The confidence level of p-value of ks.boot
Hello!
I need to compare 2 datasets whether they come from the same distribution. I use function ks.boot{Matching}. And what is the confidence level of the p-value, returned by ks.boot function?
The code is:
set=read.table("http://stella.sai.msu.ru:8080/~gala/data/testsets.csv",
header=T,sep=',')
set1=set[!is.na(set$set1),'set1']

allocating factor levels

extracting vectors from lists of lists
Good evening
I often have as output from simulations a list of various values, vectors
and matrices.
Supposing that I then run said simulation several times, I often want to
extract a particular result from each simulation for plotting and,
ideally, put it in a matrix.
A simple example
v1 <- 1:5
v2 <- 6:10
other1 <- "stuff"
other2 <- "stuff"

UNIX diff function
Colleagues,
(R: 2.13.0; OS X)
I often receive sequential datasets in which there are new rows interposed between existing rows. For example:
SET1 <- data.frame(list(LETTERS=LETTERS[c(1:4, 6:10)], NUMBERS=c(1:4, 6:10)))
SET2 <- data.frame(list(LETTERS=LETTERS[1:10], NUMBERS=1:10))

But then you need to teach a bunch of places about how to simply them,
fold using bitwise logic and other things that reduce demanded bits into
them, etc. This seems like a difficult tradeoff.

Problem with the aggregate command
Dear friends,
I have a data set with 23 columns and 38000 rows. It is a panel running from the years 1991 through 2005. I want to aggregate the data and get the medians of each of the 23 columns for each of the years. In other words my output should be like this
Year Median
1991 123
1992 145
1993 132
etc.

How to change a venn command into a named object that can be plotted like a lattice object
Hello,
I am plotting data as a venn diagram but would like to be able to control how it is plotted like a lattice object.
Right now, it plots right away. I would like to name it and then plot at will.
I thought to convert the whole thing to a PostScript file then get it back into R via grImport, but surely (please!) there must be a less roundabout way to do this.
Any help is appreciated.

For loop to cycle through datasets of differing lengths
I have encountered this problem on several occasions and am not sure how to
handle it. I use for-loops to cycle through datasets. When each dataset is
of equal length, it works fine as I can combine the datasets and have each
loop pick up a different column, but when the datasets are differing
lengths, I am struggling. Here is an example:
A<-1:10
B<-1:15
C<-1:18

[RFC] bitfield access shrinking
In http://lists.llvm.org/pipermail/cfe-commits/Week-of-Mon-20120827/063200.html,
consecutive bitfields are wrapped as a group and represented as a
large integer and emits loads stores and bit operations appropriate
for extracting bits from within it. It fixes the problem of violating
C++11 memory model that original widen load/store of bitfield was
facing. It also brings more coalescing

Smart Indexing
Hi all,
Suppose that I've two data frames, a and b say, both containing a column
'id'. While data frame 'a' contains multiple rows sharing the same id,
data frame 'b' contains just one entry per id (i.e. a 1 to n
relationship). For the ease of modeling I now want to generate a new
data frame c, which is basically a copy of data frame 'a' augmented by
the values

Quickly generate all possible combinations of 2 groups
Hi all,
I suspect the answer to this query will be the tongue-in-cheek "use a
quantum computer", but I thought my understanding might be
sufficiently limited that I'm missing a simpler option.
I'm looking for a way to cycle through all possible combinations of 2
groups of data. For 10 data points, that's 2^10 combinations, for 20
data points it's 2^20, etc. combn() from

Cutting heatmap dendrogram
Hello,
I've been clustering my data using hclust and cutting the resulting tree
with cutree. Separately, I visualize the clusterings with heatmap. Is it
possible to have the dendrogram on the heatmap reflect the cutree results?
That is, instead of having one large dendrogram, it would have 4 or 25 in
the example below. Any guidance on if that's possible or not, and what
kinds of

the new package "sets"
Dear Sirs
I can't try the package sets because I have a old mac system. Package
sets needs R = 2.6. I need to group some variables into a set of new
variables defined by a particular modality:
Example:
my.df = data.frame(var1=c(1,2,2,1,2,2,1,2), var2=c(2,2,1,1,2,2,1,1),
var3=c(1,2,2,1,1,1,1,2), var4=c(1,1,1,1,2,1,2,1))
I'm looking for a way to compute set1 and set2?

Help implementing a simple Python port

I wonder if anyone might be able to help me troubleshoot an attempt at
porting some simple Python code to R.
The function below is supposed to take a matrix containing item ratings from
various users and, given a vector containing at least 1 rating and 1 missing
value, employ a 'weighted slope one' algorithm to predict the missing
values.

Multiple options for a package
Hi R-devel,
I am facing a situation where the number of options I would like to propose
to the user is somewhat big (and could easily increase more and more as I
will code up a little more - even coming to a point where an user should be
able to implement his own options).
What we have to handle options is the couple:

use variable in for loop to name output files
Hi,
This question should be simple to answer. I am a new R user.
I have a data.frame called appended. I would like to break it into 7 smaller
datasets based on the value of a categorical variable dp (which has values
1:7). I would like to name the smaller datasets set1, set2, set3,....,set7.
I don't know how to refer to the variable in the for loop, when naming the
output datasets. In STATA
