In this case, if the requirement was Distances == 0.2

"continuous" boxplot?
...0 to 1, so I?d like
to plot the median and quantiles, and possibly also all of the
outliers somehow. Are there any facilities in R for doing something
like this, or would I need to do this the hard coded way?
Thankyou very much for your help!

multifigure question
...V1 and c$V1 in separate plots simply using
plot(), how do I put them next to each other?
I am sorry if this is a FAQ, but I cannot understand what
it says in the guide and the wonderful google couldn't
turn up anything helpful either...:)

graphics guide?
...)
before every new plot command, I have however not found any
explanation of what this actually does. ?plot.new does give an
explanation, but it is explained in R, so to speak. Where do I find
out what for instance a graphics frame is?
Thanks,

combine vector and data frame on field?
...called PID in the data frame.
Any hints on how to do this? cbind just adds the vector onto the end,
and I couldn't quite figure out if I could somehow say that the level
should correspond to the PID.
Thanks a lot for your helpin advance:)

multi-class histogram?

the size of each coloured area represents the proportions of the values
in that column that comes from each of the three classes. Do you have
any tips on how I do this?

boxplot statistics
...should
go?
Also, the boxplot.stats page talks about "hinges", what are those?
"The two "hinges" are versions of the first and third quartile, i.e.,
close to 'quantile(x, c(1,3)/4)'."
Thankyou very much.

function on factors - how best to proceed
...proceed. Should I deconstruct the data frame
within the function, or should I get just the numbers out of the
factors and input that into the function? Or is my solution way off
from how things are done in R?
Thankyou very much for your help!

cloud plot has white(transparent?) background
...on the webpage this comes out with a nice gray
background that makes things easier to see. Mine comes out with a
white, potentially transparent background and also the point colors
have changed.
How do I get the nice gray color back?
Thanks!

extracting p-values from the Manova function (car library)

i am not able to extract the p-values from the
Manova function in the car library. I need
to use this function in a high-throughput setting
and somehow need the p-values produced.
Any ideas?

creating summary functions for data frame

I realize that this is probably pretty easy to do, but I do not know
