Hi all mailing listers, I wanna get the last several elments of vector. e.g. x <- c(1,2,3,.....,78, 79, 80) How can I implement to assign last three elements to y, y <- c(78, 79, 80) ? In Matlab, It can easily achieve by y=x(end-2:end) Thanks Huaping Wan [[alternative HTML version deleted]]

Up to now, the tests have been running with whitespace stripped out. Newlines and tabs are insignificant in HTML, so I figured why bother with them? Now I realize why: they''re significant in pre tags and they also make your code look pretty! I''ve been working to get SRC output to roughly match Tetxile2''s as far as tabs and newlines go. It''s tough and

...e answers to these questions are "Yes". std::vector<const Type*> Elts; Elts.push_back(PointerType::get(StructTy)); Is it possible to build an expression that uses the newly generated Elt as field-selector at this point? I'm hoping yes, but I suspect No, because the elments of Elts* are clearly Type* instead of being a field. In particular, if I use the same type twice to make two fields, the corresponding elements of Elts will be indistinguishable. Elts.push_back(Type::Int32Ty); StructType *NewSTy = StructType::get(Elts); Presumably at this point is is d...

...rame. I need to loop through all rows of the list element 1 AND (if applicable) of the list element 2 etc. and do something at each iteration. I am trying to figure out how to write a code that is generic, i.e., loops through the rows of all elements of my lists even if the total number of the list elments is unknown in advance. Below is an example. a=expand.grid(1:2,1:2) b=expand.grid(1:2,1:2,1:2) ################################################# # My list that can have 1 element, e.g.: l.short<-vector("list",1) l.short[[1]]<-a # I need to loop through rows of l.short[[1]] and do so...

I'm not following; are you trying to access the first member of NewSTy here? You can't use a type th...

Hi folks, here is a short RFC regarding hashing for the implementation of switch statements and my preliminary patch. I posted this patch on 2014-01-16 21:58 at llvm-commits at cs.uiuc.edu. You can find a copy e.g. on http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20140113/201782.html. Best regards Jasper === Preliminary: Special identifiers n number of given switch labels
