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'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

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

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)

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

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]]

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,

Hello, Apologies if this is a stupid question. I googled and skimmed the archives and didn't see anything specific about this. I am documenting an analysis procedure in a DB and I would like to know the specific version number of each package that I use. Is there a standardized way of getting that information out from R, or should I parse it out from the source-code files? Ideally I

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

Dear all, I want to calculate mean values for multiple rows: structure(list(Name = structure(c(1L, 1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L), .Label = c("AKT", "CKT"), class = "factor"), val1 = c(2, 3, 2, 2, 2, 5, 3, 8, 2), val2. = c(4, 5, 4, 8, 4, 8, 4, 7, 4), val3 = c(5, 6, 5, 9, 5, 9, 5, 9, 5)), .Names = c("Name", "val1", "val2.",

Dear R users, How to change lattice panel label/text from the automatically generated label (based on the conditioning) to our own set of label? for example: someStuff <- data.frame(area = rep(c("SOUTH", "NORTH", "EAST", "WEST"), each = 25), group = rep(c("A","B","C","D"), each = 5),

Dear all, When using latex.table from the quantreg package, I don't seem to be able to set table.env=FALSE: when I don't specify caption (as I think I should, when understanding the R help rightly(?)), I get an error message, and when I do so, of course I get one, as well. The funny thing is, that a table is indeed produced in the first case, so I get a nice tabular, but as I'm using

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

Hi all, I have a data frame with some measured values of some animals. Sometimes the measurement failed, resulting in a NA for a measurement and sometimes the animal died, resulting in NA for all measurements. I have several groups of animals. How do I find the size of each group with only alive animals? And how do I find the size of the groups for each measurement? An example: l1 <-

Hello list, I am wondering if a joining "one-to-many" can be done a little bit easier. I tried merge function but I was not able to do it, so I end up using for and if. Suppose you have a table with locations, each location repeated several times, and some attributes at that location. The second table has the same locations, but only once with a different set of attributes. I would

Hello all, it looks like we have a bug here but I am not sure. Currently if we have two similar types with implicit_const attributes and different values we end up with only one abbrev in .debug_abbrev section. For example consider two structures: S1 with implicit_const attribute ATTR and value VAL1 and S2 with implicit_const ATTR and value VAL2. The .debug_abbrev section will contain only 1

Hi all, I would like to apply a function to each column of an 2-dimensional array, and store the result in a new 1-dimensional vector. I am not sure how to go about doing that syntatically. For instance, can I use lapply? And, if so, how do I specify which dimension should be used? Also, how do I pre-specify the type of object that will go into the 1-dimensional vector. I'm not sure if
