ordered boxplots
Dear List-Members,
I would like to produce a ordered boxplot in which the categories with
the smallest median are plotted at the left end and the box with the
largest median at the right.
Thanks in advance for any advices

displaying sample size in boxplots
Hi,
I was wondering if there is a ready made function or parameter
for indicating the sample size in boxplots?
Here's what I came up with so far:
library(ISwR)
data(energy)
attach(energy)
boxplot(expend~stature)
sample.size <- tapply(expend, stature, length)
sample.size <- paste("N=", sample.size, sep="")
mtext(sample.size, at=1:length(unique(stature)), line=2,

boxplot() confuses x- and y-axes (PR#10345)
Full_Name: Bob O'Hara
Version: 2.6.0
OS: Windows XP
Submission from: (NULL) (88.112.20.250)
Using horizontal=TRUE with boxplot() confuses it as to what is an x- or y-axis.
At least, xlim= and ylim= are the wrong way round, log="x" (or "y") and xaxt=
work as expected, I haven't looked at anything else.
Some code to see if you can reproduce the bug (or discover

How to get a grid behind a boxplot
I am using R 2.2.1 on a Windows 2000 PC.
When I do a grid() after the boxplot
it overprints the boxplot:
> boxplot(count ~ spray, data = InsectSprays, col = "lightgray")
> grid(nx=NA, ny=NULL)
>
if I try the panel.first
> boxplot(count ~ spray, data = InsectSprays, col = "lightgray",
+ panel.first=grid(nx=NA, ny=NULL))
>
I can see the grid flash

Como marcar la media en un grafico boxplot ??
Estimados amigos, mi pregunta es bien directa, a ver si alguien me puede
ayudar:
Como marcar la media en un grafico boxplot ??
Por lo que veo, los boxplot en R marcan por defecto la mediana dentro de la
caja, pero necesito marcar la media y ojala sacar la mediana para que no
aparezcan los dos parametros.
Por lo que he leido, imagino que se puede hacer con alguna funcion de bajo

Ordering boxplot factors
Hi all,
what a great help list! I hope someone can help me with this puzzle...
I'm trying to find a simple way to do:
boxplot(obs~factor)
so that the factors are ordered left-to-right along the x-axis by
median, not alphabetically by factor name.
Complicated ways abound, but I'm hoping for a magical one-liner that'll
do the trick.
Any suggestions would be treasured.
Thanks,

ordering boxplots according to median
Dear R-users,
Does anyone knows how I can order my serie of boxplots from lowest to
highest median (which is much better for visualization purposes).
thanks in advance,

Problems with par() and labels with boxplot
Quite a simple one really!
When I run boxplot(), the labels on the X axis are horizontal, and I
want them vertical. So I did:
par(las=3)
boxplot(...)
And my labels just aren't there anymore....
Any help???

Stripchart and Boxplots side-by-side
Dear all -
With the following code I get Boxplots and Stripcharts in one Plot:
with(InsectSprays, boxplot(count ~ spray, boxwex = 0.3))
with(InsectSprays, stripchart(count ~ spray, col = "red", vertical =
TRUE, add = TRUE))
But the dots from the stripchart are plotted over the Boxes.
Is there any possibility to have Stripchart and Boxplots side-by-side,
i.e. to move boxplots and/or

A question about boxplot: mean and median
Dear List,
I have worked through the examples given in the help
on boxplot(). If I am reading it right, only the
median is produced (as a default), which is
represented by the horizontal line inside the box.
What argument do I need to specify if I want to show
the mean as well?
Thanks,

xfig boxplot (polygon) bug??
There appears to be a bug in the R xfig() driver.

the boxplot is fine. Doing the same thing after

and then opening in Xfig (ver3.2 patchlevel 2) on my Linux box produces boxplots

Sorting problem
Hi
I'm using R 2.0 in SuSE 9.2.
When I plot data as a boxplot, the boxes appear on the plot in
alphabetical order (of group) rather than the order in which they appear
in the data. So far, the only thing I can do to fix this is to prefix
the group labels with a,b,c...etc to trick R into plotting them in the
right order.
Can sorting be turned off?
How should I address this sensibly?
Thanks

overlap dot plots with box plots
Hi,
I am new in R and would like to dot plot my real data points from different
categories and put box plot overlapping. To give a feeling of the
distribution of my data and the real values.
I managed to that in excel but it takes a lot of time and it makes the
program crash quite often!

how to change the thickness of the lines of the boxplot outliers
Hi,
I tried to use boxplot function. I am following the ?boxplot and can
change the whisker box width using lwd parameter. However, when
outline=TRUE, the thickness of the circle of the outliers is not
proportionally changed when I change the line width of the whisker
box. There must be another parameter for that. Unfortunately I don't
know.
please help and thanks much in advance.
