
Hi,
I would like to know if there are R packages in order to fit ARIMA models
with ARCH-M and EGARCH variance specifications. I know packages tseries,
stats, nlme where I found functions : arima.sim, arima, garch. But it's
not enough for me. I need to study ARCH-m and EGARCH. Thank you very much
for your help.
Best regards,
