Newbie - Summarize function
Dear R Users, I have searched through the archives but I am still struggling to find a way to process the below dataset. I have a dataset that has stratum and plot identifier. Within each plot there is variable (Top) stating the number of measurments that should be used to to calculate the mean to the largest "top" elements within one of the vectors (X). I would like to process

Parallel assignments and goto
Following up on this attempt of implementing the tail-recursion optimisation ? now that I?ve finally had the chance to look at it again ? I find that non-local return implemented with callCC doesn?t actually incur much overhead once I do it more sensibly. I haven?t found a good way to handle parallel assignments that isn?t vastly slower than simply introducing extra variables, so I am going with

Parallel assignments and goto
Interestingly, the <<- operator is also a lot faster than using a namespace explicitly, and only slightly slower than using <- with local variables, see below. But, surely, both must at some point insert values in a given environment ? either the local one, for <-, or an enclosing one, for <<- ? so I guess I am asking if there is a more low-level assignment operation I can get my

Parallel assignments and goto
Hi guys, I am working on some code for automatically translating recursive functions into looping functions to implemented tail-recursion optimisations. See https://github.com/mailund/tailr As a toy-example, consider the factorial function factorial <- function(n, acc = 1) { if (n <= 1) acc else factorial(n - 1, acc * n) } I can automatically translate this into

control of scat1d tick color in plot.Predict?
Hi All, I have a quick question about using plot.Predict now that the rms package uses lattice. I'd like to add tick marks along the regression line, which is given by data=llist(variablename) in the plot call. The ticks show up fine, but I'd like to alter the color. I know the ticks are produced by scat1d, but after spending a fair bit of time going through documentation, it still

[LLVMdev] poolallocation error
Hi, I am trying to use the poolallocator. More specific, I am trying to play around with the pointer compression pass. Though, I get assertion failures for the pass dependencies. This is when it in PointerCompress::getAnalysisUsage tries to register the the BU pass as required. I.e. when AU.addRequired<CompleteBUDataStructures>(); is called. $ opt -f -load

Creating a global variable for a struct array

Creating a global variable for a struct array
Thank you very much. The code to initialize h1 to non-zero values was what I was looking for. It's almost working except for a type mismatch wrt dlist* llist field of h1. dlist static_lst[10] = { {1, 5, NULL}, ... }; dhash h1[10] = {{"myfile.txt", static_lst}, ... }; Along the lines of the code you had sent, I created a GlobalVariable* llist of type [10 x %struct.dlist]* for the

[LLVMdev] poolallocation error
Dear Prakash, Yes, DSA is still in active use, although nobody else uses the -ds-aa pass as far as I know. I tried the below sample (although ds-aa should be in libLLVMDataStructure.so and not libpoolalloc.so), and I get the same error. I've seen similar problems with other passes in our work here. My guess is that -ds-aa is requiring two passes that claim to invalidate each other; this
