hi all
why does the following not work???
this was someone elses code and i couldnt explain why it doesn't work.

Question regarding R plot
Hi, I am new to R, and have a quick question regarding an R script
that I received from a kind colleague.
I am trying to determine the "peak" (maximum value) of the graph that
is plotted when executing the following. There is an input file called
"rates_values.txt" which begins as:
rateValue

[LLVMdev] LLVM optmization
The following C test program was compiled using LLVM with -O3 option and MSVC with /O2.
The MSVC one is about 600 times faster than the one compiled with the LLVM.
We can see that the for loop in MSVC assembler is solved in the optimization pass more efficiently than that in LLVM.
Is there an way to get a optimization result in LLVM like that of the MSVC?

symbolic computing example with Ryacas
Thanks for the response. Yes, I did study the vignette but did not
understand it fully. Anyway, I have tried once again now. I am happy to say
that I have got what I wanted.

my_func <- function(x,U,x0,C) {

[LLVMdev] BlockAddress instruction is copied instead of cloned during module link?
I have a module having the blockaddress instruction.
When I link it into another module and delete the original, blockaddress
disappears and is replaced by inttoptr (i32 1 to i8*).
Please compile and run the attached program to see the demo of this
problem.
Right after linking modules, blockaddress still exists:
@switch.bbs = internal global [3 x i8*] [i8* blockaddress(@my_func,

Question: write an R script with help information available to the user
Dear All,
I would like to ask a question on how to incorporate into an R script help information for the user. I vaguely recall that I saw some instructions on an R manual, but am not able to figure them out. Hereunder is the basic setting:
1. I finished writing an R script, my_script.r, that is a function (the function is named "my_func") for a statistical procedure. This means that

'apply' with additional class variable
Dear R gurus,
I'm trying to solve what I assume is a fairly simple problem, but I'm having trouble finding the proper approach. I have a matrix where each column is some object (e.g. a car) and each row is a numeric measurement of a feature of said object (e.g. horse power, top speed, etc.). Let's also suppose that I know what make the car is (e.g. toyota, ford, etc.), stored in a

adding text to y-axis per row of panels (lattice)
Dear all,
Being a newbie to R, I've trawled through many old posts on this list
looking for a solution to my problem, but unfortunately couldn't quite
figure it out myself. I'd be very grateful if someone here on this
list could perhaps help me out.
I have a lattice plot with several panels and would like to add some

[LLVMdev] LLVMdev Digest, Vol 55, Issue 16
1. Re: LLVM optmization (Bill Wendling)
Hi,
The IR is not wrong. I said that the assembler generated by MSVC is quicker. We can see that the for loop, in the TESTE function, is done without jump's in the MSVC and with jumps in LLVM. I think thats the point.
If we don't use threads, the result is the same. My test were done with one billion interactions in the for loop. The MSVC

I try to do a scatterplot for a bunch of variables. I plot a dependent

tapply with multiple arguments that are not part of the same data frame
Hi all,
I would like to invoke a function that takes multiple arguments (some of
which are specified columns in the data frame, and others that are
independent of the data frame) on split parts of a data frame, how do I do
this?
For example, let's say I have a data frame
