Extracting columns
Hi,
I have 22 files (A1, A2, ..., A22) with different number of columns,
totaling 10,000 columns: c1, c2, c3, ..., c10000
I have another file with a list of 100 columns that I need to extract.
These 100 columns are distributed in 22 files.
How to extract the 100 columns of the 22 files?
I have done it "manually" with the following commands, for example:
cromo1 = read.table ("~ / cromo1.raw ',...

ROCR package question for evaluating two regression models
Hello All,
I have used logistic regression glm in R and I am evaluating two models both learned with glm but with different predictors. model1 <- glm (Y ~ x4+ x5+ x6+ x7, data = dat, family = binomial(link=logit))model2 <- glm (Y~ x1 + x2 +x3 , data = dat, family = binomial(link=logit))
and I would like to compare these two models based on the prediction that I get from each model:

animating plots over time with a slider
...for other simple applications, but hit two problems - firstly it doesn't like dates as a slider variable. I can work around this by making them numeric, but would like to work with dates if possible. Secondly I don't know how to restrict observations to the date on the slider - eg. Subject 100 has a baseline of 45.26, but on or after 26th April it becomes 56.96. So where the slider is set beyond this date I would want the earlier value for this subject to be excluded from the distribution. I'm not sure that manipulate was really made for this problem and perhaps I should be looking...

cumulative frequency plots for factors
Dear list,
I have a data frame with a number of events (factor) and the times at which they occurred (continuous variable):
event time
A 10
A 12
B 15
A 17
C 13
...
Is it possible in R to make a plot against time of the cumulative frequency of occurrence of each event? This would be, a raising line for each factor.
Regards,

Biclust package: drawHeatmap()
...heatmap of the bicluster results. With the code given in the biclust package I can only get the heatmap for one cluster at a time (drawHeatmap function). Is there any way that I can get the heatmap for all the clusters at the same time?
The code that I am using (biclust documentation) is:
#Random 100x50 matrix with a single, up-regulated 10x10 bicluster
s2=matrix(rnorm(5000),100,50)
s2[11:20,11:20]=rnorm(100,3,0.3) # cluster 1
s2[31:40,31:40]=rnorm(100,5,0.7) # cluster 2

Biased calculations from using rmultinom?
Dear R users,
This is a problem that has puzzled me for quite some time, and I wonder if
anyone could offer me an insight to what is happening?
I generated a multinomial matrix by using
A<-rmultinom(100,1,c(0.4,0.3,0.2,0.1), and multiply this matrix by a set of
values say B<-runif(n,100,50). I then calculate var(colSums(A*B)). I was
able to work out the theoretical mean of var(colSums(A*B)) by using
fun.var.match.gen below.
I was however not sure, why is there a persistent over estimate fro...

intersecting polygons and conversion from decimal degree to km
Dear all,
1. How can I compute the intersecting area between 2 polygons ?
2. I have polygons with coordinates in decimal degrees (i.e. 13 deg 30
min = 13.5 decimal degrees). I want to compute their area and get the
results in square meters or square kiometers. Can anyone give me a
conversion coefficient or a pointer where I can find this information
(sorry for this off topic question) ?
Thanks

[PATCH 0/9] virtio: new API for addition of buffers, scatterlist changes
Most device drivers do not need to perform any postprocessing on the
scatterlists they receive from higher-level drivers (e.g. the block
or SCSI layer), because they translate the request metadata directly
from the various C structs into the data that is required by the device.
virtio devices however do this translation in two steps: a device-specific
step in the device driver, and generic

[RFC PATCH 0/8] virtio: new API for addition of buffers, scatterlist changes
The virtqueue_add_buf function has two limitations:
1) it requires the caller to provide all the buffers in a single call;
2) it does not support chained scatterlists: the buffers must be
provided as an array of struct scatterlist.
Because of these limitations, virtio-scsi has to copy each request into
a scatterlist internal to the driver. It cannot just use the one that

Preparations for Fermi DRAM clock changes
No, no, these will not implement Fermi reclocking. This set of patches
contains some of the preparatory work that I deem stable enough to
move upstream. Notable changes
- Training pattern upload routines from GK104+ now shared with GT215+
- Timing calculation for Fermi
- GDDR5 MR calculation from VBIOS timing table v1.0. Also useful for that
pesky GT 240.
- A routine to translate a VBIOS init

in other people's trees. Sorry for the noise.
