"digits" in round()
Hi Folks,
Compare
print(1234567890,digits=4)
# [1] 1.235e+09
print(1234567890,digits=5)
# [1] 1234567890
Granted that
digits: a non-null value for 'digits' specifies the minimum
number of significant digits to be printed in values.
how does R decide to switch from the "1.235e+09" (rounded to
4 digits, i.e. the minumum, in "e" notation) to

significant digits (PR#9682)
I came to report this same bug and found it already in the trash, but
I slightly disagree with that assessment. If it's not a bug, then
perhaps it's a feature request. Comments at the end.

problem with "unique" function
I have the joint distribution of three discrete random variables z1, z2 and
z3 which is captured by "z"
and "prob" as described below.
For example, the probability for z1=0.46667, z2=-1 and z3=-1 is 2.752e-13.
Also, the probability adds up to 1.
> head(z) z1 z2 z3
[1,] -0.46667 -1.0000 -1.0000
[2,] -0.33333 -0.9333 -0.9333
[3,] -0.20000 -0.8667 -0.8667

problem with "unique" function
Most likely, previous computations have ended up giving slightly different values of say 0.13333. A pragmatic way out is to round to, say, 5 digits before applying unique. In this particular case, it seems like all numbers are multiples of 1/30, so another idea could be to multiply by 30, round, and divide by 30.

CallerID/variable setting.
Hey, all. I'm trying to set my CID such that, internally, I see a
four-digit extension (which is also handy when checking VM), but
externally, I see the full 10-digit number. So I plugged these lines into
my extensions.conf:
exten => _XXXXXXX,1,GotoIf($[ ${CALLERIDNUM} != 1625]?4:2)
exten => _XXXXXXX,2,Set(CALLERIDNUM=6031234${CALLERIDNUM:1})

Subsetting within xyplot()
All,
I'm having problems w/ a simple attempt to subset an xyplot.
The first plot below is a plot of y versus x for certain values of a third
categorical variable z. Now I'd like to further restrict this to certain
values of variable y. Neither of the two attempts below work. Any
suggestions much appreciated. (note: I don't want to merely use ylim since

Replacing plot symbols w/ subject IDs in xyplot()
All,
How does one replace plot symbols with say subject IDs when using xyplot? Or
superimpose them next to plot symbols? I searched the archives under
various key words but haven't had much. Any suggestions or links much
appreciated. Sample code below.

png with ggplot on windows xp
Hi Group,
I posted this question on the ggplot list and was advised to try here
also. The code
below produces a plot as a png and pdf. The pdf looks great, and I cannot
make the png look this way. I've tried various combinations of
height, width, and dpi, but it has not worked out so
far. Any suggestions to make the png look like the pdf? I received a
response that

Echo cancel on HFC-S cards and CIDNum setting on outgoing calls
hi all!
I'm running an Asterisk-box with bristuff-....RC8n and 2 HFC-S cards.
I m located in Vienna/Austria. I have the problem that on outgoing
calls i hear my voice as a short echo (about half a second). This
occurs not on every call.
I tried some changes in my zapata.conf, with rxgain and txgain
settings, but to me its
hard to find a configuration which is good for every call i make. Is

Free space cache writeback issue

I''ve hit an issue with the free space cache. It looks like we miss writing

How to update an old unsupported package
Hi all,
I have a package that is specific to a task I was repetitively using a
few years ago.
I now needed to run it again with new data.
However I am told it was built with an older version or R and will not work.
How can I tweak the package so it will run on 11.1?
It was a one-off product and has not been maintained.
Is there a way to "unpackage" it and repackage it to work?

Formatting in formatC and format (PR#129)
[This turned into a bug report which will go to r-devel, so I have taken it
off r-help.]
Bugs reported here:
(1) formatC's help page need some clarification.
(2) formatC needs to treat modes "double" and "real" as equivalent.
(3) format's help page or (preferably) format needs correction re the
meaning of `digits'

(x,y) coordinates for grid.text()
All,
When using grid.text it seems my supplied (x,y) coordinates are being
plotted only in npc (normalized parent coordinates) where (.5,.5) is the
center of the graph. How do I allow (x,y) to be coordinates corresponding
to the (x,y) values in the graph? The examples in ?grid.text seem to do
this. (I think the problem lies in how x and y are defined with respect to
unit ). Any help much

help with aggregate(): tables of means for terms in an mlm
I'm trying to extend some work in the car and heplots packages
that requires getting a table of multivariate means for one
(or later, more) terms in an mlm object. I can do this for
concrete examples, using aggregate(), but can't figure out how to
generalize it. I want to return a result that has the factor-level
combinations as rownames, and the means as the body of the table

polychoric correlation error
Dear all,
I get a strange error when I find polychoric correlations with the ML method, which I have been able to reproduce using randomly-generated data.
What is wrong?
I realize that the data that I generated randomly is a bit strange, but it is the only way that I duplicate the error message.

Using R for Multiple Regression
Hi,
Subject: Using R for Multiple Regression
I am new to statistic but am interested in applying mathematical models to
solve biological problems. I have used a linear model to generate the test
data. When using this data I expect R to correctly identify the model but
that does not seem to be the case. I am certain that I am doing something
wrong but not able to figure it out.

apply'ing cut to a data.set column
Hi all,
there is probably something I'm still missing about how R
manipulates multivariate data. I have a dataset in which, for various
tuples of a set of 4 parameters, a value of interest is stored:
p1 p2 p3 p4 v

0 1 1 0 0.6124
