Hello all, For some work I am doing on RNA, I want to use R to do string parsing that (I think) is like a simplistic HTML parsing. For example, let's say we have the following two variables: Seq <- "GCCTCGATAGCTCAGTTGGGAGAGCGTACGACTGAAGATCGTAAGGtCACCAGTTCGATCCTGGTTCGGGGCA" Str <-

I shouldn't try to do this on Monday morning. Can anyone suggest why the make for R 0.63 is failing for me under Solaris (SunOS 5.6).

I would like to do some fairly basic stem-and-leaf displays in R. I am aware (I might even say painfully aware) of stem(base) and have tried it. That's why I'm hoping someone has a usable stem- and-leaf display for R so that I don't have to write my own. r-project.org > Search > R Site Search > "stem and leaf display" finds nothing. I also tried the mail archive

Is the following a bug with stem() or is there something else that I am missing? I ran stem() on the vector x below and got stem(x-10) instead of stem(x). If I subtract 1 from x, I get a correct answer. If I add 1 to x, I still get a wrong answer. If I add 10 to x, I get a correct answer. I'm not sure what to make of this, other than to think it is a bug. Can anyone tell me if this is a bug?

A version using regular expressions, regexpr() and substr() functions is attached. Finally everything is packed into splitSeq() function (chunk 14 in the attached file) Seq<- "GCCTCGATAGCTCAGTTGGGAGAGCGTACGACTGAAGATCGTAAGGtCACCAGTTCGATCCTGGTTCGGGGCA" Str<-

Hello R-philes: I have the following function that gets the output of mget() and converts it to a data frame to return. What I am finding is that the dimensions are wrong. Basically, I get: bridesmaid wed u see m gt lt like love X.0 dress pagetrack one go X3 get 1 56 35 27 30 24 20 20 23 28 17 25 16 16 28 15 26 Instead, I want something like: [1] bridesmaid

Hi All I came across a problem below when doing stemming and stem completion with package tm in R. Word "mining" was stemmed to "mine" with stemDocument(), and then completed to "miners"with stemCompletion(). However, I prefer to keep "mining" intact. For stemCompletion(), the default type of completion is "p...

Does anyone know if xapian stemming support suffix -er? I tried -s and -ing both work, but not -er. _________________________________________________________________ ?????????????? MSN Messenger: http://messenger.msn.com/cn

I am developping a personal/desktop search tool for which I am experimenting with doing no stemming during the indexing, but instead having a stem database (or several for different languages), used for expanding the query terms at search time. (ie: user query: flooring -> stem: floor -> final query for: [floored flooring floorings floors]) I have thought of a possible problem with w...

Hello, I have a data set that needs to be combined so that rows are summed by a group based on a certain variable. I'm pretty sure rowsum() or rowsums() can do this but it's difficult for me to figure out how it will work for my data based on the examples I've read. My data are structured like this: Plot SizeClass Stems 12 Class3 1 12 Class4

Let's try x<-matrix(1,nrow=100,ncol=1) stem(x) Then you will get infinit flow. The decimal point is 9 digit(s) to the left of the | -214748360 | -214748358 | -214748356 | -214748354 |

Hi, I would like to make a stem and leaf plot and I want to edit the category-names. So, by doing this: > x <- c(1,2,2,3,3,3,3,2,2,1) > stem(x) I get: 1 | 00 1 | 2 | 0000 2 | 3 | 0000 First Question: Why do I get gaps between the categories? (like in line 2 and line 4) And second: How can I edit the categories so that I can create something like that:

Hi all, I am trying to implement a search that will use the Stem Analyzer. I added the Stem Anaylzer from the examples shown in another post http://ruby-forum.com/topic/80178#147014 module Ferret::Analysis class StemmingAnalyzer def token_stream(field, text) StemFilter.new(StandardTokenizer.new(text)) end end end The problem with the Stem analyzer is that when I search for a term such as ''engineering'', it only matches whole words that fit the stem so the only results I get back ar...

Referring to "Using R for Data Analysis and Graphics" by J H Maindonald, and available from the R site, I found the example on p.30 non-working: > stem(qqnorm(possum$hdlngth)) Error in stem(qqnorm(possum$hdlngth)) : 'x' must be numeric Since qqnorm(possum$hdlngth) plots, and > class(possum$hdlngth) [1] "numeric" , the problem must be here: >

Hi there, I am trying to find a way to accomplish parallel stem-and-leaf displays in R, yet there seems to be no specific command nor info in the archive that I can depend on. Specifically, there are two batches of data that I want to put together in parallel stem-and-leaf displays. Would anyone help me figure out how to do this in R? Thank you sooooooooooooo much!

Hey guys Hi :) I've implemented a PaiceHusk stemmer externally So what I am doing right now is passing a pointer to my StemPaiceHusk class(which in turn has been subclassed from Stemimplementation) to the Stem::Stem(StemImplementation *p) constructor .So basically,I have to include "paicehusk.h" in my indexer .However,I now want to make it a part of the Xapian library so that I

Hi, I need to modify the stemming for a couple of words (a blacklist) and for all the other to use the usual snowball stemmer. The "natural" way of doing it would be to derive from Stem and override operator ()... but I am using *python-bindings*. Would this be possible? If not I have two other solutions in mind: -...

I must apologize in advance for asking a simple question. I am sure that a clue will be sufficient to get this show on the road. I am trying to graph tide prediction data in various ways.
