serial subtraction within a vector
Hello,
I have a vector (numeric) v-> c(a,b,c,d,e) and I want to create the vector
n->c(b-a,c-b,d-c,e-d). How can I do that?
Thank you

Installing lumi and hdrcde
To whom it may concern.
As I would like to analyse some array data I was keen on downloading the
lumi package that depends obviously on hdrcde that is not available for r
2.12.1. I did not find instructions to solve or circumvent this problem.
Installing hdrcde by hand did not work either. It was not detected by
> (.packages(all.available=TRUE))
if installed in the R library.
Thanks

qplot: plotting precipitation data
Dear list,
I wish to plot chromatin precipitation data: I would like to have a
rectangles (x:end-start, y:peak) but I do not have an idea how to define x
(in terms of qplot syntax) and to choose the correct geom.
mydata is a subset of a larger file.

plot: x and y chromosomes are missing
Hello,
I have a list with gene names, fold changes (=expression level) and
chromosomes.
Names fold change chromosome
hz 1.5 2
If I plot fold change versus chromosome (or vice versa):
plot (ch, fc)
I see only the chromosomes with numbers but not those with letter (x and
y). What can I do?
A second question:
How can I add a single line in that plot at a certain

making chains from pairs
Hello,
having a data frame like test with pairs of characters I would like to
create chains. For instance from the pairs A/B and B/I you get the vector A
B I. It is like jumping from one pair to the next related pair. So for my
example test you should get:
A B F G H I
C F I K
D L M N O P
> test
V1 V2
1 A B
2 A F
3 A G
4 A H
5 B F
6 B I

8 C I

fusion of overlapping intervals
Hello,
I have start and end coordinates from different experiments (DNase
hypersensitivity data) and now I would like to combine overlapping
intervals. For instance (see my test data below) (2) 30-52 and (3) 49-101
are combined to 30-101. But 49-101 and 70-103 would not be combined because
they are on different chromosomes (chr a and chr b).
Does anybody have an idea?
Thanks

subset a defined row plus the aforegoing
Hello,
my data is sorted by start.ens (see below). And now I would like to extract
all rows (so called* defined row*s) with type==Expression - subset (df,
type==Expression) - and the aforegoing type==DNase HS (which is not
necessarly row n-1 - assumung that the defined row is n). I dont know how
to add this to my subset command.
Is that possible?
Thanks Hermann

prcomp - surprising structure
Hello,
I did a pca with over 200000 snps for 340 observations (ids). If I plot the
eigenvectors (called rotation in prcomp) 2,3 and 4 (e.g. plot
(rotation[,2]) I see a strange "column" in my data (see attachment). I
suggest it is an artefact (but of what?).
Suggestion:
I used prcomp this way: prcomp (mat), where mat is a matrix with the column
means already substracted followed by a

R encrypt/decrypt
Hello,
I am working on a web system (php) that uses R in the backend, and we need some basic fast encryption/decryption for the underlying mysql database that can be used by both R AND php. It does not need to be top-of-the-line, but just provide some basic level of fast encryption/decryption.
Any suggestions?
Thank you,

Block comment?
AFAIK block comment is not possible
it needs to be implemented in R interpreter and defined in the
parser.'If' solution is not elegant.

Dear List,
According to datacamp support team, r-fiddle.org is not supported. We
asked them to put it down as Professor Maechler suggested it is
a waste of time for the R-help to respond to questions on something
not maintained and severely outdated. If you would like to use

problem with function
Dear list,
I have a problem with defining a function (see below) to read my testfile
(see testfile). My function only returns mydata I wish to work with
attr(mydata, 'fc') as well (for labelling a plot). Principally it works if
I do not insist on this function but it would be much easer if it is
possible to return mydata AND attr(mydata, 'fc') by using a function.

read.csv behaviour
This might be obvious but I was wondering if anyone knows quick and easy
way of writing out a CSV file with varying row lengths, ideally an
initial data read from a CSV file which has the same format. See example
below.
I found it quite strange that R cannot write it in one go, so one must
append blocks or post-process the file, is this true? (even Ruby can do
it!!)
