adding regression curve to xyplot
Dear R-listers,
It seems that predict() behaves differently within panel.xyplot. Am I
doing something stupid?
Thanks,
Carlisle
First, without xyplot():
> lmtest <- lm(t~s,data=subset(P100,whichLon100==1 & whichLat100==1))
> lmtest
Call:
lm(formula = s ~ t, data = subset(P100, whichLon100 == 1 & whichLat100 ==
1))
Coefficients:
(Intercept) t

need help with smooth.spline
Dear R listers,
When using smooth.spline to interpolate data, results are generally
good. However, some cases produce totally unreasonable results.
The data are values of pressure, temperature, and salinity from a
probe that is lowered into the ocean, and the objective is to
interpolate temperature and salinity to specified pressures. While
smooth.spline provides excellent values at the

help.start search
Dear R experts,
When using R 2.1 under Red Hat Enterprise Linux 4 with Mozilla 1.7.6 as
browser, help.start() almost works correctly. When I follow one of the
search result links everything is fine, but when I go back to follow
another link, I find them all inactive. So I have to redo the search.
Any suggestions?
Thanks,

k-d tree for loess
I am exploring the use of loess for oceanographic applications and would
like to plot the locations (longitude and latitude) points where the models
(salinity~temperature*longitude*latitude,parametric="temperature") are
fitted. Chambers and Hastie(1993) explains the locations are nodes of a
k-d tree. but I cannot find anything about accessing this information. It

matrix manipulation
Dear Rlisters,
I'm writing to ask how to manipulate a matrix or dataframe in a specific way.
To elaborate, let's consider an example. Assume we have the following
3 by 4 matrix A with elements either 0 or 1,
0 1 1 0
1 0 1 1
0 0 0 1
>From the original matrix A, I'd like to generate a new matrix B satisfing

Help with Clustering Techniques in R
Greetings RListers,
I have a data set containing two types of outcomes; success and failure.
Associated with each outcome are 12 different measurements. I'm trying
to find out, for example, if some of the 12 measures are associated more
with success or failure or, if there's any relationship at all between
the measures and the outcomes (success or failure).
I don't have (as yet)

How to increase precision to handle very low P-values
Hello, Rlisters
I have to compute p-values that are on the tail of the distribution,
P-values < 10^-20.
However, my current implementations enable one to estimate P-values up to
10^-12, or so.
A typical example is found below, where t is my critical value.
########### example - code adapted from Rassoc #######################
rho01 = 0.5
rho105 = 0.5
rho005 = 0.5
t = 8

R OS X panther? (PR#5529)
I have just used the RAqua.pkg to install R, and it doesn't work! I
have Mac OS X 10.3, and the old version of R works OK, but the .pkg
thing installed, and then when I double-click on the "StartR"
application nothing happens. Nothing at all, no little icon bobbing up
and down in the dock, just nothing. What have I done wrong? I didn't

overlapping plots
How to combine three plots so that they partially overlap? As the data
on all three are near the left side and top, it would be nice to draw
the first, shift axes down and to the right and draw the second, and
shift again to draw the third.
I could shift the data for the 2nd and 3rd plots and construct their
axes by hand, but it would be great if R has an easier way.

Adding units to levelplot's colorkey
How to add units (e.g. "cm") to the color key of a lattice levelplot?
The plots looks fantastic, but it would be nice to indicate somewhere
near the end of the color key that the values associated with its colors
are in centimeters or some other physical units.
The only thing I find is the possibility to specify the labels so that
one explicitly includes the units. That leaves

coupled statistical models
Can someone point me to the appropriate functions for
fitting multiple statistical models that are coupled
to each other.
The data are measurements of salinity s and temperature t
at stations id and pressures at p as well as surface elevations h
at stations id. The problem is, for any new station, to estimate
s at all p, given t at all p and given h.
If h is ignored, the for each p, there

2d plotting and colours
Hi!
I am new to R just 3 days in it and i apologize if my questions seem very
trivial and consumed your valuable time.
I am coding in perl and i stumbled upon R regarding plotting good
statistical graphs.
I tried the kmean clustering for a large matrix ,say > 150 * 150 . I tried
the example code given in the tutorial to perform 2d plot
# i ranges from 2 to 10

Oceanographic lattice plots?

urgent response needed
Dear Rlisters:
I would personally disencourage to answer this letter and ,in my
opinion, I would advise to reject from the list further mails like this one.
They scam people through their VISA numbers. These emails from Nigeria are
sadly familiar to an association that I belong (the Institute of Food
Technologist, IFT). We received letters from the IFT telling that they got
somehow access to the
