similar to: searching several subsequences in a single string sequence

Is there a function to efficiently search for a subsequence within a vector? For example, with x <- 1:100 I'd like to search for the sequence c(49,50,51), and be told that it occurs exactly once, starting at location 49. (The items in the vectors might be numeric or character, and there might be repetitions within the search pattern or within the vector I'm searching.) Duncan

Hi all, I've come across a very strange bug with Xapian 1.0.9.0 and the Turkish query parser when trying to index a string (as posting) that looks like this: "...bir araya getiren CD'leri son teknolojiyle piyasaya...". The actual offending bit of the string is: 'leri It throws the message I have shown below. The real annoyance is that I can't seem to catch it because it

Hi, I would like to generate a list of all subsequence of length k from an array with length n (k < n). The result should be organized in a matrix. So the matrix should look like the following whereas each row is one of a subsequence of len k. [a[1:k], a[2:(k+1)] a[3:(k+2)] ... a[(n-k+1):n] Is there away to do this with sapply method? thanks, Ron

Hi List! I have an issue with dovecot: Outlook express users sometimes can't see some emails (they are not even listed) that can be seen with other IMAP clients, I tested it (and it works) with Evolution, Outlook and SquirrelMail (a web mail). Please note that this is not the client bug reported at http://dovecot.org/clients.html with the message: "Message is no longer available on

Hello, I'm having a litle issue with Xapian-1.0.6 with php bindings under php5 when trying to add a new document it throws: Fatal error: Uncaught exception 'Exception' with message 'DatabaseCorruptError: Failed to unlink /var/lib/xapian/trade.ar/termlist.baseA: No such file or directory' in /usr/share/php5/xapian.php:1140 Stack trace: #0 /usr/share/php5/xapian.php(1140):

Hello together, I'm looking for advice on how to do some tests on strings. What I want to do is the following: (just an example, real strings/sequence are about 200-400 characters long) given set of Strings: String1 abcdefgh String2 bcdefgop use a sliding window of size x to create an vector of all subsequences of size x found in the set (order matters! ). Now create, for every string

Hi, R-users, I have a problem: Because there are few files which can't be readed into R completely, so on the following subsequence programme, I use write.table, which creates the "NA" files for those incomplete files autimatically. I don't want those NA files. My programes formats looks like: name_c<-Sys.glob("C:/Documents and Settings/lma/My

Hallo, suppose I have a vector: x <- c(1,1,1,2,2,3,3,3,3,3,4) How can I generate a vector/sequence in which a fixed number of zeroes (say 3) is inserted between the consecutive values, so I get 1,1,1,0,0,0,2,2,0,0,0,3,3,3,3,3,0,0,0,4 thanks a lot, Serguei [[alternative HTML version deleted]]

Is there an R analog of the Unix command uniq -c: http://en.wikipedia.org/wiki/Uniq Given an array x, uniq -c replaces each contiguous subsequence of identical numbers with a tuple (count, number). E.g. $ cat > usample 10 10 9 8 8 7 7 7 6 3 1 1 1 0 $ uniq -c usample 2 10 1 9 2 8 3 7 1 6 1 3 3 1 1 0 Cheers, Alexy

Dear R users, The TraMineR package for mining, describing and visualizing sequences of states or events, and more generally discrete sequential data has been updated to version 1.2. Its primary aim is the analysis of biographical longitudinal data in the social sciences, such as data describing careers or family trajectories. Most of its features apply however also to non temporal data such

Hi Nicolas, I plan on using the Avian GC (which is a precise, generational collector). Eventually, I'd like to fully integrate all of the runtime services Avian provides - even integrating the existing Avian JIT compiler, to allow for partially-AOT builds. Avian does indeed have it's own class library, but I would be very surprised if VMKit could compile with them - they are sufficiently

Hi all, When I run the example in RProfmem, I get: Rprofmem("Rprofmem.out", threshold=1000) example(glm) Rprofmem(NULL) noquote(readLines("Rprofmem.out", n=5)) ... [1] 1384 :5416 :5416 :1064 :1064 :"readRDS" "index.search" "example" [2] 1064 :"readRDS" "index.search" "example" [3] 4712

Hi Minas, Thanks! I wasn't aware that VMKit had the ability to generate llvm code from .class / .jar files - I thought all of its code-generation capabilities were very closely tied to the VM itself. I'll look into this. The motivation behind this project is to be able to get both the small size and fast startup times of Avian, along with the speed of llvm-generated code. Currently,

Dear Listmembers, wanting to learn more about ALTREP I wrote the following function to extract a subsequence from an integer vector: #include <Rinternals.h> SEXP integer_get_region(SEXP _x, SEXP _i, SEXP _n) { int i = INTEGER(_i)[0]; int n = INTEGER(_n)[0]; SEXP result = PROTECT(Rf_allocVector(INTSXP, n)); INTEGER_GET_REGION(_x, i, n, INTEGER(result)); UNPROTECT(1); return

Hi Joshua, What plans did you have for GC? No GC at all or Avian JVM has its own GC (and is it precise or not?)? If you're not planning on using VMKit's GCs, then 64-bit system should not be a big problem: the only problem that we have now is compiling GNU Classpath, and most probably Avian JVM has its own version of the class libraries? Also, note that platform support will be strongly

Hi, I'm trying to use the Java front-end (which, based on svn commits, appears to be three-years-dead), and I'm running into some build errors. In that time did llvm change from building with exception handling and rtti to building without? I remember reading somewhere that llvm code should use dyn_cast instead of dynamic_cast. Do these need to be changed here? A little background:
