Updating R version
A quick question. I am trying to understand how I could move the installed
packages in my R 2.3 version to the newly installed R 2.5 version, without
having to install all the packages again. I copied the files under the old
library subdirectory to the new library subdirectory. But still the newer
version is not recognizing the packages that were copied over.
Thanks.

using non-ASCII strings in R packages
...t OK to include them in Windows-1250 encoding (default for Polish locale, as far as I know)? I believe this problem is frequently confronted for other "non-latin1" languages. If it is not the way to go, I would be very grateful for suggestions.
Thanks in advance

sink with R-code
I have the same question that Eusebio had:
Is there a function similar to "sink" that redirect also R code to a
file that
is:
sink("R001")
x <- c(2,-6,-4,8,5,4,1,3,4,-9,0,1)
A <- matrix(x, ncol=3)
A
A.prima <- t(A)
A.prima
dim(A)
dim(A.prima)
sink()
create a file "R001" with contents:

newbie question
Hello to all.
My name is Michal Bojanowski, I'm a Sociology student at Unversity of
Warsaw. Recently I've started to learn R when I've found myself frustrated
because of inflexibility of SPSS and other "user-friendly" statistical
software. As I said, I'm new here, so my question is very simple:

I have a list called dataHP which has 30 elements (m1, m2, ..., m30).
Each element is a 7x6 matrix holding yield data from two factors

instance, the element 20 is:

interactive menu in scripts
Hello, I would like to make my R script more interactive. Well, I want the
script to work like this:
I run the script from R Console and it offers me some options (press 1 for
something, or press 2 for something else). After pressing 1 or 2, do
corresponding procedure.
I am not able to find out how to do this. I guess the functions menu() or
switch() are the keys, but I didn't manage to use

Two-argument functions in tapply()
...ot a multiple of shorter object length in: x * w
2: longer object length

What is the right way to get the results (how to use 2-argument function in
tapply()), or maybe there is another simple way to do this
ThankYouInAdvance

inconsistent behaviour of add1 and drop1 with a weighted linear model
Dear R Help,
I have noticed some inconsistent behaviour of add1 and drop1 with a
weighted linear model, which affects the interpretation of the results.
I have these data to fit with a linear model, I want to weight them by
the relative size of the geographical areas they represent.

rearranging data frame rows
Hi All,
I have two data frames. The first contains data about a number of individuals,
coded in the first column with a name, in an order I find convenient.
The second contains different data about the same indivduals, in a different
order. Both data frame have the individual names in the first column.
I need to reorder the second data frame so the rows are rearranged in the same

script window background and text color (PR#13446)
Full_Name: alexios galanos
Version: 2.8.1
OS: windows/vista
Submission from: (NULL) (81.100.160.71)
While the script editor now respects user preferences for the background color
in 2.8.1, it does not do so for the user text color defaulting to black. So my
preference of having for example black background with green text fails (it is
all black) in the script editor (the console is ok).
