similar to: Read big data (>3G ) methods ?

Currently it is assumed PCI device BAR access < 4G memory. If there is such a device whose BAR size is larger than 4G, it must access > 4G memory address. This patch enable the 64bits big BAR support on hvmloader. v3 changes from v2: - Remain original print information v2 changes from v1 as comments by Jan. 1) Set Dynamic MMIO high memory address instead of a fixed number 640G 2) Mask

Hi all, I am having problems importing a VERY large dataset in R. I have looked into the package ff, and that seems to suit me, but also, from all the examples I have seen, it either requires a manual creation of the database, or it needs a read.table kind of step. Being a survey kind of data the file is big (like 20,000 times 50,000 for a total of about 1.2Gb in plain text) the memory I have

Hello, I searched the internet but i didn't find the answer for the next problem: I want to do a glm on a csv file consisting of 25 columns and 4 mln rows. Not all the columns are relevant. My problem is to read the data into R. Manipulate the data and then do a glm. I've tried with: dd<-scan("myfile.csv",colClasses=classes) dat<-as.data.frame(dd) My question is: what

Hi,all I have tried to passthrough GPU card(Nvidia quadro 4000) on the latest Xen unstable version (QEMU is using Qemu-upsteam-unstable, not traditional Qemu). This issue as below: Windows7 64-bit guest will blue screen when GPU passthrough configure 4g memory,blue screen code is 50, and SUSE 11 64-bit guest will always stay at the grub screen. I noticed that it will relocate RAM that

Dear Sirs, How can I revert to an older limma version? Typing "install.packages("limma")" in R gives a list of mirrors. How can I install the version I want after I obtain and untar the file (e.g, limma_2.9.1.tar.gz)? I am running R 2.5.0 on a Linux machine (CentOS 5). When using limma it will not go past the read.maimages command. I get this error: Error in

Hi, this is a problem that occurs in the presence of two libraries (limma, xlsx) and leads to a crash of R. The problematic code is the wrong application of sweep or the product ("*") function on an LIMMA MAList object. To my knowledge, limma does not define a "*" method for MAList objects. If only LIMMA is loaded but not package xlsx, the code does not crash but rather

Dear Hilmar Perhaps this gives an indication of why the infinite recursion happens: ## after calling `*` on ma and a matrix: > showMethods(classes=class(ma), includeDefs=TRUE, inherited = TRUE) Function: * (package base) e1="FOOCLASS", e2="matrix" (inherited from: e1="vector", e2="structure") (definition from function "Ops")

Fix the mistake for debug exception(#DB), overflow exception(#OF; generated by INTO) and int 3(#BP) instruction emulation. For INTn (CD ib), it should use type 4 (software interrupt). For INT3 (CC; NOT CD ib with ib=3) and INTO (CE; NOT CD ib with ib=4), it should use type 6 (software exception). For other exceptions (#DE, #DB, #BR, #UD, #NM, #TS, #NP, #SS, #GP, #PF, #MF, #AC, #MC, and #XM), it

Hi Hilmar, weird. The memory problem seems be due to recursion (my R, version 3.3.3, says: Error: evaluation nested too deeply: infinite recursion / options(expressions=)?, just write traceback() to see how it happens), but why does it segfault with xlsx? Nb xlsx is the culprit: neither rJava nor xlsxjars cause the problem. On the other hand, quick googling for r+xlsx+segfault returns tons of

I'm sorry that I should remove the comment. In fact my question is about the "float (i32)* (float (i32)*)*", why we use this kind of return type instead of just "float (i32)*". Thanks a lot.

I was trying to plot some data in R. I used the following code to draw a loess fit and got the output as >?lines(lowess(log(abs(t(res))), log(abs(t(synthesised)))), col="red") Error in lowess(log(abs(t(res))), log(abs(t(synthesised)))) :?? NA/NaN/Inf in foreign function call (arg 1) Then I thought to use your Limma package for background correction. Do you think it's a right

Dear mailing group, This is my first time here. Glad to have this resource! I am currently trying to load an Excel file into R (limma package loaded) using the source(*name of directory*) command, but it cannot open the file. I renamed the file as .R and .RData, to no avail. The Excel data contains one gene name per row and about 100 data points per gene (columns). I am only used to

"float (i32)* (float (i32)*)*" is not a return type. According to the description of the 'call' instruction in LLVM Assembly Language Reference Manual (http://llvm.org/docs/LangRef.html#i_call) this is a signature of the pointer to function value being invoked (which includes the return type). In your case the full signature is printed because get_ptr returns a pointer to

Hi all, Another comment re: html help in Windows. It seems that we've lost the functionality of being able to browse the other functions in a package. In chm, after calling a help function on 'arrayw' in say package 'limma' in BioC, it was possible to see all of the other functions in the limma package. Now it seems we just get a flat html page with no links to the overall

Changes from v1: - Define new struct hvm_trap to represent information of trap, include instruction length. - Renames hvm_inject_exception to hvm_inject_trap. Then define a couple of wrappers around that function for existing callers, so that their parameter lists actually *shrink*. This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP),

This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP), INTn instruction emulation. Introduce new function vmx_inject_sw_exception() which deliver the software excetion, software interrupt and privileged software exception. Split hardware exception as a seperate function(old function vmx_inject_hw_exception()). Also Passed down intruction length

tools/firmware: remove "_PS0/3" Method Do not expose the ACPI power management "_PS0/3" Method to guest firmware. According to section 3.4 of the APCI specification 4.0, PCI device control the device power through its own specification but not through APCI. Qemu pushes "_PS0/3" to guest will cause a mess between ACPI PM and PCI PM as a result of incorrect ACPI table

Dear R-Help, I am using the function "topTable" from the LIMMA package. To estimate adjusted P-values there are several options (adjust="fdr" , adjust="BH") as shown below: topTable(fit, number = 10, adjust = "BH", fit$Name) I guess any of these options (fdr, BH, etc.) is using a default of FDR=0.05 which is quite conservative (i.e., very

Dear all, I compiled c program with llvm and found something strange with function pointer as following small example . ------------- In C Code -------------- float a (int value) { return value + 1; }; typedef float (*funcptr_t) (int); funcptr_t get_ptr(funcptr_t p) { return p; } float result = get_ptr(a)(4); ------------- In LLVM Code -------------- %4 = call float (i32)* (float

Hello, I have a vector (v) with 6 columns and 2000 rows. I am trying to do one sample t.test for each row (I know this sounds crazy) and put the p.values into the 7th column. I know I can access the p.value via t.test(v[i,])[3]$p.value; I know I can do t.test on the row by apply(v, 1, t.test), but I just couldn't figure out how to fit them together. I'd very appreciate your help!!
