Dear All, I'm not sure if I understand the parameter stringsAsFactors correctly. I'm trying to convert the string columns in aframe1 to factors. But it seems stringsAsFactors=T in as.data.frame() doesn't do anything. Could anybody let know what is the correct way to converting strings to factors? > aframe1=data.frame(x=LETTERS[1:10], y=LETTERS[1:10], stringsAsFactors=F) >

Hi, (sorry if the CC's are inappropriate, they seemed relevant based on a git log of IRMover.cpp) I'm using LLVM to implement Just-in-Time compilation for PostgreSQL. One part of that is doing inlining of operators. For that I'm using bitcode pre-generated using clang. The current code uses a single LLVMContext & Orc to generate the code. That largely workes well. But inlining

For the llvm LTO example in the link:http://llvm.org/docs/LinkTimeOptimization.html <http://llvm.org/docs/LinkTimeOptimization.html>, I use below build commands to generate three different optimization level binary: -O0, -O1, -O2.

Hi all, For example,if there is ten subdirectories named sub1~sub10(each including subdirectories and files too),and file1~file10,how can I rsync only sub2 and sub 3 to the target? /---- MyFolder |---------- sub1 |---------- sub2 |---------- sub3 |---------- sub4 |---------- sub5 |---------- sub6 |---------- sub7 |---------- sub8 |---------- sub9

Hi Umesh, Thank you for the suggestion. I can use the "Brute force method " to narrow down the LTO wrong instructions here and there, but I still don't know why these wrong instructions are generated, and how to let Clang LTO don't generate those wrong instructions. I suspect the wrong code is caused by some LTO wrong optimization pass, so I hope to disable all optimizations in

Yes, the arch is just as you said, something like AMD GPU, but Intel GPU don't have separate register file for 'scalar/vector'. In fact my idea of defining the register tuples was borrowed from SIRegisterInfo.td in AMD GPU. But seems that AMD GPU mainly support i32/i64 register type, while Intel GPU also support byte/short register type. So I have to start defining the registers from

Hi there, I'm sure there's an easy answer to this, and I can't wait to see it. The question: is there an easy way to sort a data frame by it's row names? My dilemma: I've had to pull apart a data frame, run it through a loop to do some calculations and generate new variables, and then re-construct the chunks back into a data frame at the end. Doing this preserves the row

I have a population of subjects each with a variable which has been captured at a baseline date. Then for many subjects (but not all) an intervention has occurred and the variable has changed at one or more time points after the baseline date. So my dataset consists of a subject ID (x), which may appear several times or just once, a measure (y), and a date of observation (z). I would like to be

Hi all, According to the documentation ( http://www.voip-info.org/wiki/view/Asterisk+h+extension): Be aware: Macros require their own h extension as they do not make use of the calling context's h extension! Does this apply to subroutines too? I am unable to find the corresponding explanation. If not: what happens when a call is hanged-up during the execution of a subroutine? Is the h

Hi, I used the following commands on the program attached below: llvm-gcc --emit-llvm main.c -c -o main.bc opt -ipconstprop main.bc -o main1.bc diff main.bc main1.bc no difference was o/p :( The Program Segment is as shown below: #include <stdio.h> void f1(int a) { a=a+1; printf("%d",a); } void f2() { int b; b=1; f1(b); } int main() { int

Hi Escha, Great to have your comment! Do you have any specific reason for not doing like this? I am not sure whether I understand your point correctly. For "just model one thread", do you mean "only considering ONE of the 8/16 working lanes that running in lock-step way"?? For my case, may be something like I only need to define r0~r127 as register for i32 register (each r#

I am installing my second server in the datacenter but having problems getting to the net with it. I am going to use it as a KVMvirt host and do not want to run bind on its base OS. My thought was to just refer to it in the bind zones as an additional record (main.example.com is the working server now, main2.example.com is the new one). I cannot get the new one to reach out to the net, is

Hi, I just started with R and I found that there are many options to rearrange the data to do mixed models. I want to use the reshape function. I have 2 between subject variables and one within. I was able to change the data structure but still - the result of the aov functions are calculating everything as a within subject. the table looks like this: SerialNo breed treatment distance_1

Hi, In Splus if I call the function crosstabs() the output is a contigency table; in each cell of the table is printed: N, N/RowTotal, N/ColTotal, N/Total. N is the number of observations in each cell. The same call to xtabs() in R will produce the contigency table but the only entry in each cell is N. How can I get the same relative frequencies that crosstabs() gives? Thanks, mike --
