Understanding R's "Environment" concept
Hi all, I am trying to understand the R's "environment" concept
however the underlying help files look quite technical to me. Can
experts here provide me some more intuitive ideas behind this concept
like, why it is there, what exactly it is doing in R's architecture
etc.?
I mainly need some non-technical intuitive explanation.
Thanks,

Finding length of unique numbers in a vector
Hello there, would you please look into my codes? Here I have following:

How can I do that?
Thanks in advance

specific range. However presently, I have something related but
different problem. Suppose I have a numeric vector. Now take an

developed package, however wondering whether there could be any
simpler way to do so. In writing R extension it is advised to go
through Sweave route, however I have already got a big pdf file and
want to use this as package vignette.
So far I have manually created the inst/doc folder in the main package
skeleton, and put that file

Building latest version of package
Hi
I have a package which was built using R 1.9.1 and everything worked
fine. I recently upgraded to R 2.0.1 and tried to re-install my package

R CMD check: Error in .C
Function/file names are hypothetical. Say I have written myfunction.R,
which calls myfunction.c via .C("myfunction", ...).
I've compiled successfully myfunction.c via R CMD SHLIB myfunction.c
in the terminal. Then, in the R console:
dyn.load("myfunction.so")
source("myfunction.R")
test <- myfunction() # works fine
So everything is in order, myfunction works

Making a Package
Hello.
I have what I know to be a simple question, but never having done anything like this it is
pretty tough.
I'm trying to write an R package. I have a collection of functions that I loaded into R and
then used package.skeleton(). After editing everything in the resulting folder, call it
NewPackage, I tried to follow along with some instructions I found for Windows users.

Questions on package creation
I have some questions about
1. nomenclature,
2. recommended file locations and
3. overall procedure related to creating packages.
To the extent that it matters, examples here relate to Windows XP
R 2.0.1 beta.
The questions are interspersed and prefaced with ***.
My understanding is that there are actually 6 forms of a package
that one should use in package development:

Example input data with example output using relative pathway in vignette of R package?
I'm putting together an R package. I would like to show example code in the
vignette, where example data files (included in the package) are used to
generate an (example) output file.
I read about using example data in Hadley Wickham's post (
http://r-pkgs.had.co.nz/data.html), and believe I should keep my example
data as raw data, as it must be parsed to generate the output.
So, I

I have question regarding package installation.
What is the difference between check, INSTALL, build and
