efficient code. how to reduce running time?
Hi,
I am new to R.

It is taking forever and I can't use it like this.
I was wondering if you could help me find ways to fix the code to run
faster.
Here are my codes..

[PATCH 0 of 3] Support for VM generation ID save/restore and migrate
This patch series adds support for preservation of the VM generation ID buffer
address in xenstore across save/restore and migrate, and also code to
increment the value in all cases except for migration.
The first patch modifies creation of the hvmloader key in xenstore and adds
creation of a new read/write hvmloader/generation-id-addr key.

This patch series adds support for preservation of the VM generation ID

The vast majority of the code is in second patch. The first patch
merely changes the xenstore key name used by hvmloader to store the

dynlm and lm: should they give same estimates?
Hi,
I was wondering why the results from lm and dynlm are not the same for what I think is the same model.
I have just modified example 4.2 from the Pfaff book, please see below for the code and results.
Can anyone tell my what I am doing wrongly?
Many thanks,

A nice guy call Jun Shen was helping me out with this, but I require a bit more help. Below is my data set or list called 'test'. I'm trying to calculate the %RSD for each pair of index and keep it in cronological order if you can imagine a 3rd column with 'date' beside index.

logLik == -Inf in gls
I am trying to fit a generalised least squares model using gls in the nlme
package.
The model seems to fit very well when I plot the fitted values against the
original
values, and the model parameters have quite narrow confidence intervals
(all are
significant at p<5%).
The problem is that the log likelihood is always given as -Inf. This
doesn't seem to make sense because the model

multi-comparison of means
Hi all:
I have a question about multi-comparison.
The data is in the attachment.
My purpose:
Compare the predicted means of the 3 methods(a,b,c) pairwisely.

[PATCH 1/5] fat: fix minfatsize for large FAT32
Hi Ady,
Your insightful post prompted me to to a little bit more digging as to
how the Ridgecrop algorithm computed its FAT size, with the result of my
investigations presented below.
NB: For those who don't want to go through this whole part, there's a
TL;DR near the end.
For reference, the computation of the FAT size all done in the

[PATCH 0 of 6] Add support for a VM generation ID virtual device (v2)
The following is a revised patch series to add support for a
VM generation ID virtual device for HVM guests.
The basic requirements of this device are as follows:
- It must be exposed somewhere in ACPI namespace with a _CID of
"VM_Gen_Counter".
- It must also include a _DDN of "VM_Gen_Counter".
- It must contain a _HID object but no particular value is
required.
- It must

Sorry if I wasn't clear. I think I implied that the Large FAT32 fat size
had an extra sector compared to minfatsize, when of course I meant the
opposite (the Large FAT32 has one less sector than the minfatsize

'for Loop'
Hello,
I'm trying to create a for loop for a data set, I have a list of results in this data set and I want to take the 1st two add them together and divide by the mean of the 1st to, then do the same for the 3rd and 4th values in the list and so on and each time return a value for the calculation on each pair.
Any help would be appreciated.
Thanks,
