se's and CI's for fitted lines in multivariate regression analysis
I?m entirely stumped on this particular issue and really hoping someone has
some advice for me.
I am running a covariant model in lm I would like to give the standard
errors or the confidence intervals for the fitted lines. I?ve been using the
dataset OrangeSprays where I want lines for each level of treatment over the
covariant ?colpos?. I?ve been able to calculate intercepts and slopes for

barplot and map overlay
Hi,
I wonder if it is possible with the graphics package to overlay one or several plots
(barplots, for example) over a map. Data for the map is in a data frame with the
latitude and longitude coordinates, and then:
> plot(map$long, map$lat, type ="l")
produces the map. I want to put each barplot in specific locations on the map, namely
at the center of "statistical

boxplot - code for labeling outliers - any suggestions for improvements?
Hello all,
I wrote a small function to add labels for outliers in a boxplot.
This function will only work on a simple boxplot/formula command (e.g:
something like boxplot(y~x)).
Code + example follows in this e-mail.
I'd be happy for any suggestions on how to improve this code, for example:
- Handle boxplot.matrix (which shouldn't be too hard to do)
- Handle cases of complex

plotting arrows with different colors and varying head size
Dear list,
I would like to plot arrows with different colors according to arrow length, and also (if
possible) with head size proportional to arrow length. The idea is to make a quiver-like plot of
matlab with wind speed data.
So far, I´ve been able to use different colors, but I need to find a more efficient way to recode
arrow length intervals into colors. On the contrary, I can't define

How to custom the tick and type in bwplot
Dear R users
I use bwplot to plot some figures. There are two troubles:
1. How to change the dot of the mean to a line, like the style in boxplot
2. How to hide some tick marks. For example, I have seven tick: A, B, C, D,
E, F, G,
but I want show four marks: A, C, E, G on the x-axis.
Thanks!

coping with a warning in if()
Hi,
I'm sure this one is very easy....
I am trying to write a function where one of its arguments has two posible (strings) values,
defaulting to one of them if none is specified. My problem is that when evaluating the function
the following warning is produced:
"the condition has length > 1 and only the first element will be used"

Boxplot.stats
Junto con saludar,
Quer?a saber si los que han usado boxplot.stats, saben como ubicar los resultados que arroja como "out" (outliers) directamente en la base de datos, ya que, muestra los resultados en valor de cada dato at?pico.
Por ejemplo, estoy usando una base de datos con 300 datos y 10 columnas, en este caso estoy buscando los datos at?picos de la columna del precio de x

Adjusting x/y text labels for a bwplot using cex.lab
Searched for this and found some help, but I still can't figure it out.
I have trying to enlarge the x and y labels on my box plot. I understand
that you can do this using "cex.lab", but it does not seem to be working for
me. I must be adding it in the wrong spot. Any help would be greatly
appreciated. Here is my code:

zero center a group of variables
*This message was transferred with a trial version of CommuniGate(tm) Pro*
A simple question, perhaps to simple, but I am new to R:
For a data frame with k variables and n1+n2 observations (two
groups) how can i substract the group means for every variable, so
both group variables become centered to mean zero?

manipulating text to generate different formulas to use in nls()
Hello,
In doing a series of non-linear estimations of a function which is a sum of a varying number
of sinusoids, I would like to "autogenerate" the arguments needed by nls() depending on that
number.
For example, when there are two sinusoids:
> nls( y ~ mu + A1 * cos(2*pi*f1*x - P1) + A2 * cos(2*pi*f2*x - P2), data = some.xy.data,
start = list( mu=some.value0,

Reading biplot function's source code

Excuse me for this silly question, but after searching the

I have installed the mvbutils package, and tried:

which only gives me:

with no further details....

turn off selected axes in bwplot
I want to turn off selected axes in bwplot. I would like to only have the bottom axis drawn, with the others off.
I have a series of bwplots that I want on one device, like this:

p2<-bwplot(x2,box.ratio=.1)
