R process must die - can I save history?
I connected from my desktop Linux box to a Linux server using ssh in an
xterm, but that xterm was running in Xvnc. I'm running R on the server in
that xterm (over ssh). Something went wrong with Xvnc that has caused it
to hang, probably this bug:
https://bugs.launchpad.net/ubuntu/+source/vnc4/+bug/819473
So I can't get back to that ssh session or to R. I had done a bunch of

R package that has (much) the same capabilities as SAS v9 PROC GENMOD
I need capabilities, for my data analysis, like the Pinheiro & Bates
S-Plus/R package nlme() but with binomial family and logit link.
I need multiple crossed, possibly interacting fixed effects (age cohort of
twin when entered study, sex of twin, sampling method used to acquire twin
pair, and twin zygosity), a couple of random effects other than the cluster
variable, and the ability to

determining the order in which points are plotted
I make plenty of scatterplots, especially using scatterplot.matrix from
library(car). One thing I don't know how to do is determine which points
are plotted last. Sometimes I plot a large number of points for multiple
groups represented by different colors.
I would like to guarantee that point that are far from the centroid for
their group are plotted last. This way they will be

UNIX-like "cut" command in R
The R "cut" command is entirely different from the UNIX "cut" command.
The latter retains selected fields in a line of text. I can do that kind
of manipulation using sub() or gsub(), but it is tedious. I assume there
is an R function that will do this, but I don't know its name. Can you
tell me?
I'm also guessing that there is a web page somewhere that will tell

storage and single-precision
I'm getting the impression from on-line docs that R cannot work with
single-precision floating-point numbers, but that it has a pseudo-mode for
single precision for communication with external programs.
I don't mind that R is using doubles internally, but what about storage?
If all I need to store is single-precision (32-bit), can I do that? When
it is read back into R it can be

integer and floating-point storage
I note that "current implementations of R use 32-bit integers for integer
vectors," but I am working with large arrays that contain integers from 0
to 3, so they could be stored as unsigned 8-bit integers. Can R do this?
(FYI -- This is for storing minor-allele counts for genetic studies.
There are 0, 1 or 2 minor alleles and 3 would represent missing.)
It is theoretically possible

If find x, then y, else do nothing
I want to write code that says "If you find an element equal to 4 in this
vector for each person in the data set tested separately, then put in 1 for
2 and 2 for 4, else leave the variable as is"
u.ppl <- (unique(init.dat1$grid))

Counting Elements Conditionally
R -
I have 3 variables with data below. Variable "Rev" is a vector that changes
from 1 to 2, 2 to 3, etc.... Variable "FF" is a binary variable with 1's
and 0's. Variable "bin" is a different binary variable with 1's and 0's.
I want to calculate the number of elements:
1. Starting with the first element where Rev switches (i.e. 1 to 2)

bootstrap confidence intervals with previously existing bootstrap sample
Dear R users,
I am new to R. I would like to calculate bootstrap confidence intervals
using the BCa method for a parameter of interest. My situation is this: I
already have a set of 1000 bootstrap replicates created from my original
data set. I have already calculated the statistic of interest for each
bootstrap replicate, and have also calculated the mean for this statistic

Hidden Markov Models in R
R Community -
I am attempting to fit a model as described in Hampton, Bossaerts, and
O'doherty (J. Neuroscience) 2006. They use a bayesian hidden markov model
to model the Reversal Learning data. I have tried using HMM and depmixS4
with no success. My data is a Reversal Learning Task in which there are 3
sets of patterns over 3 blocks. The participant receives incorrect or

First Rails project: input welcomed
Hi everyone,
I''m working on my first Rails project and I''d like some input before
I get started coding in earnest. My previous Web app development
experience has been in standard Python CGI and Zope. I''m here to find

Exclude data using logical
Hi,
I'm wanting to exclude data more than 2 sd's from the mean before proceeding
with further analyses. I've created new logical variables (a and b) and
written them to the existing dataframe. I want to be able to subset the TRUE
observations based on another 2 factor variable. I'm assuming this is
possible, but I don't know what I'm doing wrong, as I get results that

[PATCH v2 0/4] Support drop directories directly from kinit
This patchset applies to klibc mainline.
This patchset introduces the ability to kinit to execute scripts or
executable files present in in the initramfs before switching over to
the root filesystem.
It is implemented by first implementing scandir() and alphasort() as
present in POSIX.1-2008 in klibc itself, and then using that as the
basis for iterating and executing files via a run_scripts()

lme object manipulation
Hello:
I have an lme object, say lme_res2, which was generated using the varIdent. I'm trying to extract the double 1.532940 from the object, but I can't find it by attributes(lme_res2) or attributes(summary(lme_res2)). How can I pull it out (so that I can save it to another variable)? Thanks.

For an analysis of data from twins, I'd like to do some rearranging in my

several columns of the co-twin's data to each row. In other words, this is
