Hi David,
Thanks for your reply. The package is Kernlab. I agree with you when you
mention that R didn't like the structure of the testSeq object but I can't
figure out why.
Here is the output for "dput(testSeq) and str(testSeq). Any insight that you
can see would be really helpful to me.
Thanks
Hi Steve,
Thank you so much for the reply. The response to your queries are:
What do these commands return over your data?
1. is(train500)

2. is(train500$class)
--> "NULL" "OptionalFunction" "output"
3. is(train500[1,5])
Thanks, but I kind of new this way already and it doesn't seem an optimal
thing to do.
What I was looking for is to pass some argument in 'merge' itself
which doesn't change the ordering of 'x'. Or, more than that, I am
interested in knowing that why is it changing the o

Thanks.
BTW, if i have three functions, a,b and c. I only want the two functions
"a" and "b" to be exported for use and "c" is only used by myself because
it is not very stable.
How to set this?
Thanks a lot.

Hi there,
You can add a order column on x or y and after use this field to order z.
Like
z<-z[order(z$orderfield),]
To generate a order on x or y you can do something like
x$xorder<-1:nrow(x)

Dear Jeff,
Take a look at the following example. It may get you started.

x1 <- rnorm(100)
x2 <- runif(100)
x3 <- rpois(100, 2)

y1 <- 3 + 2*x1 + .5*x2 + x3 + er

Hi,
I have multiple responses y1, y2, .., yn, and would like to do linear
regression for each of them with x1, x2, ..., xm. Instead of doing
regression n times, it it possible to do it all at once?
I tried lm(y1+y2 ~ x1 + x2 + x3) and lm added y1 y2 and then did the
regression.
thanks

I am afraid that although in same literally, they are indeed different
functions: as.Date.POSIXct and as.Date.POSIXlt. But I am not sure why
they are designed like this, which causes the confusion as you
mentioned.
