Dear list, I am trying to create a folder structure, say 'test/sub', and set the folder and sub folder to be writable to everyone. By default dir.create('test/sub', recursive=TRUE, mode='0777') creates folders with mode: drwxr-xr-x After Sys.chmod('test/sub',mode='0777') The folder 'test' is: drwxr-xr-x and the sub folder 'sub' is:

Hi Chijun, Thanks for your interest in the project.

I have also started to understand the algorithm mentioned in > the comments of the code related to the

Hi Kuba, Thanks for your advice in your previous letter. During last week, I have read the documents on Doxygen and the source code of the DomTreeBase/DomTree/PostDomTree/DeferredDominance class, I believe now I have a much better understanding on the relationship between these classes and how DeferredDominance class performs lazy updates. I have also learnt the current usage and drawbacks of

Hi Kuba, Thanks for your clarification on the project in the previous letter. I have submitted a proposal draft at the GSoC website, the draft has been shared with the LLVM organization. I will appreciate it if you can give me some advice on the proposal. This draft can be viewed by the organization. (If you do not have access, please mail me, and I will give you the link.) I am looking forward

Hi Chijun, Great, seems like you did a lot of progress and understand the issues quite well! I have done some early sketch on the API of the new updater class. > From my current understanding, to solve the fragmentation problem of > the API, the new class first, need to maintain the DomTree and > PostDomTree class and deprecate the DefferredDominance class. > There are a couple of

Hi Chijun, I left you my feedback in the doc (+ some nitpicks). Overall, it looks very solid and shows you understand the problem well and know what to expect. Your proposed timeline is reasonable and I don't see any major things to improve there. Don't hesitate to reach out if you have any questions related to my comments (either here or in the document). Thanks, Kuba On Wed, Mar 21,

Hi Kuba, Thanks for your feedback. I have made some improvements on the proposal according to your feedback and clarify something on the time availability. I left comments on the questions you asked in the doc. Please check it out.

suppose x is a matrix. how to define ||x|| in R? thank you! --------------------------------- [[alternative HTML version deleted]]

suppose I have a function example: getMatrix <- function(a,b){ A1<-diag(1,2,2) } If I want to get the both the A1 and dim(A1) from the function, Can I do return(A1,dim(A1)) inside the function ? And how can I access A1 and dim(A1) later on? --------------------------------- [[alternative HTML version deleted]]

I was trying to plot date time vs numeric values. Number of My date value are about 4000, It is continuous time series, 3 days, the interveal is 5 minutes, (2002-09-22 12:35:00 pm to 2002-09-22 3:40:00 pm) How can i plot it in R? I tried the regular way: formattime <- strptime(time, format= "%d-%b-%y %I:%M %p") plot(formattime, outNum) However the x axes doen't give me the

About six months ago there was a reference to a site (in french) that did a spectacular job of demonstrating R's graphical capabilities. My bookmarks were recently wiped and I cannot find this site despite my best googling. Anyone have the address which I have done a miserable job describing? Thanks. Michaell

Hi, I am clustering data based on three numeric variables. I have a fourth variable that is categorical (site) which I would like to use to label the leaves of my dendrogram, so I can see how the different sites are grouped throughout the tree, but I do NOT want to use this variable in the cluster analysis itself. Is there any way I can do this? Thanks, Samantha -- View this message in
