Hello,
I am trying to learn how to perform Multiple Regression Analysis in R. I
decided to take a simple example given in this PDF:
http://www.utdallas.edu/~herve/abdi-prc-pretty.pdf
I created a small CSV called, students.csv that contains the following data:
s1 14 4 1
s2 23 4 2
s3 30 7 2
s4 50
Well, you still will need Sys.getenv() to get the value of the
environment variable into R.
Are you familiar with the function named list.files() ?
This may do the job:
source( list.files( Sys.getenv('SOMEENVVAR'), pattern='myfilename') )
But I haven't tested it.

You do want outer margins, that is where the axis labels and tick marks will go
for the plots that you want.
Try: par(mar=c(0,0,0,0), oma=c(5,4,1,1)+0.1)
Then do your plots to see if that is what you want.

I've never heard of 'Portable MikeTex'. Is this (Portable) MiKTeX?
What you are doing wrong is declaring texidvi to be pdflatex, and it
simply is not. I think what you actually want is to include the

path to texi2dvi.exe

Use "Nelder-Mead" as the method in optim. This will give you the correct

If S+ has seq(length=...), that would solve any parsing problems. /Henrik

The next version of S+ will have seq_len in
it. Currently the CSAN package Rcompat contains
it.
Parsing the name seq_len can be a problem, since
S+ 8.1 still allows the use of the underscore
for assignment (it warns about its use, but
allows it). Either parse your code file in R mode
by calling

Lists have neither lines nor columns. Can you explain exactly what you have?
E.g. show us the code that created your "list"?

Suppose I have the above code, I want to know what functions and
variables have been used in the function g (in this case, f and x). Is
there a function to do so?

Hello R Experts,
How can I assign the name of a data frame with the argument of a

from SAS datasets on a

When using the subset function, writing

The OP may be interested in using low-level readBin() and writeBin()
instead. One can then either assign dimension attributes to the
object to access the data as a matrix/an array. Note that assigning
dimension attributes will probably(?) allocate a copy. If that is not
wanted, it is not that ha
