long character string problem
Hi All
I am having 2 very long character strings (550chars) and I want to put them as
expressions together with c(). The problem is that I also get these
double-quotes, as seen below in 'fct'. How can I remove these double-quotes? I
tried as.name() but it did not work (because of size?). These are creating
trouble with subsequent programs, which I tested with strings that for some

bootstrap confidence intervals, non iid
hello,
i need to calculate ci's for each of 4 groups within a dataset, to be able
to infere about differences in the variable "similarity". the problem is
that data within groups is dependent, as assigned by the blocking-factor
"site". my guess was to use a block bootstrap but samples within in these
blocks / sites are not of same length. i was not able to find a method to

glmer with non integer weights
hello,
i'd appreciate help with my glmer.
i have a dependent which is an index (MH.index) ranging from 0-1. this index
can also be considered as a propability. as i have a fixed factor (stage)
and a nested random factor (site) i tried to model with glmer. i read that
it's possible to use a quasibinomial distribution, for this kind of data,
which i than actually did - but firstly

contrasts for lmer model
hello,
i found it most convenient to use package contrast for planned comparisons
on mixed models.
for instance i have a model with 2 fixed factors, one with 4 levels (stage)
and one with 2 levels (gap) and a nested random factor (site) and i tested
gap within level A of factor stage:
library(contrast)
library(nlme)
m1<-lme(rich ~ stage*gap, random=~1|site,data=richness)

zero random effect sizes with binomial lmer [sorry, ignore previous]
I am fitting models to the responses to a questionnaire that has
seven yes/no questions (Item). For each combination of Subject and
Item, the variable Response is coded as 0 or 1.
I want to include random effects for both Subject and Item. While I
understand that the datasets are fairly small, and there are a lot of
invariant subjects, I do not understand something that is happening

Bug in as.character? (PR#14206)
A long formula which is converted using as.character, looses its last
part: ``diagonal = 1e-12)''
Shorter formula is ok though.

Help with averaging
Hi
I am using the following script to average a set of data 0f 62 columns into 31 colums. The data consists of values of ln(0.01) or -4.60517 instead of NA's. These need to be averaged for each row (i.e 2 values being averaged). What I would I need to change for me to meet the conditions:
1. If each run of the sample has a value, the average is
given
2. If only one run of the sample has a

strange strsplit gsub problem 0 is this a bug or a string length limitation?
I was working with the rmetrics portfolioBacktesting function and dug into
the code to try to find why my formula with 113 items, i.e. A1 thru A113,
was being truncated and I only get 85 items, not 113.
Is it due to a string length limitation in R or is it a bug in the strsplit
or gsub functions, or in my string?
I'd very much appreciate any suggestions

how to specify ggplot2 facet plot order
Hi, new to R and ggplot2. I've been trying to get a facet plot in which the
order of the facets is as I require, rather than ordered numerically,
alphabetically, by Roman numerals, mean (answers to these were posted here
after much searching). Here's some test code to demonstrate what I get.

ggplot2 boxplot confusion
Ultimately my aim is to get a plot of density faceted by 2 factors with a
horizontal boxplot overlaid on each density plot in the grid to indicate
summary stats. So I've been experimenting with creating boxplots and density
plots. Here's some representative data.

script.aculo.us: pause before effect.appear
I''ve created a simple script (below) which calls the effect.appear script in
order to make a group of items appear at the page load. I would like to have
the images randomly appear at different times; e.g. the 3rd image might
start appearing 2 seconds after load, the 6th image immediately after load,
the first image 1 second after load, etc...
How can I achieve this affect?

Hello,
I'm a bit new to the world of R so forgive my ignorance. I'm trying to do a zero-inflated negative binomial regression and have received an error message and i'm not sure what it means. I'm running R 2.5.1 on XP. I have just tried a really simple version of the model to see if it would run before I put all the variables in. I have attached all the variables to the

Formatting output of plotKML
Hello,
I previously submitted the below query to r-sig-geo, but have had no

Error using the mi package
I'm trying to impute data using the mi package, but after running
through almost the entire first round of imputations (which takes
quite a while), it throws this error (I'll include the whole output
prior to the error for context). Does anyone know what is causing it,
or how I can fix it?
More specifically, how can I tell what is throwing the error so I know
what to fix? Is
