different interface to by (tapply)?
dear R experts:
has someone written a function that returns the results of by() as a
data frame? ??of course, this can work only if the output of the
function that is an argument to by() is a numerical vector.
presumably, what is now names(byobject) would become a column in the
data frame, and the by object's list elements would become columns.
it's a little bit like flattening the by()

best method to format output of frequency table
I have some security alert log data that I'm parsing and doing some stats on.
One of the fields is the "Classtype" which is the enumerated value of the
type of alert found.
classtypes = factor( alerts$Classtype )
fclass_types = table( classtypes )
fclass_types gives me a frequency table of the intrusion types:
fclass_types

[LLVMdev] GSOC 2012 Proposal Idea - Flexible and Efficient Realizations of Logic Based Languages.
To Whom It May Concern:
My name is Daniel DaCosta.
I am a first year PhD Student at the University of Minnesota.
I am working with the Programming Languages group at UMN.
I am interested in type theory and logic based languages, including both
practical and theoretical applications.
I am inquiring about a proposal that would involve either toolchain
extensions or proof of concept implementation

How to represent Story of Life grid in Then clause
In this story from Dan''s Game of Life:
Scenario: the grid has three cells
Given 3 x 3 grid
When I create a cell at 0, 0
And I create a cell at 0, 1
And I create a cell at 2, 2
Then the grid should look like:
XX.
...
..X
How do you set up matchers for the grid at the end. Are all the
indented lines after a Then passed to the Then matcher as separate

How to represent factor levels & ordiellipses using different colors?
Dear Jari Oksanen,
I am Trinadh Kumar, a student of Biotechnology from Texas Tech University.
I have a question for you regarding constrained ordination graphs.
I had previously plotted constrained ordination graphs using distance based
redundancy analysis for species data on patients.
The species matrix consists of 70 patients and 274 species of bacteria.The
metadata matrix consists of 10

How can I represent a shape using 1-D discrete wavelet descriptor s?
I only concern about the boundary of the shape and I don¡¯t concern gray
level.
U[m] = x[m] + jy[m] m= 0,1,¡,N-1 is the N points on the boundary.
It is easy to express U as a discrete Fourier series.
But it seems like that wd in the wavethresh package cannot deal with complex
values.
And it is not interesting to transfer U to a matrix.
Thanks a lot

Does the "labpt" object in the Polygons-class represent the centroid of the polygon
Hello,
I need to calculate the centroids of some spatial polygons that I have
placed into a Polygons-class object. Is the labeling point in the
Polygons-class the centroid of the polygon?
Thank you for your help.

best way to represent this pseudocode in LLVM IR?
Greetings,
I implemented a proof of concept of something I'm calling "error return
traces" in my frontend (screenshot and explanation at this link):
https://github.com/zig-lang/zig/pull/684
Now I'm trying to minimize the runtime size.
Here's some example IR that I generate:
define internal fastcc i16 @baz1(%StackTrace* nonnull) unnamed_addr #2 !dbg

You should use the @llvm.stacksave and @llvm.stackrestore intrinsic.
It is only legal

That seems extremely weird... what sort of magic is objc using

[LLVMdev] Is LLVM expressive enough to represent asynchronous exceptions?
Hi Sohail,
> Is LLVM expressive enough to represent asynchronous exceptions?
not currently. The first step in this direction is to get rid of the invoke
instruction and attach exception handling information to basic blocks. See
http://nondot.org/sabre/LLVMNotes/ExceptionHandlingChanges.txt
for a discussion.
Ciao, Duncan.

In IR? In the form of synchronous exceptions?
How can you possible represent a "signal cfg" in IR? Is there a need
for unwinding information at all?
