Hi, R-listers,
Failed, when I tried to merge df1 and df2 by "codetot" in df1 and "codetoto"

how to fill the area under the density line with semitransparent colors
Dear R-listers,
I have created a plot to display the density lines for the same
variable by different entities. Now, I want to fill the area under the
density lines with semitransparent colors.
Though I have checked that in web-searching and book-reading, I still
do not perform that.
Could anyone please give me any helps or advice? Thank you in advance.

how to calculate the consistency of different clusterings
Dear R-listers,
I do clustering on tens of individuals by thousands of traits. I have
known the assignment of each individual. I want to classify the
individuals by randomly resampling different subsets of the traits,
for example, randomly resampling 100 traits for 100 times, then 200
traits for 100 times, then 300 traits for 100 times, ,,,,,,. By each
subset of traits, I do clustering of the

List of tables rather than an extra dimension in the table or (l)apply(xtabs)
I'm not sure how to best explain what I am after but here goes. I have a data frame with 2 geographical factors. One is the major region the other is the component regions.
I am trying to process all the regions at the same time without using "for". So I need (think, I do) a list of matrices each structured according to the number of subregions within each region.

quick question about binary data
Dear all,This is both an R and a statistics question. I want to test whether males and females of a given species tend to co-occur in a given sampling unit more frequently than expected by chance. I'm thinking about using a binomial distribution with p as the sex ratio of the entire population. So, even though the population sex ratio is close to 50:50, each sampling unit would have

Error in lmer: asMethod(object) : matrix is not symmetric [1, 2]
Dear R Users,
I am having trouble with lmer. I am looking at recombinant versus non
recombinant individuals. In the response variable recombinant
individuals are coded as 1's and non-recombinant as 0's. I built a model

first fixed effect and sexual genotype (XY, YY, WX and WY) the second

split a character variable into several character variable by a character
Dear Mao Jianfeng,
"r-help-owner" is not the place for help, but:

In any case, strsplit() does the job, i.e.:
> unlist(strsplit("BCPy01-01", "-"))

You can work with the whole variable, like:
splitpop <- strsplit(df1$popcode, "-")

random effects model
Hi A.K
Regarding my question on comparing normal/ obese/overweight with blood
pressure change, I did finally as per the first suggestion of stacking the
data and creating a normal category . This only gives me a obese not obese

models.

Precision in R
Greetings.
I'm trying to recreate in R some regression models I've done in SAS,
but I'm not getting the same results. My advisor suspects this may be
due to differences in precision between R and SAS. Does anyone know
where I can find specifications for R's type double? (It doesn't seem
to be in the R Language Definition.) Thanks in advance for any help

how to generate a normal distribution with mean=1, min=0.2, max=0.8
Dear all,
This is a simple probability problem. I want to know, How to generate a
normal distribution with mean=1, min=0.2 and max=0.8?
I know how the generate a normal distribution of mean = 1 and sd = 1 and
with 500 data point.
rnorm(n=500, m=1, sd=1)
But, I am confusing with how to generate a normal distribution with expected

Dear all,
I'm testing the effect of species and sex in my sample by using the principal component scores of a PCA analysis.
I have 30 PCs and I tried to see if there is any significant difference from males to females, given that there is a significant effect of phylogeny (factor with several species).
I didi it like this:

I would like to report the following bug or maybe you can explain if I am

populations have the same age groups and I want to distinguish where I am

multiple lty on same panel in xyplot
I would like to use lattice graphics to plot multiple functions (or groups
or subpopulations) on the same plot region, using different line types "lty"
or colors "col" to distinguish the functions (or groups).
In traditional graphics, this seems straightforward: First plot all the data
