allocating factor levels
Dear R users,
I am working on allocating the rows within a dataframe into some
factor levels.Consider the following dataframe:

2 Start.setting 2010-12-30 18:40:00

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

[LLVMdev] __main() function and AliasSet
In a code segment of my pass plugin, I try to gather AliasSets for all StoreInst, LoadInst and CallInst instructions in a function.
Some behaviors of the pass puzzled me.
Below is the *.ll of the test program which I run the pass on,

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"

Length of dial string
Hi Dovid
Yes was one of the options but as the required list is dynamic becomes very
messy - and all combinations problem - where as "call all workers job xxx"
is what is needed so the ability to call 20+ numbers is what is needed - agi
does a database search for all jobx workers and constructs a dialstring with
SIP, DAHDI and Local devices.
Can someone tell me where to find maximum

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:

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))

[LLVMdev] Re: __main() function and AliasSet
Oh, I appologize that I should not have asked about __main() ---- it appears
in FAQ.
But the question remains that why call to __main() can alias stack location?
I think the memory location pointed by data_X pointers are not visible to
__main().
In comparison, calls to printf() do not have similar effect.

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.

[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

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.

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

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

Hi Chris,
I took a haste look at the "Points-to Analysis in Almost Linear Time" by Steens , your PHD thesis
and SteensGaard.cpp in LLVM this afternoon.
So I think:

Right, steens-aa and ds-aa share code for "local analysis", they just
stitch it together into an interprocedural analysis in different ways.
The code below is used for steens-aa.

If you've tested it then, yes you're right :). I haven't played with this
