replacing values in a vector
Hi all,
there is a vector v with several NAs. I want to create a new vector n of
the same length as v and the same NAs as in v and tried this:
n <- vector(length=length(v), mode="numeric")
replace(n, which(is.na(v)), NA)
but this does't work, all values in n are 0. What went wrong?
Thanks, Sven

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

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,

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:

R:how to separate stuff?
Thanks for your help on moving files from
S+ to R and on attaching directories.
If attaching directories is NOT possible in R,
is there any other way to separate
objects into different folders or something similar?
For example, to keep user functions for multivariate
analysis in a different "place" than user functions on
time series, or to keep data objects of project_1

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.

union of lists
Hi there,
Given 2 lists of integer vectors, i.e.:
> lista1
$"1"
[1] 1 34 5
$"2"

$"3"
[1] 3 10 15
> lista2
$"1"
[1] 1 5
$"2"
[1] 2 1
$"3"
[1] 3 10 29
I want to obtain the union of both, defined
as the union of the vectors, that is

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

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

Subseting in a 3D array
Hi!
I have a 3d array:
> dim(ib5km15.dbc)
[1] 190 241 19
and a set of positions to extract:
> ib5km.lincol.random[1:3,]
[,1] [,2]
[1,] 78 70
[2,] 29 213
[3,] 180 22
Geting the values of a 2D array
for that set of positions would
be:

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.

readline() to vector
Hi!
I'm trying to use readline() to ask for xlim() and ylim() values
for a subsequent plot. I'm doing:
lim <- readline("Enter xlim and ylim values: ")
then would like to use the values in lim for a plot:
plot(etc, xlim=lim[1:2],ylim=lim[3:4])
The problem is that lim is a character,i.e.,
"10,20,-10,50"
or
"c(10,20,-10,50)"
depending on the input to
