Where to find old R packages?
What happens to old R packages? Is there a place where they are stored like
an archive? I'm looking for a package called ScanoR that doesn't exist
anymore on CRAN, the author doesn't exist anymore... I had made copies of
all packages (fearing that some might be "taken off the air" but

in 2007). Any

R CMD build when the package name is different from the directory name
...;R CMD build" in future releases?
Do I have to change the file name and/or the name of the base directory before
uploading the package to CRAN?
I use R version 2.3.1 (2006-06-01) on i686-pc-linux-gnu.
The same happens with R version 2.4.0 RC.
Thanks,
Arne

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?

systemfit - SUR
Hello to everyone,

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

make apply() return a list
...[,2]
[1,] 2 2
[2,] 5 5
$"3"
[,1] [,2]
[1,] 3 3
[2,] 6 6
This exactly does what I want and really speeds up the calculation, but I
wonder if there is an easier way to make apply() return a list.
Thanks for your help,
Arne

License for including datasets in packages
...did not find any license information.
Whom do I have to ask wether I am allowed to put these data in a GPLed R
package? (Mr. Mroz, Mr. Greene, STATA, University of Michigan (PSID), . . . )
@John: Do you have any license information on these data?
Thanks,

R CMD check warning on predict.systemfit
...he same as in
"predict.systemfit". Thus, I think that our way to specify
"predict.systemfit" might be OK in spite of this warning.
What should I do? Can I ignore this warning?
What will Kurt answer when we submit it ;-) ?
Best wishes,
Arne

Does anybody have a better suggestion?
How is this implemented in other software packages?
What do you think is the best option?
