You want to aim to write a family for R, not find the equivalents of S

In particular, an R family has several components which an S family does

If 16063 were an integer multiple of 217 you could do this in two steps;

However, 16063 is not a multiple of 217, so I don't know what you want to do

Your surest bet is to look into S+, not R, since the former does
'integrate' with Microsoft applications. To what extent, I don' know.
This is a desirable feature (IMO) and a reason to use S+ rather then R
(already discussed in different thread).

Since the power of the t-test decreases when there are

What does class(r1) give you ? If it is "data.frame", then try
exp( diff( log( as.matrix( df ) ) ) )
BTW, I made the assumption that both x and y are positive values only.

Hi,
I am newbie in R. I have R installed on Solaris machine and I am connected
to Solaris machine from Windows using telnet. I want to create png image

hi all,
I need to normalize a function, did something exist in R who can do it for me,
instead of integrate the function then divide it by the result?
thks, i'm sorry i didn't found any information in the documentations and
statistic vocabulary in english is a pain for me.
My guess is that you have two data points which are very close together.
The normal way out is to included a nugget effect in your model, but it
can also be appropriate to leave out one of a pair of points.

days() is not part of R, and I guess from your subject is part of chron.
Its help page does not say what it actually does, but my guess is that it

It probably is not a problem to leave hyperthreading on: we found little
performance difference on a P4 either way.
The Windows task manager is misleading, as `50%' is about as much as a
P4-class processor with hyperthreading can actually deliver.
