Dear all, I am having troubles importing values written as scientific notation using read.table(). I'm sure this is a frequent problem, as many people in my lab have this problem as well, so I'm sure that I just have troubles googling for the right solution. The problem is, that, given a file like that: a 1 2e-4 b 2 3e-8 ... the third column gets imported as a factor, or a string if I

As an example of the other posters mentioning colClasses, with some debugging notes: # create a pretend file for this example > Lines <- scan(sep="\n", what="") a 1 3e-8 b 2 1e+10 c 3 e-10 d 4 e+3 > file <- textConnection(Lines) # import as you would a file, and specify the column types. > T

Hello, I'm trying to compile vmkit on a x86_64 linux box with gcc-4.1.2, but I'm running into troubles because of various problems with casts between pointers and integers. Is there anybody who succeeded in this task? Az I see, some of the problems can be fixed with an appropriate typedef/macro declaration, but in VMCore/JavaObject.cpp some lowlevel bitmanipulation is used, to mark

Hi Zsombor, Thanks for the patch! Unfortunately I can't apply it because the llvm API has moved from BinaryOperator::create to BinaryOperator::Create. Are you using svn head? Now on the x86_64 part. There has been very little work on porting vmkit on x86_64. If you're having compilation problems, I suppose it's in the garbage collector directory (GCMmap2). If you could make the

Dear R helpers Suppose val1 = c(10, 20, 35, 80, 12) val2 = c(3, 8, 11, 7) I want to select either val1 or val2 depending on value of third quantity val3. val3 assumes either of the values "Monthly" or "Yearly". If val3 = "Monthly", then val = val1 and if val3 = "Yearly", then val = val2. I tried the ifelse statement as ifelse(val3 =

Hello, I am trying to emulate the "stack" as like on x86 when using push/pop so afterwards I can use LLVM's optimizer passes to simplify (reduce junk) the code. The LLVM IR code: define { i32, i32, i32 } @test(i32 %foo, i32 %bar, i32 %sp) { ; push foo (On "stack") %sp_1 = sub i32 %sp, 4 %sp_1_ptr = inttoptr i32 %sp_1 to i32* store i32 %foo, i32* %sp_1_ptr, align

I'm running libvirt 1.0.1 and qemu 1.3.

What is the best way to produce a barplot from my data? I would like the barplot to show each person with the values stacked val1+val2+val3, so there is one bar for each person When I use barplot(data.matrix(realdata)), it shows one bar for each value instead. To post here, I created an artificical data set, but it works fine. fakedata <- as.data.frame(list(LETTERS[1:3])) colnames(fakedata)

Hi, I'm trying to plot stacked barplot with lines on it. Here is the data. emp days val1 val2 score 1 21 1 0 1200 2 35 1 1 na 3 42 na na 3000 4 53 2 1 2100 5 64 1 0 na 6 73 na na 1400 My X-axis is days. I'm looking to plot val1,val2 as stacked bars and score as lines with different y-axis. I could get the bar plot and lines on it but the problem is the bars and lines are not aligning

Thank you for the hint. I adjusted the code and it works: The code after replacing inttoptr with getelementptr: define { i32, i32, i8* } @test(i32 %foo, i32 %bar, i8* %sp) { entry: ; push foo (On "stack") %sp_1 = getelementptr i8, i8* %sp, i32 -4 %sp_1_ptr = bitcast i8* %sp_1 to i32* store i32 %foo, i32* %sp_1_ptr, align 4 ; push bar %sp_2 = getelementptr i8, i8* %sp_1,

Hi, I have data like this.... print(x) ID VAL1 VAL2 1 B A 2 P Q 3 T S What I would like is data like this... ID VAL1 VAL2 1 A B 2 P Q 3 S T So that VAL1 and VAL2 are alphabetically ordered. Any advice is welcome! San. [[alternative HTML version deleted]]

Thanks for the answers. Although I am not sure if I've understood the docs about how inttoptr/ptrtointr are different when compared to gep. It says: "It’s invalid to take a GEP from one object, address into a different separately allocated object, and dereference it.". To go back to my intention why I am doing this, I would like to "emulate" some x86 instructions with

I am trying to find a DVD iso that is not a torrent, and looking through the mirrors I am unable to find one. Does anyone happen to have a mirror or repository that they know of that carries the DVD iso for direct download? I am behind a pretty strict firewall and am unable to do torrents.

Hi again, So I finally gave up on trying to get through the converting (x86' push pop mov add) because it deals a lot with crazy pointer arithmetics and sonce inttoptr and ptrtoint doesn't provide any alias analysis information. Daniel, you said it doesn't make much sense to provide it but in my cases it is actually very much needed, you didn't say it wasn't possible to

Fairly straightforward code motion of MSR / TSC / PMC accessors to the sub-arch level. Note that rdmsr/wrmsr_safe functions are not moved; Linux relies on the fault behavior here in the event that certain MSRs are not supported on hardware, and combining this with a VMI wrapper is overly complicated. The instructions are virtualizable with trap and emulate, not on critical code paths, and only
