Hey, I'm using rsync to backup my server but there is a problem because rsync is using very huge amounts traffic. But first to the setup. The server I backup has 4GB of data and I use the following command to backup this data. /usr/bin/rsync -aze 'ssh -i /root/.ssh/backup.key -l backupuser' --rsync-path='sudo rsync' --delete --exclude-from=ex.list $SRC $TRG The problem is

Hello; I am a R newbie and would like to know correct and efficient method for doing string replacement. I have a large data set, where I want to replace character "M", "b", and "K" (currency in Million, Billion and K) to millions. That is 209.7B with (209.7 * 10e6) and 100.00K with (100.00 *1/100) and etc.. d <- c("120.0M", "11.01m",

Hi, I'm try to collect a list of methods/packages available in R for doing in-string variable/symbol substitution, e.g. someFcn("pi=${pi}"), anotherFcn("pi=@pi@") and so on becomes "pi=3.141593". I am aware of the following: ** gsubfn() in the 'gsubfn' package, e.g. > gsubfn( , , "pi = $pi, 2pi = `2*pi`") [1] "pi = 3.14159265358979,

Starting with the head of a 499 element matrix whose column names are now the labels trom a cut() operation, I needed to get to a vector of midpoints to serve as the basis for plotting a calibration curve ( exp(linear predictor) vs. : > dput(head(dimnames(mtcal)[2][[1]])) # was starting point testvec <- c("(-8.616,-3.084]", "(-3.084,-2.876]",

Hi, I don't know what I am doing wrong to the toupper does not seem working in sub + regex. The following returns 's' not the upper class 'S' as I expect: sub("q_([a-z])[a-zA-Z]*",toupper('\\1'),"q_sviRaw") Can someone tell me where I did wrong? Thanks, Richard [[alternative HTML version deleted]]

Hello, The code below works fine up until I try to use the "IN" statement in the last line. The proper SQL format is: SELECT * FROM this_table WHERE this_column IN (1,2,3,4,5) But, I think I may be getting something like: SELECT * FROM this_table WHERE this_column IN c(1,2,3,4,5) Which makes no sense in SQL. I think it may be just a matter of string massaging, but I'm not

Dear All, When one loads certain packages, some other dependent packages are loaded as well. Is there some way of detaching them automatically when one detaches the first package loaded? For instance, > library(sqldf) Loading required package: RSQLite Loading required package: DBI Loading required package: gsubfn Loading required package: proto but > detach(package:sqldf) > >

I have had some comments on sqldf regarding its dependence on tcltk such as the second last sentence on this blog post: http://translate.google.com/translate?hl=en&sl=zh-CN&u=http://www.wentrue.net/blog/%3Fp%3D453&prev=http://blogsearch.google.com/blogsearch%3Fhl%3Den%26ie%3DUTF-8%26q%3Dsqldf%26lr%3D%26sa%3DN%26start%3D10 sqldf does not directly use tcltk but it does use strapply in

Hi all, Does anyone have a version of strsplit that keeps the string that is split by. e.g. from x <- "A: 123 B: 456 C: 678" I'd like to get c("A:", "123 ", "B: ", "456 ", "C: ", 678) but strsplit(x, "[A-Z]+:") gives me c("", " 123 ", " 456 ", " 678") Any ideas? Thanks,

I have a text processing problem I'm hoping someone can help me solve. This issue it this. I have a character string in which I need to delete a variable number of characters from the string. The string itself contains the number of characters to be deleted. The number of characters to be deleted is proceeded by either a "+" or a "-". A toy example: Suppose I have

Hello, I have a dataframe (tab separated file) which looks like the example below - two values separated by a comma, and tab separation between each of these. [,1] [,2] [,3] [ ,4] [1,] 0,1 1,3 40,10 0,0 [2,] 20,5 4,2 10,40 10,0 [3,] 0,11 1,2 120,10 0,0 I would like to calculate the percentage of the smallest number separated by the comma by: 1) summing the values e.g. for

Hi again, how to elegantly split s <- "ABCDEFGT(P)HIJK" into "A" "B" "C" "D" "E" "F" "G" "T(P)" "H" "I" "J" "K" (independently of which letters 'T' or 'P' actually represent ...). Please jumstart my regexing, Joh

Dear Users, I am new to R, I have just downloaded it to play with. I am a Java & Matlab user, so I assume that it wouldn't be a hurdle. Where do I get to see the source codes for R sub-packages ? I looked at those sub-packages in folder 'R-ex' for the source codes and they are compressed files. Do I mean to de-compress these files where the source codes reside ? Any

Hi everybody, I am a new R user. Is there any package devoted to "text mining" analysis in R ? Thanks Gilles lepape.gilles at neuf.fr

Are there packages that allow improved String and URL processing? E.g. extract parts of a URLs such as sub-domains, top-level domain, protocols (e.g. https, http, ftp), file type based on endings, check if a URL is valid or not, etc... I am currently only using split and paste. Are there better and more efficient ways to handle strings e.g. finding sub-strings or to do pattern matching? What
