How do I change plot colors in bwplot
Hello,
I'm using bwplot to make a few plots. The plots are exactly what I
need, but are coming out with a grey background and turquoise boxes and
whiskers. I cannot figure out how to just get black and white to be
the default. Can anyone help me with this?
Thanks

Repeated measures regression
Hi List,
Just wondering if there is such a thing as repeated measures
regression, and if so, can R do it?
I have repeated measurements of 10 individuals over a 45 day period,
and I would like to regress their daily activity time against a daily
environmental temperature. If I do so using averages of activity time I
find a significant negative correlation, but I worry that because I
have

Barchart to make a graph like this??
Hi list,
I'm trying to get R to make a graph like the one shown in this pdf, where
males are white bars and females are black bars.
http://www.brrc.unr.edu/~knussear/mmgraph.pdf
I tried barchart, but I couldnt get the bars to share a common x axis.
Do you have any suggestions?
Thanks for your help

Function to Sort and test AIC for mixed model lme?
Hi List
I'm running a series of mixed models using lme, and I wonder if there
is a way to sort them by AIC prior to testing using anova
(lme1,lme2,lme3,....lme7) other than by hand.
My current output looks like this.
anova
(lme.T97NULL.ml,lme.T97FULL.ml,lme.T97NOINT.ml,lme.T972way.ml,lme.T97fc.

how to suppress whiskers in a bwplot?
dear R-help,
i have looked carefully through the R-help archives for information on how
to suppress whiskers in a bwplot. someone asked this question a while
ago, but the answer he received is not available in the archives.
but i did manage to get my hands on a panel function (called
"my.panel") that is supposed to do this (the function is reproduced at the
end of the email, below).

Problem with bwplot
Try factor(vec2) in your bwplot() call.

xy plot key colors don't match plot
Hi
Trying to finish a simple xyplot, but the key colors don't match
those specified on the plot. I have only been able to change the
color of the key text, but not the points.

bwplot change whiskers position to percentile 5 and P95
Dear R-community,
Using bwplot, how can I put the whiskers at percentile 5 and percentile 95,
in place of the default position coef=1.5??
Using panel=panel.bwstrip, whiskerpos=0.05, from the package agsemisc gives
satisfaction, but changes the appearance of my boxplot and works with an old
version of R, what I don’t want, and I didn’t find the option in
box.umbrella parameters
Many thanks

Boxplot: quartiles/outliers
For boxplot(), is it possible to pass in a parameter to change the default
way that the 1st and 3rd quartiles are computed? (specifically, I'd like to
use type 6 described in the quantile function).
Also, what are the options for how outliers are computed, and how can one
change them?
Thank you

Lattice::bwplot unexpected behaviour when using vector of colors
Hi,
I'm trying to produce colored boxplots using lattice::bwplot function. I need to plot each boxplot in the panel with a specific color. Naturally I used a vector of colors and expected to see colored boxplots. Although the boxplots were colored, the color of whiskers and the boxes do not match. Here is an example:
d = data.frame(y = rnorm(100), x=1:4)

bwplot: how to display response variables separately in same panel?
Hi -
I have two response variables 'y1' and 'y2' and a factor 'x'. I would like
to create paired box-whiskers plots for y1~x and y2~x and labeled for the
same x. the b-w plots would be side-by-side in the same panel - almost like
a barchart with two parallel columns for the same x.
the code 'bwplot(y1+y2~x, outer=T)' gives me two side-by-side panels. this
is ok,

box and whisker (PR#13821)
In a Box and Whisker plot, I thought that when there are outliers both abov=
e and below the whiskers, then the whiskers should both be the same length =
(plus or minus 1.5 times the inter-quartile range).
If you look at the plot for SilwoodWeather on p.155 of The R Book you will =
see that for November (month =3D 11) the upper whisker is shorter than the =
lower, while for other months with

Whiskers on the default boxplot {graphics}
How are the lower/upper whiskers defined in the default version of boxplot {graphics}?
I tried help(boxplot) and searching www.rseek.org, but I was unable to determine an absolute answer.
I checked out the definition of boxplot according to Wikipedia (http://en.wikipedia.org/wiki/Box_plot), but it also had several approaches
listed for how the whiskers could be determined, so I'm just

boxplot statistics
I have read and reread the boxplot and the boxplot stats page, and I
still cannot understand how and what boxplot shows. I realize that
this might be due to me not knowing enough statistics, but anyway...
First, how does boxplot determine the size of the box? And is the line
inside the box the mean or the median (or something completely
different?) And how does it determine how long out the

boxplot $conf
Hello R-Help,
Could anybody tell me how the boxplot-function calculates the upper
and
lower extremes of the notch contained in $conf which I assume is the
confidence interval? Is it reliable for data which is not normally
distributed? If not, how can I calculate and boxplot a specific
confidence interval for not normally distributed data in R (increasing

help understanding box plots
Another naive stats question. I'm trying to better understand what
boxplots are telling me.
I think what I see is the median and the boundaries of the 1st and 3rd
quartiles. The whiskers represent the range of the data unless there
are points which are outside "range" (default: 1.5) times the distance
from the median to that quartile. Is that right? I've read the

Boxplot not doing what I think it should
My box plot below is drawing its upper whisker all the way to the last point, instead of showing the point as an outlier. Am I misunderstanding, or is it a bug?
Help(boxplot) states for the parameter ?range? that ?this determines how far the plot whiskers extend out from the box. If range is positive, the whiskers extend to the most extreme data point which is no more than range times the

bwplot panels like stripplot
I would like to plot horizontal box-and-whisker plots in lattice where
each
factor has its own panel and scales are "free." Below is a stripplot
version
of what I have in mind. Substituting "bwplot" doesn't work. I know
it's gotta
be simple but I can't find the way . . .
