Boxplot issues
Boxplot and bxp seem to have changed behaviour a bit of late (R 2.4.1). Or maybe I am mis-remembering.
An annoying feature is that while at=3:6 will work, there is no way of overriding the default xlim of 0.5 to n+0.5. That prevents plotting boxes on, for example, interval scales - a useful thing to do at times. I really can see no good reason for bxp to hard-core the xlim=c(0.5, n+0.5) in the

boxplot and bxp do not respect xlim by default (PR#9754)
Full_Name: Steve Ellison
Version: 2.4.1
OS: Windows, Linux
Submission from: (NULL) (194.73.101.157)
bxp() allows specifcation of box locations with at=, but neither adjusts xlim=
to fit at nor does it respect xlim provided explicitly.
This is because bxp() now includes explicit xlim as c(0.5, n+0.5), without
checking for explicitly supplied xlim (or ylim if horizontal).
This also prevents

boxplot question
Hi All,
As a follow-on from the mail below, it is possible to have boxplots based on
means and variance for more than one input, i.e.,
bxp(input1,input2,....)
Thanks in Advance,
Dermot

extending boxplot with space() argument?
A student asked me if it was possible to draw boxplots where the boxes
themselves were grouped: I was able to hack boxplot.formula() to do the
right thing, more or less, by incorporating an argument (space) and some
code from barplot.
with the extended boxplot.formula() below, the following commands "do the
right thing" (produce boxes grouped by levels of the second factor):

Quasi-bug in boxplot().
There seems to be a problem with partial matching of argument names
in boxplot(), in respect of the "horizontal" argument. I don't
recall seeing this issue discussed previously. My apologies if I am
being redundant. (A scan of CRAN revealed that someone had
experienced problems with the "horizontal" argument, but he was
spelling it out in full, so that was a different

Feature request: add boxplot()s to current plot (given x[i])
(as the subject says)
It makes sense to add (say k) boxplots to a given plot,
using the given coordinate system.
Currently, the calling sequence
boxplot -> boxplot.default() -> bxp()
[modeled after S]
doesn't allow this, since bxp() explicitly
sets up the coordinate system.
One way would be to add an "add = TRUE" argument to boxplot(.) and bxp(.)
and then additionally

Expressions from boxplot() passed to bxp()
It's not new anyway. You see the same behaviour with
boxplot(dat, ylab=quote(X[2]))
and it boils down to the use of do.call("bxp", ...) in the internals.
As a general matter, expression() exists to prevent this sort of confusion, e.g., in this construction,
> X <- quote(Y+1); bquote(f(.(X)))
f(Y + 1)
is indistinguishable from just entering f(Y+1), so f has no way of

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

cex.axis in boxplot (PR#2628)
Hi,
the graphical parameter "cex.axis" does not have any affect for "boxplot":
data(iris)
boxplot(iris[,1:4], ylab="y", cex.lab=2, cex.axis=2)
The patch is simply adding "cex.axis" to the search for axis relevant
parameters in "bxp":

Small inconsistency with boxplot
Dear R-core team,
I think I found a small inconsistency in the boxplot function. I don't want to post it as a bug since I'm not sure this might be considered as one according to the FAQ --- and this is not a major problem. Don't hesitate to tell me if I'm wrong.

Superposing data on boxplot
Hi folks,
I have a vaiable Y and an associated factor Z at several (13)
levels.
boxplot(Y~Z)
produces a nice array of boxplots, one for each level of Z,
and each duly labaelled with its level of Z.
I would like to superpose on each boxplot the actual data
points which it represents, i.e. do something conceptually
(though not in real R) expressed as
points(Y~Z)
or
points(Z,Y)

Unexpected behavior in boxplot
When plotting using the cex.axis argument to boxplot(), the size of the
plotting symbols beyond the whiskers of the boxplot are being changes.
Example:
par(mfrow=c(2,1))
boxplot(c(rnorm(10), 10), horizontal=TRUE, main="Test", las=2, cex.axis=2)
boxplot(c(rnorm(10), 10), horizontal=TRUE, main="Test", las=2, cex.axis=1)
