Hi Max,
Thanks for the suggestion, that's exactly what I was looking for. Thanks
again.

Hi,
I have added a second y-axis via axis() to a plot.
Then I tried to add an y axis title.
But the axis() function seems to have no argument like ylab.
and if I add a title with title() the text is centered at the first
axis, not the second defined one.
Is there a way to add an

Hi All, would appreciate an answer on this if you have a moment;
Is there a function (before I try and write it !) that allows the input of a
covariance or correlation matrix to calculate PCA, rather than the actual
data as in princomp()

Recently I got introduced to two packages: {seewave} and {audio} .
Turns out they both have a tool to call a system audio tool, and in both
cases the name of the tool is play(). Naturally these two tools do
slightly different things with different arguments.
So, what should a user do, and

Charlotta,
I'm not sure what you mean when you say simple linear
regression. From your description you have two groups
of people, for which you recorded contaminant concentration.
Thus, I would think you would do something like a t-test to
compare the mean concentration level. Where does the

Hello R users,
Can someone tell if there is a package in R that can do outlier detection
that give outputs simiilar to what I got from SAS below.
Many thanks in advance for any help!

I must disagree with both this general characterization of the
Wilcoxon test and with the specific example offered. First, we ought
to spell the author's correctly and then clarify that it is the
Wilcoxon rank-sum test that is being considered. Next, the WRS test is
a test for differences
First of all, sorry for my typing mistakes.
Second, the WRS test is most certainly not a test for unequal medians.
Although under specified models it would be. Just as under specified
models it can be a test for other measures of location. Perhaps I did not
word my explanation correctly, but I
Dear R users,
From the code below, I try to compute y value. (In fact, y looks like a
trapezoid)

Hi Charlotta, to be more constructive toward your goal. If you bootstrap the
regression when the regression is ill-specified, the bootstrap may not help
you. Further, a test as difficult as a regression does not seem to be
necessary in your case. A t-test if your dependent variable is
what are you looking for? I am not familiar with SAS as I am a poor
scientist. I am not promising anything, but if you were to tell me
what you wanted - method etc. I may know of a package or something
that would work.

understand the above results.

The Wilcoxon rank sum test is not plain and simple a test equality of
distributions. If it were such, it would be able to test for
differences in variance when locations were similar. For that purpose
it would, in point of fact, be useless. Compare these simple
situations w.r.t. the WRS:
