R 1.1 congrat; undocumented behaviour of recordPlot
Hello,
first, I'd like to congratulate the core team to the new R version 1.1. I
think it's a great update, with glimpses into an even greater future
(tcltk!).
While playing around with the new functions (on Win 95), I found the
following:
As the documentation states, when I generate a plot and save it with
recordPlot, I can regenerate it by printing the variable:
> plot(1:10)

Re: [R] R 1.1 congrat; undocumented behaviour of recordPlot (PR#578)
I think this is pretty certainly a bug, so I'm cc'ing this to r-bugs.

list of all objects - just being curious
Hello all,
to obtain a list of all objects in all search paths, I've found the
following to work:
> biglist <- sapply(1:length(search()), objects)
This more obvious one, however, does not work:
> biglist <- sapply(search(), objects)
Error in pos.to.env(pos) : invalid argument
Still, search() gives

recordPlot() on non-interactive graphics device?
Hi.
Q. Is there a way to record a plot using grDevices::recordPlot()
without opening an interactive (=visible GUI window) graphics device
(not even for a flash of a second)?
Related: help("recordPlot", package="grDevices") says:
"These functions record and replay the displaylist of the current
graphics device."
Is the intention that recordPlot() should be able to

How to create a data.frame "like" another, but longer?
Hello,
does anyone know of a quick way to create a data frame "like" another, but
with more rows?
What I'd like to do is this:
if mydata is a data.frame like
a b c
1 TRUE yes
2 FALSE no
3 TRUE yes
I'd like to get mydata2 with the same column names and column types, but
without the values and with more rows.

Type III Sums of Squares?
Hello,
I'd like to propose an extension to the function summary.aov.
In Splus (2000, I don't know about other versions), summary.aov allows a
parameter ssType to be set to 1 or 3 (defaults to 1) to choose the type of
Sums of Squares.
I know I can get Type III SS in R with drop1(model), but including the
functionality into summary.aov would, in my opinion,
- yield a more usable table

newbie questions: accessing functions globally
How can I access a function created in one data directory in another? I
have been sourcing the text file that contains the function each time I go
to another data dir. This is cumbersome, and I suspect there is a way to
make functions global.
Thanks in advance,

density ellipses?
Hello,
has anybody written a function to plot density ellipses (95%, 99% or
anything) in a scatterplot? I found nothing in any package, nor in the list
archives.
There does seem to be a contributed package "ellipse" for S-Plus (on
S-Archive), but it does a lot more than what I would need. Still, if anybody
ported it to R, I'd be grateful for a link. I'm a bit afraid to try the

MacOS X: Packages KernSmooth and cluster won't compile
Hello,
I'm using R 1.40 on MacOS X X.1.2 (installed via the fink package manager).
To upgrade my installed packages, I tried to use update.packages() today.
All went well for most packages, with the exception of KernSmooth and
cluster. In both cases, libraries were not found although I think they are
present.

Post hoc tests
This is only partly an R question, but this seems a good place to ask.
Like many, if not most, statistics programs, R has no post hoc tests
for Kruskal Wallis or Friedman, and as far as I can make out they are
not available in any of the R packages. I would be grateful if someone
could point me in the right direction if I am wrong.
As I said this is not uncommon. Parametric Anova procedures

recordPlot usage: add snaps to a list.
I have trouble understanding the R list object and how to add objects

works fine to make the pictures:

Estimating Weibull Distribution Parameters - very basic question
Hello,
is there a quick way of estimating Weibull parameters for some data points
that are assumed to be Weibull-distributed?
I guess I'm just too lazy to set up a Maximum-Likelihood estimation...
...but maybe there is a simpler way?
Thanks for any hint (and yes, I've read help(Weibull) ;)

Using a zero-finding routine in R
Hello all!
I'd like to use a routine in R to find the zero of a function (like
Newton-Raphson, Broyden, etc.)
In the manual, I found a reference to Newton-Raphson method in the
"qr" function, but I simply wonder how I could use it to implement such a
method.
