Hi, I am wondering if some experienced users would help put the ready-to-run code of the examples in the manuals. It would help new users learn R faster by putting all the examples in an ready-to-run R script file. Can somebody help do so sometime and post the code along with the pdf manuals? http://cran.r-project.org/manuals.html Regards, Peng

Hi, x=matrix(1:60,nr=6) I can refer the last 2 rows by x[5:6,] If I don't know the total number of rows is 6, is there a way to refer the last 2 rows? Regards, Peng

I am wondering if there is a function that can return an indicator for any element whether it appears in a vector twice or more. Regards, Peng

Hi, I'm wondering if R provide a vi mode in the command line just like other shells such as bash do. Can somebody let me know? Regards, Peng

Hi, I don't quite understand what are the return values of aov. I know that it has 'coefficients'. But I need to know what all the other return values are. Can somebody let me know how to figure them? Value: An object of class 'c("aov", "lm")' or for multiple responses of class 'c("maov", "aov", "mlm",

I did a sanity check and run some of the bitcode I complied with gllvm and it seems to work fine under lli. The only issues is to make sure you load all the (external) libraries the bitcode needs. I highly suggest you run a debug version of lli under a debugger and see what exactly happens. On Mon, Jan 28, 2019 at 12:45 PM Peng Yu <pengyu.ut at gmail.com> wrote: > It seems that it does

Hi, I can use the following code to generate a matrix, each column of which is 'x'. But I have to specify '5' twice in the second command. I am wondering if there is a better way to do it. > x=1:10 > matrix(rep(x,5),nc=5) > t(matrix(rep(x,5),nc=5)) Regards, Peng

Hi, I am wondering how to pop up the graphics window from Rscript. I run the following code, but I don't see the graphics window, even transiently. Regards, Peng $ Rscript plot.R > x=1:10 > y=1:10 > plot(x,y) >

Hi, I am wonder if there is a function similar 'apply' but it could accept multiple arguments? For example, I have the following matrix. x=matrix(1:6,nr=2) y=matrix(1:6,nr=2) I want to find a function that can be used to compute the linear regression for each pair of rows in the two matrices? multiple_apply(x,y,1,function(u,v){lm(u ~ v)} That is, I wound like something like the above

Hello Peng Yu, I found the same error on my Macbook Air. This was my first trying on MacOS X. Troubleshooting this might take sometime. Only thing I can say now that klang is tested successfully on Ubuntu with - LLVM 3.2 official release on LLVM download page - LLVM svn latest update Clang compile produces an error message on MacOS X with the LLVM svn latest update I am trying to find the

Hi, I have llvm installed through MacPorts. But I don't see macports installed. Are there supposed to be manpages of commands like lli installed? -- Regards, Peng

Some examples in the help page are too long to be copied from screen. Could somebody let me know some easy way on how to extract the example to a file so that I can play with them?

Hello Peng Yu and List, I have put toy.cpp into github but it has a form of LLVM project makefile infrastructure. So you can build it together with LLVM Project source tree. git://github.com/Journeyer/klang.git There exist many branches and each branch is for each chapter of Kaleidoscope.

This works great. > You can also try using the gllvm wrapper: https://github.com/SRI-CSL/gllvm ; it's quite reliable and easy to use in my experience. Just to be sure. Only one version of bc file will be generated that corresponds to the compiler options provide at configure? The original approach using ld.gold will provide several .bc files that correspond to different stages of the
