similar to: 2D array of strings

Hi all, I'm trying to learn R after years of Matlab's experience. Here is an issue I couldn't solve today. Consider the following piece of code (written by memory): for(i in 1:n){ submat <- data[1:i,] C <- colSums(submat) } The problem is that at the first iteration, data[1:1,] reduces to a vector and colSums returns an error. This sounds really strange to me

Hi I am searching for a way to do something like "ABC" -> c("A","B","C"). How can this be accomplished? I tried cut() and split(), but they do something else, it seems. The purpose for doing this is to find the number of common (and uncommon) characters, i.e. ultimately I want something like this: > foo("ABD","ADE") c(2,1) # 2

I read in a CSV file with Data <- read.csv(file="FileName.csv",head=TRUE,sep=",") the file containts strings in the 2nd and 3rd columns and each has about 1000 rows. I need to either loop through the strings there looking for strings that would trigger other logic or remove those rows and put them in another array and loop through them in the new array. I can't seem

Can someone tell me which version of R began to order alpha-numeric strings in this manner: "ABC 10" < "ABC 2" rather than "ABC 2" < "ABC 10" ? And, is there a way to force "ABC 2" to be ordered as a value less than "ABC 10"? thank you, Karen kschlauc at vt.edu

Hi, I am new in R, i have a matrix like this MyMatrix <- *ABC PQR XYZ* 10 20 30 40 50 60 70 80 90 And, i have an array containing some conditions like this, MyArray <- c("*ABC*>50","*PQR*<50","*ABC*<30 &* XYZ*<40") "ABC>50" "PQR<50" "ABC<30 & XYZ<40"

Given vectors of strings of arbitrary length content <- c("abc", "def") searchset <- c("a", "abc", "abcdef", "d", "def", "defghi") Is it possible to determine the content String set that matches the searchset in the sense of 'startswith' ? This would be a vector of all strings in content that start with

As discussed in the thread on validating $TERM, it would be good to have a common function to do this. This is such a function. The main advantage is it includes unit tests which the previous functions did not. Rich.

"Does that help?" No. I am not your private consultant. You need to reply to the list, which I have cc'ed here, not just me. I am still somewhat confused by your specifications, but others may not be. Part of my confusion stems from your failure to provide a reproducible example (see e.g. the posting guide linked below). For example, I cannot tell from your text whether the Abc

dear all, I have some very long strings and would like to break up each long string into multiple strings with a fixed length, e.g. to break up abcdefghijkl into abc, def, ghi, jkl I tried a couple of commands but was not successful. Any help will be appreciated. Best, Jimmy -- View this message in context:

R Help Forum Is there a R library (or a way) that I can extract unique character strings, or repeating patterns in textual strings. Say for example I have the following records: Abc_1234_kjhksh_276 Abc Abc_1234_lakdofyo_324 Bce_876_skdhk_*&^%*& Bce Bce_454 And I would like to see the following results Abc Abc_1234 Bce Jeff Reichman [[alternative HTML version

### I got bit again by the same bugs I wrote about a year ago. ### The bugs are related to matrices and arrays of lists. ### 1.

Hi, Currently libvirt supports metadata in the domain XML. This is very convenient for data related to the VM, but it is a little awkward for devices. Let's pretend I want to have extradata (say, a specific port for a virtual switch) related to a device (say, a NIC). Nowadays I can store that data in the metadata section, but I need some kind of mapping to correlate this piece of information

Hi guys, I am trying to write a function that allows me to perform specific transformations to each element of a 2 by 2 matrix to generate a 3 by 3 matrix. Input into function-2 by 2 matrix Output from function -3 by 3 matrix For example: # a is my original 2 by 2 matrix #b is my new 3 by 3 matrix set.seed(2) a=matrix(rnorm(4),ncol=2) #let's say these are the transformations i wish to

Dear R listers, I am trying to produce a simple (for a stata user) barplot with 4 countries on the x axis, each country observed in 2 subsequent years and 3 variables. Basically, I should have three bars for each year for each country. I am attaching the chart I made in Stata, but I am not sure you'll manage to see it! I did the following: #here I create the data-set TUSE2. The vectors mw, st

I have an S-Plus library that I would like to port to R. The library sends a mix of static and dynamic output to an html file. For example cat(" ... Big block of HTML formatting code ... ") cat(dat()) cat(" More static text ") With S-Plus I can just cut and paste HTML code from other files into my S-Plus script file. This makes maintenance of the script fairly easy. The
