Cleveland dot plots
I would rather use cleveland dot plots than bar charts to display my study
results. I have not been able to find (or figure out) an R package that is
capable of producing the publication quality dot charts Im looking for. I
have either not been able to get error bars (lattice), cannot order the data
display properly (latticeExtra), or cannot make adjustments to axes. Does
anyone have a quick

Cleveland's Cut-and-Stack Plot
Hi,
Is there a function in R that does Cleveland's Cut-and-Stack plot (Page
190 -- 191, The Elements of Graphing Data, William S. Cleveland)?
Or do I need to do it the hard way, i.e. set par(mfrow = c(m, n)) then do
it one-by-one?
(I have a time series data set that is almost identical to the description
in Cleveland's book, hence I'm interested in trying the Cut-and-Stack
plot)

Variance component estimation in glmmPQL
Hi all,
I've been attempting to fit a logistic glmm using glmmPQL in order to
estimate variance components for a score test, where the model is of the
form logit(mu) = X*a+ Z1*b1 + Z2*b2. Z1 and Z2 are actually reduced rank
square root matrices of the assumed covariance structure (up to a constant)
of random effects c1 and c2, respectively, such that b1 ~ N(0,sig.1^2*I) and
c1 ~

Question about Package 'sampleSection' for IRT model
Dear All,
I am Ph.D student at Chulalongkorn University in Thailand, I want to use Package 'sampleSection' to estimate missing data which generate under IRT model(3-PL);
n<-500 ## number of examinee
I<-20 ## number of items
num.imp<-5 ##number of imputations
p.missing<-c(0.09, 0.01) #prob of missing
theta<-sort(rnorm(n,0,1)) #ability
a<-rnorm(I,0.5,0.1) #discrimination

is there an equivalent of prop.table but for counts
I have a simple table below called temptable and i want to obtain the
same structure that prop.table creates except get the counts
rather than the proportions. margin.table seems to create one table with
columns and rows whereas I am looking for the three table
type structure that prop.table gives. Thanks.
temptable<-structure(c(0L, 2L, 0L, 1L, 0L, 0L, 0L, 0L, 0L, 1L, 0L, 0L,
0L,
0L, 0L,

converting a table to a dataframe or a matrix
can someone show me how to convert a table to a data.frame or a matrix ?
I tried below and as.data.frame rearranges the columns
similarly to a melt from reshape and as.matrix didn't change it. I
actually would prefer to change it to a dataframe but if someone
can show me how to convert it to a matrix, then as.data.frame will work
on that. I was thinking about just changing the class to

smooth line overlap with histogram
Hi r-users,
I would like to overlap a smooth line on the histogram. I tried using spline but it does not work.
sq <- seq(0,900,by=50)
sq.50 <- as.character(sq)
datobs <- sum_pos
## first, plot histogram
histo <- hist(datobs,breaks=sq,freq=F)
## extract counts from histogram and calculate the probability in
## each specified interval. Also check the length of the interval is

using barchart in lattice package and conditioning
I have the data structure below and I'm attempting to send it into
barchart using the R code below it. I don't get an error but I don't get
any output either. Deepyan's new Lattice book is amazing and there are
some examples sort of similar to what i'm doing but I couldn't see a
way of using the formula interface to condition on what I wanted to
condition on so I
