database-like natural join operations in R?
I am a relative neophyte to R and am faced with a problem of
constructing a reduced data set from a diversity of separate sources.
What operations are available in R for combining and matching
attributes from separate data.frames?
Thanks for any pointers/guidance!

how to change the history size in R
I would like to make readline's command history in R-0.63.1
substantially larger than it is by default (seems like around only 50
commands). How do I change the size?
Thanks!

"normal probability plot" with a percentile scale?
I'd like to generate some plots like you'd see on the old "normal
probability graph paper", like the first plot in:
<http://www.itl.nist.gov/div898/handbook/eda/section3/normprpl.htm>
except the horizontal scale would have 1%, 5%, 25%, 50%, 75%, 95%,
99%, or similar quantiles, with associated tick/grid lines. [still
hunting around for a good example...] something like

Wishlist items
I''ve been saving up a few wishlist items for zfs. Time to share.
1. A verbose (-v) option to the zfs commandline.
In particular zfs sometimes takes a while to return from zfs snapshot -r
tank/volumes at foo in the case where there are a great many iscsi shared
volumes underneath. A little progress feedback would go a long way. In
general I feel the zfs tools lack sufficient feedback

cross-platform code: windows or gnu/linux?
I am writing some R code that generates some figures. I am primarily
developing on GNU/Linux, but will ultimately run the code on Windows
in order to get WMF files I can integrate in an existing document.
The win.metafile() function, of course, doesn't exist in the GNU/Linux
version of R. I am contemplating writing an abstraction layer that
runs the right thing, but I need to know how the

coercing "numeric" components of data frame to "factor" or "ordered"?
I am getting ready to load a bunch of data into R. The data is all
numeric, but some of the numbers are integer codes representing
non-numeric semantics. What is the best way to "fix" the data frames
so that these compenents are recognized as "factors" or "ordered", as
appropriate?
Can I "assign" to some attribute of the data frame component, like the

Teleport 1.0.1
I just released the Teleport gem - easy Ubuntu server setup via
teleportation. Teleport sets up servers by "teleporting" to the machine
and running itself there. It installs Ruby, then follows the
instructions laid out in your Telfile to customize the server.
https://github.com/rglabs/teleport
The role/server setup is similar to Capistrano, though the syntax is
slightly different. You

formula parsing, using parts ...
I am writing a little abstraction for a series of tests. For example,
I am running an anova and kruskal.test on a one-factor model. That
isn't a particular problem, I have an interface like:
my.function <- function(model,data) {
print(deparse(substitute(data)))
a <- anova(lm(formula,data))
print(a)
if(a$"Pr(>F)"[1] < 0.05) {

qqnorm() with weighted data?
I've got a set of data that are weighted by a largish integer (ranging
from about 50K to 1.5 million). I'd like to plot CDF's for this data
taking into account the weighting. What do you recommend?
Thanks!

why not link devices with --link-dest option?
I notice that devices are not hardlinked when using the --link-dest
option, for instance:
rsync -aH --link-dest=../bar/ foo/ baz/
When foo/zero is a device, baz/zero is not a hardlink to bar/zero. How
come?

estimating quantiles from binned data
Suppose I have a set of binned data, counts exceeding a series of
arbitrary thresholds, a total N, a minimum and maximum, those sorts of
things. Is there a "standard" method for estimating arbitrary
quantiles from this?
My initial thought is that the counts and min/max give me solutions at
various points along the empirical cdf. As the data are roughly
log-normal, I thought maybe I

random uniform sample of points on an ellipsoid (e.g. WGS84)
I am interested in making a random sample from a uniform distribution
of points over the surface of the earth, using the WGS84 ellipsoid as
a model for the earth. I know how to do this for a sphere, but would
like to do better. I can supply random numbers, want latitude
longitude pairs out.
Can anyone point me at a solution? Thanks very much.

variance component analysis for nested model
Given a set of data:

I am looking for a way to compute the variance components of the
nested model (ie, visit 1 at house 2 at city 3 isn't related to visit
1 and house 2 at city 4), but different houses in the same city may be
related, and different visits to the same house are probably

rsync --dry-run --link-dest problem
I am trying to use rsync for making snapshots, sharing hardlinks at
the destination using the --link-dest option. In conjunction with
this, I would like for --dry-run to report some reliable-ish number
for how much space it is going to consume at the destination so that I
can arrange to free such space prior the launching rsync "for effect".
Right now, that isn't working:

solving for a 2D transformation matrix
We have recently digitized a set of points from some scanned
engineering drawings (in the form of PDFs). The digitization resulted
in x,y page coordinates for each point. The scans were not aligned
perfectly so there is a small rotation, and furthermore each
projection (e.g. the yz-plane) on the drawing has a different offset
from the page origin to the projection origin. From the dimensions

good procedure for creating plots for PowerPoint
I am generating some graphs (on GNU/Linux using R 1.5.x) for a
PowerPoint presentation my boss is giving next week. He just tried
cut/pasted a plot off of a PDF file I had created, but he complained
that the fonts were too small and fuzzy, and that he couldn't change
the background. I have been playing with png(bg=transparent), but I

Spearman rank-order correlation matrix

rank-order correlation matrix from without disturbing the original

using gkermit with ssh (wishlist item)
I've been toying with the idea of using gkermit
over an ssh connection. As it stands, gkermit is essentially
featureless, a GPL kermit implementation that's enough to
get the Free software advocated off their backs. However,
since they want to continue to sell C-Kermit, it has all
the `useful' features, such as scripting, but more importantly
the ability to create a connection over
