[LLVMdev] User question, using IRBuilder to generate a llvm.memcpy instruction.
Hello,
If this is not the correct list to ask this question on I apologize.
I am attempting to generate a llvm.memcpy instruction with an IRBuilder but
I cannot find the appropriate way to do this.
Thanks in advance,
Sean

will syslinux work on a harddisk ?
Can someone tell me if syslinux will work on a harddisk ?
I have a 4mb flash device that plugs into the IDE connector
on the motherboard, and i'm trying to get syslinux to work
with it, so I can load a Linux kernel and an initrd.
I'm not having any luck with it.
Then it dawned on me that the boot loader in syslinux might
be expecting a floppy drive rather than an atapi hard disk.

Vector manipulation, for loop needed?
Hi,
I have a vector of time in days t<-1:48.
I have observations and the day they were recorded. I also have a vector, S
which takes different values depending on which day the observation was
recorded. For example if on day 1 all in vector S get a value of 46/48, on
day 2 get 42/48, day 3 38/48, decreasing by 4/48 each time until day 12 gets
the value 2/48. Then for any day greater than 12

Sequences
Hi,
I am trying to make a sequence and am using a for loop for this. I want to
start off with an initial value ie S[0]=0 then use the loop to create other
values. This is what I have so far but I just keep getting error messages.
#To calculate the culmulative sums:
s<-rep(0,207) #as this is the length of the
vector I know I will have
s<-as.vector(s)

Patch for a port forwarding problem in serverloop.c
Hello all,
I encountered a problem when trying to setup a remote portforward
using OpenSSH 3.5p1.
If the port that I was trying to listen to on the remote side
was already in use, a message 'cannot bind to port: 5000' was
written to the syslog, but the connection still persisted.
I had no way on the client side to know that the listening
wasn't taking place. that is, the

Adding Printer Drivers from Windows XP
I am having trouble trying to add printer drivers from Windows XP.
I'm running SAMBA 2.2.7a on SUSE 7.2.
As best I can determine, the problem relates to permissions - Windows
doesn't seem to be able to write the files to the printer driver
directory on the server.
Yet, I can set up an ordinary file share to that same directory and
logged on as the same user, I can read and write the

converting numeric into character strings
Hi,
Im trying to put some numbers into a dataframe , I have a list of numbers
(change points in a time series) like such
[1] 2 11 12 20 21 98 99
but I want R to recognise this as just a character string so it will put it
in one row and column, ideally I want them seperated by commas so I would
have for example

Questions on dividing lists and tapply
Hello R community,
I have two questions about using R.
The first is about dividing each element of a list with another similar
sized list. So, if the first list has two elements and so does the second,
then the result should also be a list with two elements.
For example, the inputs are:
list(matrix(1:6,ncol=2),matrix(1:6,ncol=2))->l1
l2<-list(1:3,2)
I want to get a list, l3 with the

A co-occurrence matrix
Dear R experts,
I have a matrix (from some sort of
classification) like this:
object group

And I need something like this:

Linear model, finding the slope
Hi
for some data I working on I am merely plotting time against temperature for
a variable named filmclip. So for example, I have volunteers who watched
various film clips and have used infared camera to monitor the temperature
on their face at every second of the clip.
The variable names I have used are Normalised ( for the temperature) and
Frame (for the time in seconds).
So I have fitted a

turning list into vector/dataframe
Hi,
I have used this command :
resamples<-lapply(1:1000,function(i) sample(lambs,replace=F))
resamples2<-lapply(resamples,Cusum)
to get a list of 1000 samples of my data. The function Cumsum is defined as
follows:
Cusum<-function(x){
SUM<-cumsum(x)-(1:length(x))*mean(x)
min<-min(cumsum(x)-(1:length(x))*mean(x))
max<-max(cumsum(x)-(1:length(x))*mean(x))
diff<-max-min

Matrix manipulation in for loop
Hi all,
I have a problem with getting my code to do what I want!
This is the code I have:
create.means.one.size<-function(nsample,var,nboot){
mat.x<-matrix(0,nrow=nboot,ncol=nsample)
for(i in 1:nboot){
mat.x[i,]<-sample(var,nsample,replace=T)
}
mean.mat<-rep(0,nboot)
for(i in 1:nboot){
mean.mat[i]<-mean(mat.x[i,])
}
sd.mean<-sd(mean.mat)
return(mean.mat)
}
