Hello
Your attachement didn't seem to get through.
You can simulate data using rnorm() or any of the r*() functions [1].
You can also use it to add noise to a custom function that you use to
generate your specific data.

My prior solution was not correct.
If the idea is to combine each row of x with each row
of y then convert the matrices to data frames and
perform and outer join with SQL like this:
library(sqldf)
X - as.data.frame(x)
Y - as.data.frame(y)
as.matrix(sqldf(select * from X, Y, method = raw))

I highly suggest to rethink your problem in a way that you store the

Hi all,
We are looking for a tutor who could teach me statistical learning and
data-mining using the book:
The Elements of Statistical Learning: Data Mining, Inference, and Prediction
Please drop me a line if you are interested. Thank you!

Sorry,
That worked.
However, is it possible to single out specific boxes and change their colour? I
want the four graph headers in
the top right of the trellice to be different colour to the rest.
Thanks very much

Dear All,
I have a piece of text that I want to append to a text file at the
beginning of the text file.
I have thought about using cat() with the option 'append=T', but the
appending, in this case, is done at the bottom of the text file. Any
ideas?
Thanks in advance,
Paul
Dear R-users,
I am trying to create a model using the NLS function, such that:
Y = f(X) + q + e
Where f is a nonlinear (Weibull: a*(1-exp(-b*X^c)) function of X and q is a
covariate (continous variable) and e is an error term. I know that you can
create multiple nonlinear regressions where x

Hi All,
I'm trying to run nls on the data from the study by Marske (Biochemical
Oxygen Demand Interpretation Using Sum of Squares Surface. M.S. thesis,
University of Wisconsin, Madison, 1967) and was reported in Bates and Watts
(1988).
Data is as follows, (stored as mydata)

Manuel,
Thanks for the reference. I printed it out and read through it this
morning.
I think I'm going to take a gls approach. I've spent the last couple weeks
reading about spatial autocorrelation, and found that the world of SAC is
large, complex, and requires more time than I currently have.
I want to draw lines using a matrix with the X-axe on the first column, and
the the Y-axe on the second column.
These lines have to link the n points of a graph, so they are n-1, but the
resout using these two commands:
X - matrix(scan(MaxInterEdges.R,0), ncol=2);
I finally found some time to look at it:
Yes, it does not work properly for angles 180 degrees. Will try to
find a fix and make a new release soon.
Best wishes,

Hi everyone,
I'm building a website (http://yourpsyche.org) using Jeffrey Horner's
awesome Rapache module. I want to take user input, and pass it to an R
script. At first I was simply using if else statements, but after a
while I had so many nested if else's in my code that my head was
spinning.
Great! Thanks again!

Hey guys,
Hi Ista -
I've had success using the do.call function with RApache
do.call(func, arglst)
where 'func' is the function you desire to use, 'arglst' is a list of arguments.
You may need to do some cleanup of the arguments using evalq()
function (so that numbers are treated as numbers, for
