Hello All, I wanted to perform a fourier transform on high frequency financial data. I have searched and have not found much on this topic for R. I was wondering if anyone has used any libraries for it or have come across any papers I may read. Many Thanks, Neil Gupta [[alternative HTML version deleted]]

R Users, I'm new to R and was wondering how I can show more decimal places when I run commands. If I'm simply running a correlation(ES,YM) how would I increase the number of decimal places R shows? When I run this it shows me .9734044. How can I extend this further? In addition I was running histograms on high frequency data to check a Spread. The spread moves at an extremely granular

Hello: I need to build a system like this for a client: I will have a Linux server in a data room. It will have a web interface where the users may upload files. The files may be: Word, Excel, PDF, tif files, etc. Now, using the web interface, they should be able to brig up a list of files, select a set to print and send them to a local printer that is running as a shared printer on a Windows

Hello R-Users, I came across this link on CodeProject.com and was wondering, if anyone has implemented this and the benefits of doing so. This may also be of some help for others.

Hi, This message is to let the R developers know that the pdfs for the first two volumes of the printed edition of R reference manual are available at, http://www.network-theory.co.uk/R/base/vol1.pdf http://www.network-theory.co.uk/R/base/vol2.pdf I've divided the manual into "core commands" of the base package (control flow, and related programming commands, etc) in Volume 1

Can anyone advise me on some pratical papers or books On Gaussian Copulas? Anything in the genre of Copulas Dummies Would be a help. As simpe, and approachable with minimal pedantic style.

ZONE_DEVICE struct pages have an extra reference count that complicates the code for put_page() and several places in the kernel that need to check the reference count to see that a page is not being used (gup, compaction, migration, etc.). Clean up the code so the reference count doesn't need to be treated specially for device private pages, leaving DAX as still being a special case.

Hello, I have quite a simple problem that I believe can be solved quite easily. I have a dataframe as such: Symbol Date Time Exchange TickType ReferenceNumber Price Size 1 3:YMZ7.EC 12/03/2007 08:30:00 EC B 83916044 13387 9 2 3:YMZ7.EC 12/03/2007 08:30:00 EC A 83916045 13388 1 3 3:YMZ7.EC 12/03/2007 08:30:00 EC B 83916054

Hey all, I'm trying to create a plot of two semi-transparent regions. The reason they need to be partially transparent is so that I can see if there's any overlap. Here's some example code: # BEGIN pdf(file="test.pdf",version="1.4") plot(0,0,type="l",ylim=range(-3,3),xlim=range(-1,5)) polygon(c(0,1,2,3,4,3,2,1,0), c(0,1,2,1,0,-1,-2,-1,0),

ZONE_DEVICE struct pages have an extra reference count that complicates the code for put_page() and several places in the kernel that need to check the reference count to see that a page is not being used (gup, compaction, migration, etc.). Clean up the code so the reference count doesn't need to be treated specially for device private pages, leaving DAX as still being a special case.

Great, more notifiers :( Maybe can live with 1- disable preemption while using
