Hi all, I wonder if there is a way to create a matrix with two (or even more) column/row names? Thank you very much. Have a nice day. -- ??? Hesen Peng http://hesen.peng.googlepages.com/

Does anyone know what is the complexity of the "mem2erg" optimization on llvm ir? Is it linear or quadratic? Regards, -Peng -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20150817/c3b210f1/attachment.html>

...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

I tried several functions in nlme, but I cannot find a correct one.

...unning my R program on some servers for a while but do not know exactly how R is working. The servers are chained together using Sun Grid Engine. Each node has 8 quad-core CPUs. I wonder how many cores and CPUs are used by a simple single-thread R program. Thanks a lot. Best wishes, -- ??? Hesen Peng http://hesen.peng.googlepages.com/

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'm learning the tutorial. http://llvm.org/docs/tutorial/ I'm wondering if there is already a git repository of the examples in the tutorial so that I don't have to copy the code from the webpage. Thanks! -- Regards, Peng

...number of lines for group 1) a11 a12 a13 a21 a22 a23 ... B(number of lines for group 2) b11 b12 b13 b21 b22 b23 ... I guess SAS may work pretty well in this kind of situation with data step. But I don't know how to handle them using R. Any suggestions? Thanks a lot. Best wishes, -- ??? Hesen Peng http://hesen.peng.googlepages.com/
