Problems getting Gravity to run
Hi,
I'm having difficulties getting the news reader, Gravity, running
reliably.
Gravity installed okay, and I ran it for a single session.
During that test, the following messages appeared many times:

spatial interaction (gravity) model as Poisson regression
Dear list,
I posted essentially this same question to the r-sig-geo mailing list
last week with no response :( Unfortunately I am no closer to reaching
a solution, so I now post it here (with some clarifications) in the
hope that someone following this list might have an answer for me:
Has anyone had much experience with spatial interaction (or gravity)
models, specifically in the form of

Building an R package under Windows NT
I am trying to build a R 1.7 package under Windows NT. I created the
DESCRIPTION file, the RD file and added the code to the R folder. I also
downloaded and installed the Rtools package and have Perl 5.0. I know that
Perl, Miktex, and gcc are working. I also have my PATH variable set
correctly. I can fake install my package by removing the *.R from the code
file, using Rcmd Rdconv to create

CLDAP using CPU alltime on Samba 4.8.4
Hi,
My Samba AD-DC installation is using CPU all time on a process. I'm trying
everything to fix it, but without success.
It started when using it on Ubuntu 16.04, I upgraded o Ubuntu 18.04, and
now Ubuntu 18.10, that is using Samba 4.8.4 and the problem persist.
Using samba-tool process, I could see that the process using resources is
CLDAP.
I did samba-tool dbcheck --cross-ncs

ipf function in R
Hi
I have a 3 x 2 contingency table:
10 20
30 40
50 60
I want to update the frequencies to new marginal totals:
100 130
40 80 110
I want to use the ipf (iterative proportional fitting) function which
is apparently in the cat package.
Can somebody please advice me how to input this data and invoke ipf in R
to obtain an updated contingency table?
Thanks.
By the way I am quite new to R.

Workflow to commit changes using git alone (?)
Hi All,
Ok, just for the matter of providing feedback that may be useful for others, I figured out one way to do it based on the setup that I described earlier. It can be something like this
git checkout patchbranch # checkout to the patch branch, this is the one containing the differential patch code
git checkout -b tmp # checkout to a new tmp branch
git reset —soft master

boot with strata: strata argument ignored?
Hello All. I must be missing the really obvious here:
mm <- function(d, i) median(d[i])
b1 <- boot(gravity$g, mm, R = 1000)
b1
b2 <- boot(gravity$g, mm, R = 1000, strata = gravity$series)
b2
Both b1 and b2 seem to have done (almost) the same thing, but it looks like
the strata argument in b2 has been ignored. However, str(b1) vs str(b2)
does show that the strata have been noted

problem with "which"
Hi,
I'm having trouble with the "which" or the "seq" function, I'm not sure.
Here's an example :
> lat=seq(1,2,by=0.1)
> lat
[1] 1.0 1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 2.0
> which(lat==1)
[1] 1
> which(lat==1.1)
[1] 2
> which(lat==1.2)
[1] 3
> which(lat==1.3)
[1] 4
> which(lat==1.4)
[1] 5
> which(lat==1.5)

Merging labels on Pie chart
Dear R Help Members,
I need to draw a pie chart for someone and there are 3 small slices in it identifying different species, all 0.7%, who’s labels overlap so you cannot read them. Is there a way to have only 1 label the three slices, so as to merge the three labels into one without merging the 3 slices? Alternatively, is there a way to extend the pointing lines, so that they could be different

gradient fill of a grid.polygon
Dear list,
Following a recent enquiry, I've been playing with the idea of creating a
colour gradient for a polygon, using the Grid package. The idea is to draw a
number of stripes of different colours, using the grid.clip function. Below
is my current attempt at this,
library(grid)
rotate.polygon <- function(g, angle=0){ # utility function, works fine
matR <- matrix(c(cos(angle),

Advice on approach to weighting survey
I'm about to add weights to a bus on-board survey dataset with ~150 variables and ~28,000 records. My intention is to weight (for each bus "run") by boarding stop and alighting stop. I've seen the Rake function of the Survey package, but it seems that converting to a "svydesign" might be excessive for my purpose.
My dataset has a huge number of unique

ESRI shapefiles and EMME/2 packages
I just uploaded two packages to CRAN.
shapefiles_0.1.tar.gz - functions to read and write ESRI shapefiles
(including dbfs)
emme2_0.1.tar.gz - functions to read binary data from an EMME/2 databank
data (EMME/2 is a transportation modeling program)
Please let me know if you find any bugs or have some suggestions. Thanks.

Build R-1.9.0 with static libraries ?
Dear all,
Which options should I use when running the configure script
and/or
which changes should I make to Makeconf
to build the binary for R-1.9.0 but using only statically linked libraries ?
I need to build a binary that is portable between several different
Linux (RedHat) distributions.
Thanks in advance for your help,

Re: [Nemo-devel] nuts status page
Adam: Thanks for putting up this page. But something is wrong. In
particular, our Powerware 9135 is a three phase UPS system with THREE 480
volt outputs. So the displayed voltage is not correct -- in fact there
should really be THREE voltages displayed, all around 480v.
Nut developers: I am copying the NUT mailing list to see if anyone can
suggest how to fix this. NUT developers, see the

Temporal Analysis of variable x; How to select the outlier threshold in R?
For a financial data set with large variance, I'm trying to find the
outlier threshold of one variable "x" over a two year period. I
qqplot(x2001, x2002) and found a normal distribution. The latter part of
the normal distribution did not look linear though. Is there a suitable
method in R to find the outlier threshold of this variable from 2001 and
2002 in R?

3D ellipsoid confidence region
I am curious if there is code developed to plot confidence regions in 3D.
The scatterplot3d function generates the plot I want, but would like an 3D
equivalent to the data.ellipse function.
Any help in this direction would be appreciated, be it theoretical,
graphical, or otherwise.

package is available?
Also, has anybody heard of a library called CarbamateData? [as in:

apache refuses to start because of port conflict
Here is the deal. I''m trying out the latest Instant Rails and when I
start it Apache claims that the web port is being used.
"Apache cannot be runned : another Web server use the Web port"
Okay, no problem. I went into the Apache configuration and changed the
port it was binding to. However I get the same problem.
The troubleshooting continues, so I install Apache by itself
