Dear R forum I have a data.frame as cashflow_df = data.frame(instrument = c("ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC", "ABC", "PQR", "PQR",

Hi, I want to construct a data.frame 'y' by using x$x and x$y. I think that there might be better ways to do it (because, for example, we can use a_matrix[3:5,] to extract certain rows, where 'a_matrix' is a matrix). Can somebody let know what the best way is? > a=data.frame(x=1:10,y=rep("abc",10),z=rep("xyz",10)) > a x y z 1 1 abc xyz 2 2

Hi I rsync from 4 machines to a single destination one, and I am certain the filenames they sync do not overlap. But from time to time rsync from a source machine gets stuck (not always the same source machine). I followed https://rsync.samba.org/issues.html and I gathered strace, lsof and netstat when the freeze occurred. I'd like to ask for any further debug info or ideas! General info

With 0.64.1 on Intel RH5.2, abc <- list() abc$abc$abc <- matrix(1:20) mt <- terms(~(abc$abc$abc[,1]==64)|(abc$abc$abc[,1]==65)|(abc$abc$abc[,1]==75) |(abc$abc$abc[,1]==84)|(abc$abc$abc[,1]==85)) model.matrix(mt,model.frame(mt)) crashes. With ab$ab$ab, it does not. Apparently, the bug I reported for 0.64.0 has just been pushed back one step. Jim

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",

Hello, I have a basic e-mail server with Postfix 3.1 and Dovecot 2.2.22. I am using a passwd-file for both userdb and passdb: /etc/dovecot/dovecot.conf userdb { driver = passwd-file args = /etc/dovecot/passwd } passdb { driver = passwd-file args = /etc/dovecot/passwd } } In the passwd file, I want to have

Hi, I was playing around with inotifywait (great tool!) to see the new staged installation of source packages in action. In one terminal I'm monitoring the create/delete/move events of the installation library with: ? inotifywait -m --timefmt '%F %T' --format '%T -- %w %e %f' -e create -e delete -e move path/to/R/library/ While in another terminal I install CRAN package

Here is a possible BUG with as.data.frame() and/or [.data.frame which broke Michael Lapsleys RODBC-Code. Can anyone confirm it is a bug or a 'feature' of the prototype? tablename <- "abc" a <- as.data.frame(cbind("abc", 1:3)) b <- as.data.frame(cbind(tablename, 1:3)) # ok > a V1 V2 1 abc 1 2 abc 2 3 abc 3 # missing column name > b tablename 1

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

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

Naming difference in cbind between S-Plus and R. I think R is wrong. abc <- data.frame(y=1:4, x=rnorm(4)) abc.lm <- lm(y ~ x, data=abc) predict.lm(abc.lm, type="terms") ## this is where R got the name "x" abc <- cbind(abc, d=abc$y - predict.lm(abc.lm, type="terms")) abc R gives > abc y x x 1 1 -1.33925477 1.163001 2 2 1.52764505

Hi, I have a setup problem with Shorewall 4.0.6, which I can''t figure out why it is not working: I want to install a fireall with 2 extra interfaces : - My serv ("dmz") zone is a /28 subnet behind eth1, with a small number of SUN servers (IPs between ABC.DEF.75.1 and .13), one of which is a DHCP server for the 75 subnet. - The loc zone are PCs in the 75 subnet behind eth2

temp.ttt <- "ttt <- 1\nttt" conn.ttt <- textConnection(temp.ttt) source(conn.ttt, echo=TRUE) ## name of variable is echoed close(conn.ttt) cat(file="c:/temp/temp.R", temp.ttt) ## name of variable not echoed source("c:/temp/temp.R", echo=TRUE) temp.abc <- "abc <- 1\nabc" conn.abc <- textConnection(temp.abc) source(conn.abc, echo=TRUE)

Dear R users, Suppose I have a vector that consists of characters like ABC, A02, RCA, etc., and there are about 700 of possible characters. For example, x <- c("ABC", "ABC", "ABC", "A02", "ABC", "RCA", "ABC", "ABC") I'd like to get a frequency matrix that looks something like this: ABC 6 A02 1 RCA 1 I

How do I remove a "$" character from a string sub() and gsub() with "$" or "\$" as pattern do not work. > sub("$","","ABC$DEF") [1] "ABC$DEF" > sub("\$","","ABC$DEF") Error: '\$' is an unrecognized escape in character string starting "\$" >

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"

Hi, I've tried various combinations of --exclude and --include, but I can't quite get it. What I'd like to do is only mirror certain directories in a tree. For example, say a directory tree starting at /x contained under it several directories named "abc". I want to mirror only the "abc" directories and what's under them and nothing else. /x/abcdef/456
