Hi Miki and Chunhao,

Hi all,
I wish to do a random subset (i.e. 200 or 300 points) from a dataset, but I
don't find the right code in R.
Thanks for help

Just to let everyone know: John Chambers R book is no longer at
pre-order status on Amazon which is a good thing. The only problem
is that now it is temporarily out of stock. There must have been many
pre-orders so now I'm kicking myself for not having done that.

Hi Anna,
Thanks for your reply and suggestions. I'm trying something different, based
on regression this time, albeit giving similar problems. I want to regress a
single column in a matrix with each other column in the same matrix, and o/p
the intercept and slope coefficients to a results matrix.
Hi,
check
?sample
n <- 200
mydata.set <- rnorm(10)
my.random.subset <- sample(x=mydata.set, size=n, replace=TRUE)
my.random.subset
I hope this helps,
Roland

Hi,
I find that a typical workflow for me looks something like this:
1) import some data from files
2) mess around with the data for a while
3) mess around with plotting for a while
4) get a plot or analysis that looks good
5) go back through my history to make a list of the shortest command

Hi all,
I have this string "year" and integer 2008 (both are inputs from the
user), and I would like to make a variable called "year2008" that will store
a vector of numbers. Does anyone know how to do this?
Also, if the user later input "year" and "2008", how do I treat this as a
variable;
Well, in this case I don't think my original code would have helped much...
So, I've rewritten as below. I want to perform regression between one column
in a matrix and all other columns in the same matrix. I have a for loop to
achieve this, which succeeds in exporting intercept and slope coeffic
