similar to: using if then statements in a dataframe

I have a data frame with a couple million lines and want to retrieve the largest and second largest values in each row, along with the label of the column these values are in. For example row 1 strongest=-11072 secondstrongest=-11707 strongestantenna=value120 secondstrongantenna=value60 Below is the code I am using and a truncated data.frame. Retrieving the largest value was easy, but I have

Hi all, After writing data in MMF(Memory Map File) using SEXP structure, can i reference in R? If input data is larger than 2GB, Can i reference MMF Data in R? my work environment : R version : 2.11.1 OS : WinXP Pro sp3 Thanks and best regards.

Hi Piotr, I think I found a working matcher: match ifStmt(hasCondition(implicitCastExpr(hasImplicitDestinationType(isInteger()), has(cxxMemberCallExpr(callee(cxxMethodDecl(hasName("compare"))), hasArgument(0, declRefExpr().bind("str2")), callee(memberExpr(has(declRefExpr().bind("str1"))))))))).bind("case1") This one bind to both str1 and str2 in

Hi Piotr, Thanks. Yeah, it seemed a little weird, but it was what got me closest. I found out that the matcher I supplied here was working for clang-query 3.8.1. I'm working on a clang-tidy module for 4.0.0 - it's not working there. Could you elaborate on the "onImplicitObjectArgument"? There is no document on it on the clang page. So I wouldn't know how it works or what it

Hello everyone, I've added the "S" suffixed versions of ARM and Thumb2 instructions to tablegen. Those are, for example, "movs" or "muls". Of course, some instructions have already had their twins, such as add/adds, and I leaved them untouched. Besides, I propose the codegen optimization based on them, which removes the redundant comparison in patterns like orr

but why this code don't work: ; ModuleID = 'sample.lz' @.str1 = internal global [6 x i8] c"world\00" ; <[6 x i8]*> [#uses=1] @.str2 = internal global [7 x i8] c"hello \00" ; <[7 x i8]*> [#uses=1] @.str7 = internal global [7 x i8] c"father\00" ; <[7 x i8]*> [#uses=1] @.str8 = internal global [8 x i8]

I am trying to understand the hello word assember example. This is my version: %str1 = internal constant [13 x sbyte] c"Hello World\0a\00" declare int %printf(sbyte*, ...) implementation ; Functions: int %main() { %str2 = getelementptr [13 x sbyte]* %str1, long 0, long 0 call int(sbyte*, ...) *%printf(sbyte* %str2) ret int 0 } Why is getelementptr being given two "long

Dear developers: When I am doing basicblock pass, I meet a bug: there is an iterator "I" in a basicblock, and it is not pointing to the first instruction in this basicblock. However, "I--;" will fail by an assertion. The basic block ("I" is pointing to the second instruction) in test.ll: bb: ; preds = %bb1 %1 = call i32 (i8*, ...)* @printf(i8* noalias

Dear all, I find some troubles about how to extact the row from csv. file by using if-statement condition. I want to extract the row if the rainfall is greater than the mean of rainfall and using the wrfta divided into 3 groups that's rainfall greater than mean -> group A ( create file group A_rain) -> groupB ( create file group B_rain)

Hi, I am trying to use alias analysis (Anderson) and noticed that for pointers to functions I don't get the expected result: a pointer that clearly may point to a function is reported as NoAlias. I use -anders-aa -aa-eval -print-no-aliases -print-may-aliases -print-must-aliases Here is a test case: ///////////////try_calls_aliases.c #include <stdio.h> typedef int (*PF)(); PF

Dear all, [system and version information below] I am trying to modify a C function for finding the root of an expression.

Hi, I have a vector, which contains both strings and numbers, e.g. > foo <- c("str1",1234,"str2",0.9876) I want to know if a distinct element of the vector is a string or a number and took "is.numeric", but > is.numeric(foo[2]) [1] FALSE because R treats the numbers in a mixed vectors as strings: > foo [1] "str1" "1234"

Dear List, i am trying to produce a 3d plot using wireframe using the code: wireframe(Residuals_FD ~ Elevation * Temperature, data = data2, scales = list(arrows = FALSE), drape = TRUE, colorkey = TRUE) As you can see when the code (using the data below) is run the plot area is set-up correctly but the actual surface is missing? Any help would be greatly appreciated. Chris #data Elevation

I have some elements in a vector with extraneous information (e.g. file name and sample IDs) that I'd like to strip from every element. For example, I would like "SPI1.S1.str1.P3.sample.tif" "SPI1.S1.STR2.P1.sample.tif" to read "SPI1.S1.str1.P3" "SPI1.S1.STR2.P1". Will someone help me with the syntax in gsub? It needs to be something like

Hi, Hope this is the right channel for this question. I am trying to make an ast matcher for clang-tidy to find str1.compare(str2), where both str1 and str2 are std::string. I have this so far: http://i.imgur.com/sUma9WC.png . But I am having a hard time finding a way to bind an id to the str1 part of the expression. Can anyone help me out with an idea?
