Vioplot / list help
Hi,
I have some data (lots of year,distance pairs), which I can
straightforwardly boxplot:
dists <- read.table("movedists.dat")
with(dists,plot(as.factor(V1),V2))
If I want to plot these data as violin plots using vioplot, this
approach doesn't work:
> with(dists,vioplot(as.factor(V1),V2))
Error in Summary.factor(c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, :

colour-plot of point intensities?
Hi,
I've spent a while scrabbling around at this problem, to no avail. I'm
sure there /should/ be a simple answer...
I have a large (14 million rows) data set, with two columns. Each row
contains the number of times an individual moved, and the distance
that individual moved in total. I would like a figure where the colour
indicates the density of points, rather like this one my

Boxplots using percentiles?
The standard R boxplot appears to use quartiles to determine the height of
the rectangles and a range parameter - RNG - (default=1.5 I think) that
determines the length of the whiskers as <= RNG x Interquartile Range. Is
it possible to instead define the range as extending to the 95th percentile?
If so, how would this be done?
nb, I'm plotting multiple boxplots on a single chart so a

Removing lower whisker in boxplot to see the effects of the high values
Good Afternoon-
I was wanting to alter the boxplot to remove the lower whisker, both the
whisker line and staple just on the lower end. Is there a way to do this?
As my code is currently:
boxplot(log_loads~ind,data=nfmaum, horizontal=TRUE, notch=T, outline=FALSE,
whisker=0, main="Maumee River Near Future Climate Scenarios", ylab="Log
Load",xlab="Climate Scenarios")

mild and extreme outliers in boxplot
dear all,
could somebody tell me how I can plot mild outliers as a circle(?) and
extreme outliers as an asterisk(*) in a box-whisker plot?
Thanks very much in advance

boxplot knowing Q1, Q3, median, upper and lower whisker value
Dear list,
I am using a external program that outputs Q1, Q3, median, upper and lower whisker values for various datasets simultaneously in a tab delimited format. After importing this text file into R, I would like to plot a boxplot using these given values and not the original series of data points, i.e. not using something like boxplot(mydata).
Is there an easy way for doing this? If I am not

about the whisker in boxplot
Hi, Dear R-users,
I have a problem when I drawing a boxplot. I want to extend the whisker to
the 5% and the 95% quantiles and only show the most extreme outlier, like
0.01% and 99.99% percentiles. What should I do?
I saw something on boxplot.stat, but even I define the parameter in
boxplot.stat, what I should do next? how to connect it to boxplot?
Thank you very much!

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

custom graphing of box and whisker plots
Hi,
I'm trying to graph some data in a boxplot-like style, but I want to set
the box and whisker limits myself (rather than having R calculate them for
me). I'd like the boxes to be shaded and the whiskers to be dotted lines.
My data are set up is something like this:
min.whisker max.whisker min.box max.box species

changing parameters of the box and whisker plot
Hello:
I am plotting some data using the box and whisker plot. However, I only want to plot the median, max and min, as I only have these values and not the quartile values. It seems R arbitrarily constructs the box margins to be halfway between the median and the max/min. How do I make the box and whisker plots without the box values?
Thanks,
Michael

Great looking plot - but what does it mean?

Hi,
R is is world full of wonders... I created the attached plot, and I think
it's exactly what I need! Well, actually I think it is more that wht I
need...
I wanted R to show the mean values of the categories on the x-axis and maybe
the standard derivation as well.
I am pretty confident that the bold horrizontal lines in the plot show

argument handling in boot.ci
Hi,
boot.ci fails to check if the "type" argument is valid or not. This
tripped me up when I had a script that called boot.ci(type="normal",...)
repeatedly - only later when I tried to do some further analysis did I
realise I'd got nothing useful back from boot.ci.
It strikes me that this behaviour is probably incorrect, and that
boot.ci should stop if the

sample weight for box plot?
Hi,
I would like to make a box and whisker plot but use a sample weight for each
observation. I've searched around a bit and have not found a method of
doing this.
Anyone have any advice?
Thanks much,
Sean Parks

Custom Plot - means, SD & 5th-95th% (Plotmeans or Boxplot)?
Any help with this problem would be greatly appreciated:
I need to produce a custom plot i haven't come across in R. Basically, I
want to show means, 1st standard deviation and 5th and 95th percentiles
visually, using something resembling a boxplot. Is it possible to completely
customize a boxplot so that it shows means as the bar (instead of, not as
well as medians), standard deviations at

what does boxplot draw?
Dear r-help,
Unfortunately I cannot find in the documentation what determines
ranges of a 'box' in the box-and-whisker plot.
It is said in "Simple R" (http://www.math.csi.cuny.edu/Statistics/R/simpleR)
that they are 1st and 3rd Qus usually.
I tried to add to boxplot lines with (quantile(x,probs=0.25)), but
lines do not coincide with edges of boxes.

Dividing a vector into ntiles
R 2.1.1
Win 2k
Would someone suggest a method (or methods) that can be used to
determine ntile cutpoints of a vector, i.e. to determine values that can
be used to divide a vector into thirds such as 0-33 centile, 34-66
centile, 67-100 centile. If for example I had a vector:
1,2,3,4,5,6,7,8,9
and wanted to divide the vector into thirds
I would have cut-points of 3, and 6.
Thanks,

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

Boxplot in R
I am trying to draw a plot like Matlab does:
The upper extreme whisker represents 95% of the data;
The upper hinge represents 75% of the data;
The median represents 50% of the data;
The lower hinge represents 25% of the data;
The lower extreme whisker represents 5% of the data.
It looks like:

Box plot with 5th and 95th percentiles instead of 1.5 * IQR: problems implementing an existing solution...
Hi all,
I'm just getting started with R and I would appreciate some help. I'm having
trouble creating a boxplot with whiskers at the 95th and 5th percentiles
instead of at 1.5 * IQR. I have read the relevant documentation, and checked
existing mails on this topic. I found a small modification that should work

boxplot graphical arguments (PR#6832)
Dear r-bugs,
I'd like to be able to draw boxplots with solid or dotted whisker lines.
The lty argument is currently ignored by boxplot(), and indeed hardwired
in bxp().
It's not very difficult to customize these functions to generate various
types of boxplots, but generally it might be an idea to allow the user to
pass a few more graphical arguments to boxplot(). The approach might as
