when vectorising does not work: silent function fail?
Dear All,
I'm using apply to do some genetic association analysis along a chromosome, with
many thousands markers. For each marker the analysis is the same, so I was
planning to use apply(chrom, 2, somefunction)
In the specific case I do:
my.results = apply(chr, 2, function(x){anova(lrm( cpstc.f ~ x + time.cpstc + age
+ sex + mri))[1,3]})
This is all good and well in theory, but in

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
pedigree

vectorisation suggestion
Hi All,
I am counting the number of occurrences of the terms listed in one
vector in another vector.
My code runs:
for( i in 1:length(vector3)){
vector3[i] = sum(1*is.element(vector2, vector1[i]))
}
where
vector1 = vector containing the terms whose occurrences I want to count
vector2 = made up of a number of repetitions of all the elements of
vector1
vector3 = a vector of NAs that is

cox model for haplotypes
Hi,
Anybody knows a function that can fit haplotype data to a Cox model.
I've been searching it in the web without succeed.
I use "haplo.stats" package, but unfortunatelly it's not possible to
analyse survival data, amb I right?.
Thanks in advance.

infer haplotypes phasing trios tdthap
Dear R mailing list,
I have a dataset with genotypes from trios and I would like to infer
haplotypes for each mother, father and child. The package that I could
find that can do this is tdthap.
But when the mother is homozygous (e.g., 2/2) the haplotype is called as
not possible to infer (0); I would prefer for it to call the genotype
(2). From what I understand it is doing what I would like

EM algorithm for multiple-locus haplotypes frequencies

I've been looking in R for an EM algorithm adjusted for multiple-locus
haplotypes frequencies, but failed in 100%. Has anyone heard of
anything of this kind in R?
Thanks in advance,

removing message: [Previously saved workspace restored]
Dear All,
I saved by mistake the environment I was working in after typing q(),
and now I get the annoying message:
[Previously saved workspace restored]
I have already deleted all the objects in the environment, saving it as
an empty environment, so it's just a matter of nitpicking I suppose. The
message does not appear if I start R from any other place in the
directory tree.

Making a new package: licence
HI All,
I have written and succesfully uploaded a new package. The licence it is under is 'GPL' --no version. My assumption is, since all the code is written in R the licence R used for R would affect the code (hence my "GPL" stands for "whatever version of the GPL R is under")
I am happy with the licencing I used, but I'd like to ask if there is any transitive

logical subsetting, indexes and NAs
Dear All,
just a quick example:
> x = 1:25
> x[12] = NA
> x
[1] 1 2 3 4 5 6 7 8 9 10 11 NA 13 14 15 16 17 18 19 20 21 22 23 24 25
> y = x[x<10]
> y
[1] 1 2 3 4 5 6 7 8 9 NA
Is there any way of NOT getting NA for y = x[x<10]? Similarly
> y = x[x<15]
> y
[1] 1 2 3 4 5 6 7 8 9 10 11 NA 13 14

writing summary() to a text file
Hi All,
I would like to output the results of a function into a text file,
legible as a such. The function produces a summary quite like:
summary(lm(x ~ y + w * z))
[for instance]
and I am not clear how to save this summary into a text file
'automagically', because I need to be able to do it in a for() loop.
Cheers,
Federico

putting stuff into bins...
Hi All,
I have a vector of data, a vector of bin breakpoints and I want to put my data
in the bins and then extract fanciful informations like the mean value of each bin.
I know I can write my own function, but I would have thought that R should have
somewhere a function that took as arguments something like (data, breaks, what
to do with the data in the bins). I surey could not find it
