pairs, par
Hi,
I posted over at R-help, and didn't get a response, but perhaps that
was the wrong forum for this question. I'm having some confusion over
the coordinate system after using pairs. I'm not interested in the
content of the actual pairs plot, although the number of pairs seems
to matter a bit. I'm purely interested in knowing where subsequent
points will be plotted on the

mulitmodal distributions
Hello,
I see that "mclust" is a pacakge that handles fitting mixtures of normals.
Are there any other packages out that that can handle mixtures of gammas or
other exponentials?
Additionally, are there any packages out there that can fit bimodal
distributions without mixtures? i.e., Cobb et al. 1983 using moment
recursion relations?
Thank you!

try FlexMix RE: mulitmodal distributions
Hi, Marion,
I believe the package FlexMix provides a more generalized version of
finite mixture modeling than is found in mclust/mclust02.

Replicating Rows
Hi,
I have a data matrix in which there are 1000 rows by 30 columns. The first
column of each row is a numeric indicating the number of trips taken to a
particular location with location attributes in the following column entries for
that row.
I want to repeat each row based on the number of trips taken (as indicated by
the number in the first column)...i.e., if 1,1 indicates 4 trips, I want

Convergence problem with zeroinfl() and hurdle() when interaction term added
Hello,
I have a data frame with 1425 observations, 539 of which are zeros. I
am trying to fit the following ZINB:
f3<-formula(Nbr_Abs~ Zone * Year + Source)
ZINB2<-zeroinfl(f3, dist="negbin", link= "logit", data=TheData,

par
Dear all, I have a question about "par" options.
When I choose par(pty="s",mfrow=c(2,2)), how can I change the horizontal distance between
the plots????
I have tried to use some options, like "mai", "mar", "oma", "omd", so on but I didn''t get the expected result.
Some suggest will be appreciated.

NUT UPS in check_mk (OMD) monitoring - does a parser script already exist?
Hello,
When I issue upsdrvctl status I see a NUT version 2.6.4.
I've installed NUT via apt-get install nut-server on the my Raspberry Pi
running Debian Jessie.
I've been looking at different monitoring systems to use. I really like
the look of Open Monitoring Distribution (OMD). OMD bundles Nagios
together with many addons including check_mk. I've installed the check_mk

pulling recessions out of a hydrograph
Dear R community,
I'm hoping someone out there has perhaps done this and can share their code
and/or expertise with me.
I need to pull recession periods out of a hydrograph - can anyone help me
with this?
I want to create a subset from streamflow data that consists of just the
recession curves - the decreasing runoff after the passage of a peak flow.

question concerning par("plt") and par("mar")
Hello,
I have a function that changes par("plt") to plot a colorkey, and upon returning resets the original value.
Unfortunately this changes the size of the plots when I change the layout. A simplified example:
par(mfrow = c(1, 1))
plt <- par("plt")
# .... # change par(plt) and create colorkey
par(plt = plt) # resets the default

advice on writing/maintaining an R package with a version control system
Dear all,
As I resume my dissertation work next month, I'd like to actually
start an R package this time around. I haven't done so because I
update my code very often (still in development phase), so running the
skeleton function, running checks, building, and re-installing the
package onto the system seemed like a long and tedious process.
I would like to hear your experience on how

Clipping using par(plt=..., xpd=FALSE) inconsistencies
Here is a demonstration of behaviour that is probably an optimization by
someone far smarter than me that did not anticipate anyone wanting to do
this, but for my purposes it looks more like a bug than a feature.
I have tested this with R2.6.2 on Windows, no additional packages loaded
(beyond the default), I have tested using the default graphics object,

2.7.0 graphics changes and png devices
Hi,
I have a question about the graphics changes in 2.7.0. The example is
this bit of code:
par(mfcol = c(2, 3))
for(i in 1:6) plot(1:10, 1:10, xlab = "xlab", ylab = "ylab", main = "main")
In 2.7.0, if I do this interactively (using windows()), I get bold
titles. If I do this through a png device, I get regular weight
titles. If I do this in 2.6.2, both

compositional time series
Dear R users,
i am wondering if anyone has some hints for this problem (i have not found a clear answer after searching the R-mailing list archive, 'help.search' in R, and R-Wiki, and the like...):
let's assume that i have 4 periods compositional time series data:
t=1, A=0.1; B=0.5; C=0.4
t=2, A=0.2; B=0.4; C=0.4
t=3, A=0.5; B=0.3; C=0.2
t=4, A=0.4; B=0.3;

altering a global variable
I'm working on a program that loads several large data files. I'm
using ddply (plyr is really awesome) but I want to minimize the amount
of times a large data file is read in. One solution is to keep track
of which data file is open with a global variable and then change the
currently open data file globally as needed. However, I'm unclear on
how to alter a global variable

R 2.11, shell, spaces
Can somebody confirm some unexpected behavior? This is under Windows,
with R 2.11.0 and 2.11.1.
1. Create a trivial test file (I called it test.R) containing:
cat("Success.\n")
2. Load R (Gui or Term) and run:

In my case, I get various error messages. If the

Windows installer, HTML help, R 2.10.0
I'm not 100% sure this hasn't been covered already (I searched a bit,
but I had a little trouble filtering down to a useful number of useful
results). Anyway, when I install R on Windows, the installer asks to
set the default help type. For some reason, I can set it as HTML in
the installer, but the results open as if help_type = "text" by
default. I presume this is related to

suppress printing within a function
I'm working with a few functions (e.g. do.base.descriptions in the
netstat package) that, in addition to returning an object with
variables I want to extract, also print output. There is no way to
turn this default printing behavior off in many of the functions.
Is there a blanket way to suppress such printing, say, within a loop
or a ddply statement?
Thanks!

illustration of graphics terms in R?
Hello,
I'm using R to do survey analysis and plotting. I've gotten good help on this
list to sort out specific plotting issues, but I think I could do a lot more
on my own if I could find a good reference that explained some of the graphics
terms and concepts used by R. I haven't found a general discussion of the
graphics environment, with illustrations. Part of my problem is that the
