How to control spaces between axis, tick and label in xyplot or xYplot?
Dear R users,
I encounter a problem regarding space control in xyplot. Basically, I want
to control spaces between label, tick and axis. I remember there is a
function called mgp in general plot. Is there a similar function for xyplot
or xYplot?
Below is my basic code:
myplotkid<-xyplot(expected_offspringnumber~afr|decade,groups=SES,data1,

Why there is no p-value from likelihood ratio test using anova in GAM model fitting?
Hello, everybody,
There is the first time for me to post a question, because I really cannot
find answer from books, websites or my colleagues. Thank you in advance for
your help!
I am running likelihood ratio test to find if the simpler model is not
significant from more complicated model. However, when I run LRT to compare
them, the test did not return F value and p-value for me. What's the

family
Hi all,
I am reading a huge data set(12M rows) that contains family information,
Offspring, Parent1 and Parent2
Parent1 and parent2 should be in the first column as an offspring
before their offspring information. Their parent information (parent1
and parent2) should be set to zero, if unknown. Also the first
column should be unique.
Here is my sample data set and desired output.

[Fwd: Re: subsetting]
Sorry that I was unclear. For an individual to qualify for my analysis I
want both of the following two criteria to be fulfilled:
First, I want to select measurement taken at a certain age: for the
focal individual the year of measurement (year) should be the same as
year.hatch
Second, I want the focal individual to be born by a mother that
reproduces for the first time.
So the /parents /of

re ferring to data of previous rows
Dear Rlers,
in the following dataset I would like to insert a new column that refers to
the data of the previous row.
My question is whether the probability of a female (Id) changes if she had
given birth to a pup in the previous year. So my dataframe consists of the
column Id, year (2003-2007 for each Id) and offspring (=of; 1-0):

Overlying a Normal Dist in a Barplot
R-Users,
Hopefully someone can shed some light on these questions as I had
little luck searching the archives (although I probably missed something
in my search due to the search phrase). I estimated multinomial
probabilities for some count data (number successful offspring) ranging
from 0 to 8 (9 possible response categories). I constructed a barplot

sample
Hi,
I am sampling two random columns from females and two random columns
from males to produce tetraploid offspring. For every female I am
sampling a random male.
In the end I want to write out a a matrix with all the offspring, but
that does not work. I get always only the offspring from the last
females. There must be a mistake in my script:

loop over large dataset
Hi All,
I'd like to ask for a few clarifications. I am doing some calculations
over some biggish datasets. One has ~ 23000 rows, and 6 columns, the
other has ~620000 rows and 6 columns.
I am using these datasets to perform a simulation of of haplotype
coalescence over a pedigree (the datestes themselves are pedigree
information). I created a new dataset (same number of rows as the

A random insertion position in a vector
A student asked me about simulation he is doing. This simulation
presented an interesting R programming puzzle that we did solve but I
am not happy with the solution. I feel there should be a better way
of doing this.
Briefly, he is simulating births and deaths in a linear array of cells.
Births and deaths are required to alternate.
For a birth, one of the cells is selected at random to be the

Generating unique permutations of a vector
Hi all,
I try to generate sets of strategies that contain probability
distributions for a defined number of elements, e.g. imagine an
animal that can produce 5 different types of offspring and I want to
figure out which percentage of each type it should produce in order to
maximize its fitness. In order to do so, I need to calculate the fitness
for all potential strategies. As an example, if I

oggenc of wav file loses one second at end of track.. why?
Hi,
I recently noticed that a relativly short wav file
loses the last second (truncated perhaps) when I ran
it through oggenc. Originally the wav was 25 seconds,
the ogg is 24 seconds.
This happens at various quality levels, and I saved
several copys of the file on a webserver at

Recoding multiple columns consistently
Hi,
I have a dataframe that contains pedigree information;
that is individual, sire and dam identities as separate
columns. It also has date of birth.
These identifiers are not numeric, or not sequential.
Obviously, an identifier can appear in one or two columns,
depending on whether it was a parent or not. These should
be consistent.
Not all identifiers appear in the individual column - it
