similar to: C function with unknown output length

Hello. I'm trying to read a delimited file. I'm a little new to the R api. In the program, I do something like this... /*****************************/ SEXP retval; PROTECT(retval = allocMatrix(STRSXP,1,names.dim)); int r_eltctr = 0; while(!myfile.eof()) { SET_LENGTH(retval,r_eltctr+num_of_fields); for(int i = 0;numofcolumns; ++i) { INTEGER(retval)[r_eltctr++] = 1;/*some

Hi folks. I posted this question a few days ago, but maybe it got lost because of the code I included with it. I'm having a problem using the SET_LENGTH() macro in an R extension I'm writing in C++. In a function within the extension I use SET_LENGTH() to resize R vectors so as to allow the concatenation of single values onto the vectors -- it's a "push back" function to

Hello all, thanks for all the help on the other issues. This one should be relatively straightforward. I have a vector of integers which I allocate to be the maximal size possible (meaning I'll never see more than cel.GetNumOutliers, but most likely I'll see less) therefore, I want to resize the vector, one solution would be to allocate a new vector then to copy into the new vector. That

Dear R Gurus, I would very much appreciate some help with this code snippit from my RODBC package. R crashes or exhibits bizarre behaviour when repeatedly fetching large numbers of rows. Examples: > odbcFetchRows(0,max=50000)->xx > odbcFetchRows(0,max=50000)->xx > odbcFetchRows(0,max=50000)->xx > odbcFetchRows(0,max=50000)->xx > odbcFetchRows(0,max=50000)->xx 3rd

Hi all, I found that the figure returned by MSet::get_matches_estimated() varies depending on how results are to be sorted. For instance, in my index, value 4 contains date and time in the format "yyyymmddhhmmss". For the same query, the number of results will be estimated to 20000+ when results are first sorted by date and time with set_sort_by_value_then_relevance(4) and to only 100

Hi, Is there a way to resize a matrix defined as follows: SEXP a = PROTECT(allocMatrix(INTSXP, 10, 2)); int *pa = INTEGER(a) To row = 5 and col = 1 or do I have to allocate a second matrix "b" with pointer *pb and do a "for" loop to transfer the value of a to b? Thank you Best regards Morgan [[alternative HTML version deleted]]

Hugh, (Note I speak for myself only and not for R-core) Thanks for looking into this. I think it's great to have community members that are interested in contributing to R and helping it continue to get better. And I think, and my local experiments bear out, that using anyNA as a fastpass condition does allow us to get a significant speedup over what's in there now. To do so, though, I

Xapians! Did anybody wrote and would like to share a routines that parse result from doc.get_data() into some key and pair values in C++ ? Code: Xapian::Document doc = i.get_document(); string data = doc.get_data(); mymap = parse_result(data); As you know the data string contain all the data within the document delimited by "=" sign and "\n" new line and needs to be parse

For regular expression afficianados, I'd like a cleverer solution to the following problem (my solution works just fine for my needs; I'm just trying to improve my regex skills): Given the string (entered, say, at a readline prompt): "1 2 -5, 3- 6 4 8 5-7 10" ## only integers will be entered parse it to produce the numeric vector: c(1, 2, 3, 4, 5, 3, 4, 5, 6, 8, 5, 6,

Hi listers, A few days ago I posted a question about the use of the stars function on selected lines of a frame. Thanks to two helpers, a closer look at the scale argument allowed to partially solve the problem. Yet I still have a problem with stars. Allow me to explain what I intend to do (sorry for my poor English and the long post): I want to graph an activity index of a fish during the day

This is a feature (or bug) of MCSectionELF::PrintSwitchToSection. For ELF target this function tries to escape string if it founds 'suspicious' character, see implementation in MCSectionELF.cpp: StringRef name = getSectionName(); if (name.find_first_not_of("0123456789_." "abcdefghijklmnopqrstuvwxyz"

Create the ref_bo without any storage type flags set for now. This can probably be split up somehow later on, but this seems to work. Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> Cc: "10.0" <mesa-stable at lists.freedesktop.org> --- Would be great if someone could see if this also makes MPEG4 work on NVA3+. In order to do that, remove the if (chipset < 0xc0)

So, when performing expression evaluation, lldb trips over an assert in clang/lib/AST/RecordLayoutBuilder because ExternalFieldOffsets doesn't contain a FieldDecl that updateExternalFieldOffset expected. I found that the assert occurs when both static and non-static member variables are present. For instance, with the following, the lldb command 'expr my_test.length()' does not

The documentation for the sanitizer special case list format[0] says, > The meanining of * in regular expression for entity names is different - it is treated as in shell wildcarding. In SpecialCaseList::parse, we see that this is just replacing * with .*: // Replace * with .* for (size_t pos = 0; (pos = Regexp.find("*", pos)) != std::string::npos; pos +=
