similar to: ordering of alphanumeric strings

I am running R version 1.7.1 on 3 different operating systems: Linux RedHat, Linux Slackware, and Windows 2000. R is ordering alpha-numeric character strings in different ways, dependent on the operating system. R orders strings exactly the same on Slackware and Windows, and this ordering corresponds to SPlus. It's the RedHat that is creating the problem. On Slackware, Windows, and SPlus:

Dear R helpers Suppose I have a data.frame as given below - my_dat = data.frame(class = c("XYZ", "XYZ", "XYZ", "XYZ", "XYZ","ABC", "ABC", "ABC", "ABC", "ABC" ),  var1 = c(20, 14, 89, 81, 17, 44, 36, 41, 11, 36), var2 = c(1001, 250, 456, 740, 380, 641, 111, 209, 830, 920)) > my_dat    class

Hi, I have a data frame with one column containing string of the form "ABC...|XYZ..." where ABC etc are fields of 6 alphanumeric characters each and XYZ etc are fields of 8 alphanumeric characters each; "|" is a mandatory separator; I do not know in advance how many fields of each kind will each row contain. I need to extract these fields from the string. === How do I do that?

Hi again, I wanted to check in and see if you got my note about the broken link on your site. Thanks!

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

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

I have a bunch of tables in a Microsoft Access database. An updated database is sent to me every week containing a new table. I know that is inefficient and weird but welcome to my life. I want to read the tables whose names are something such as "040207" but not the ones that have alphanumeric names such as "everyone". Using RODBC I am easily able to create a character vector

"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

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.

Sorry for the dumb question, but I couldn't figure this out myself. Consider the following: > str <- c("abc","def") > array(str, c(2,1)) [,1] [1,] "abc" [2,] "def" How can i obtain the outcome of the second instruction without specifying the number of rows? Thank you in advance, Francesco.

Dear helpRs Does anyone have an elegant way of doing the following: For a given numeric vector, e.g. vec <- c(3,2,6,4,7) Create a series of vectors where all but 1 of the values are replaced by 0's, e.g. vec.a <- c(3,0,0,0,0) vec.b <- c(0,2,0,0,0) vec.c <- c(0,0,6,0,0) vec.d <- c(0,0,0,4,0) vec.e <- c(0,0,0,0,7) I have looked at `replace', but can't think of a

I am seeking information on whether anyone has written code to perform Horn's parallel analysis (a procedure that informs the selection of the proper number of components in PCA) in R. Thank you in advance for any help you can provide. Please respond off-list at the email address below.

Have you tried in smb.conf username map = /usr/local/samba/lib/domainuser.map winbind use default domain = no For every user you have to create an entry in the /usr/local/samba/lib/domainuser.map, that looks like <unixusername> = "<domainname>+<username>" I?m using a script that generates the domainuser.map automaticly, because our users are using NIS

Dear R list Would anyone be able to tell me whether it is possible to do "enhanced multidimensional scaling" (enhanced MDS) in R? In other words, something that goes beyond "cmdscale" by iteratively improving the fit between observed dissimilarities and inter-object distances, using the KYST algorithm (Kruskal, 1964). I have found several implementations of non-metric MDS

Hi again Sorry, in looking again at sammon and isoMDS I see that they seem to do exactly what I want, except that they are non-metric, which means, as I understand it, that they relate the rank orders of the variables rather than the actual distances. Could I use these non-metric MDS packages even if my distances are metric? Thanks Karen -- Karen Kotschy Centre for Water in the Environment

Dear R helpers, I have a data.frame as given below - dat1 = data.frame(date = as.Date(c("3/30/12","3/29/12","3/28/12","3/27/12","3/26/12", "3/23/12","3/22/12","3/21/12","3/20/12", "3/30/12","3/29/12","3/28/12","3/27/12",

I was troubleshooting a problem we were having with some files not rsyncing properly over an nfs mount (the destination device is a snapserver (NAS) that did not have native ability to receive streaming rsync info, that's why we were doing this rsync over an NFS connection to the snapserver). Anyway, at first I thought this was just one of the quirks of the snapserver (it isn't

Dear All I'm trying to sort a matrix using function order, Some thing really odd: e.g. abc<-cbind(c(1,6,2),c(2,5,3),c(3,2,1))## matrix I want to sort if I do abc[ order(abc[,3]), increasing = TRUE] the result is correct [,1] [,2] [,3] [1,] 2 3 1 [2,] 6 5 2 [3,] 1 2 3 But if I want to sort in decresing order: abc[ order(abc[,3]), decreasing = TRUE] the
