R newbie example code question
Sometimes I print out a package
and read about it and there
are sometimes nice examples
that I would like to run myself.
Is there a way to bring them
into R from the package or
are they only meant to be typed
in manually ? If manual is the
only way, that's fine. I was
just checking whether there was
a quicker way. Thanks.

R newbie configuration
I think I did enough reading on my
Own about startup ( part of the morning
And most of this afternoon )
to not feel uncomfortable asking
for confirmation of my understanding of this startup stuff.
Obviously, the startup process is more complicated
Than below but, for my R newbie purposes,
It seems like I can think of the startup process as follows :
Suppose my home directory =

FW: R and read.irts
I have never worked with R before so I am
sorry if this is a bad question but I've
tried and tried ( all day ) and I can't figure this
problem out. I have the code below and I included the
data file as an attachment.
The code works in term of reading in the data
correctly but when the graph gets
created, the xaxis is really strangely/incorrectly
labelled. I have been trying
to understand

a series of 1's and -1's
Does anyone know of a simple test
in any R package that given
a series of negative ones and positive
ones ( no other values are possible in the series )
returns a test of whether the series is random or not.
( a test at each point would be good but
I can use the apply function to implement
that ) ?
thanks.

newbie R question
I'm sorry to bother everyone with a stupid
question but, when I am at an R prompt in Windows,
is there a way to see what packages
you already have installed from the R site so
that you can just do library(name_of_package)
and it will work.
I've looked at help etc but I can't find
a command like this. Maybe there
isn't one which is fine.

R and read.irts
I thought r-help let you
attach asci files but
I don't think it does now
so below is a sample of my data set.
Thanks again.

ESS and Emacs
I have been using the document written by John Fox titled
Sn Introduction to ESS + XEmacs for Windows
Users of R.
It's a very nice document and
I went through it carefully but I got
an error when I finished it and launched XEmacs.
The error is "cannot open load file : ess-site".
So, I did more investigation
and it seems like there is a folder

Using R in a production /real time windows environment
I just had a question for anyone who has done this.
I am currently using R in a research environment
but I was wondering if anyone has had experience using
it in a production/real time environment where data
is coming in quite quickly ( every second or so ) and
things have to be calculated quickly and sent
back out to some kind of front end.GUI environment
Was this successful or difficult and

brown, durbin , evans ( 1975 )
Does anyone know where
I can get R code for plotting
the Brown , Durbin
and Evans cumsum
procedure ( 1975 ) ?
I wrote my own code but
I am a little worried
that my confiodence bands
may not be correct ( I find the formula
in the original paper confusing and S+Finmetrics
has a formula but that formula implies that
there should be 4 lines as far as I can tell ) so
I would like to see someone

I think simple R question
I have a vector x with #'s ( 1 or -1 in them ) in it and I want to
"mark" a new vector with the sign of the value of the a streak
of H where H = some number ( at the next spot in the vector )
So, say H was equal to 3 and
I had a vector of
[1] [2] [3] [4] [5] [6] [7] [8] [9] [10]
1 -1 1 1 1 -1 1 1 -1 -1
then, I would want a function to

I think not so hard question
I'm sorry to bother this list so much
But I haven't programmed in
A while and I'm struggling.
I have a vector in R of 1's and -1's
And I want to use a streak of size Y
To predict that the same value will
Be next.
So, suppose Y = 3. Then, if there is a streak of three
ones in a row, then I will predict that the next value is
a 1. But, if there is a streak of 3 -1's in

complex matrix manipulation question
I've done stuff like this before but
it's been a while and I'm stuck.
Suppose I have a matrix with one
column x and another column y
and both are numeric and let the
row index of the matrix be i
Starting at index i ( i would equal on the first iteration )
when the cumulative sum of x_i+1 - x_i
is greater than W = some constant, I want to mark that spot in the
row, call it i^* and

newbie where to look question
I don't want to bother anyone
with specific questions
because I am a R newbie and
I see that there is TON ( emphasis on
Ton ) of documentation
out there but could
someone just tell me the
best placed to look/read
for learning about ( for R-2-2.1 in Windows )
.Rprofile
.REnviron.
.Rdata
.First function ( analogous to the one in Splus ).
