similar to: data.frame into list by columns; merge and row.names

Hi I want to extract a row from a data.frame but I want that object to be a vector . After trying some different ways I end up always with a data.frame or with the wrong vector. Any pointers? x <- data.frame(a = factor(c('a',2,'b')), b = c(4,5,6)) I want to get "a" "4" I tried: as.vector(x[1,]) a b 1 a 4 (resulting in a data.frame even after in my

Hi I want to extract all the rows in a data frame that have duplicates for a given column. I would expect this question to come up pretty often but I have researched the archives and surprisingly couldn't find anything. The best I can come up with is: x <- data.frame(a=c(1,2,2,3,3,3), b=10) xdup1 <- duplicated(x[,1]) xdup2 <- duplicated(x[,1][nrow(x):1])[nrow(x):1] xAllDups <-

Dear R-listers: I want to import a reasonably big file into a table. (15797 x 257 columns). The file is tab delimited with NA in every empty space. I have reproduced what I have used as my read.table instruction. I have read the R-dataImportExport FAQ and still couldn't solve my problem. (I might have missed it, of course). I'm using R.2.01 in a Mac G4, 10.3.7. I can import the

Hi I have two basic questions, and here they go, but I was wondering as well where can I ask these basic questions without bothering you people I've used Splus and now I'm using R and there's some functions that I can't simply find one: sort.col that allows data.frames to be sort by a given col (I saw the funtion sort but that's for vectors. and I can't believe I

Hi to you all My question is: there is a package written in UNIX for which there is no Mac version. I would like to know if it's possible to install the R UNIX version on the MacOSX and run that UNIX package on my Mac (through this UNIX R Vresion on a Mac) I have seen a porfile for r version 1.8.1 on darwin: http://r.darwinports.com/ is that it? aother question related to that if it's

Dear All, Suppose I have a program as below: Outside is a loop for simulation (with random generated data), inside there are several sapply()'s (10~100) over the data and something else, but these sapply's have to be sequential. And each sapply do not involve very intensive calculation (a few seconds only). So the outside loop takes minutes to finish one iteration. I guess the better way

I would like to assign an value to an element of a list contained in an environment. The list will contain vectors and matrices. Here's a simple example: # create toy environment testEnv = new.env(parent = emptyenv()) # create list that will be in the environment, then assign() it x = list(a=1,b=2) assign("xList",x,testEnv) # create new element, to be inserted into xList c = 5:7

Hi All, I'm trying to configure Dovecot 2.0.9 to support Outlook 2013. As I understand it, I need to configure XLIST. I have added imap_capability = +XLIST to 20-imap.conf When I try to query the IMAP folders I get an error "An IMAP command Failed". Looking at the logs I get XLIST Command not found. I can only assume that I'm missing something in the

Hello list, my question is related to svd of a matrix: b=matrix(rnorm(50),10,5) mysvd=svd(b) I would like to compute each xi where xi = di* ui %*% t(vi). I do it by : xlist=sapply(1:ncol(b), function(x1,y) y$d[x1]*y$u[,x1]%*%t(y$v[,x1]),y=mysvd,simplify=F) # result is a list xarray=array(sapply(1:ncol(b), function(x1,y) y$d[x1]*y$u[,x1]%*%t(y$v[,x1]),y=mysvd),c(nrow(b),ncol(b),ncol(b))) #

Hi I have a data.frame with 2 columns. The first column is an ID column. The other columns are description of the ids. There is more than one description for each Id. Want I want to get as a value is a data.frame where each row corresponds to one ID and has as many columns as different descriptions. I have used a very convoluted step, but I'm very convinced there is an easier way to do

Hello, i use dovecot 2.1.7 and exported all my XLIST FolderSettings to userdb Whole Story is here: http://dovecot.org/list/dovecot/2013-March/089209.html This is all successful, but there is one problem left. I use lines like this to realize individual XLIST Foldernames in usedb: namespace/inbox/mailbox=Sent namespace/inbox/mailbox/Sent/name=Sent namespace/inbox/mailbox/Sent/auto=subscribe

Very interesting topic. "What I want to know is *WHY* people are doing this?" Here goes my view - I've used many for loops, and each time I realize how stupid that is... AFTER I learned how to avoid it. But it's difficult to avoid them without knowing how to do it. (Monsieur de LaPalice wouldn't have puted it better...) For loops are conceptually very easy to understand.

Hello, I'm hosting a few customers on a dovecot Server. Most users speak german and have german as their main language. I configured the IMAP Foldernames in a Dovecot configuration file like this: ##### root at srv04:~# cat /etc/dovecot/conf.d/105-mailboxes.conf imap_capability = +XLIST namespace inbox { inbox = yes location = separator = / mailbox "Entw?rfe" { auto

I am trying to make a graph with 4 scatter matrixes plots and couldn't do it. While trying to find a solution for this I also came across the idea of giving different values to the same argument for each of the lower and upper function but couldn't do it. (Examplified below with the col argument). The first problem of plotting 4 scatter matrixes in a graph is a problem of real

I know that is is not really a Dovecot problem; however, I was wondering where I could get a complete list of the terms used in the 'capability' line. I have not had any success in finding out what things like "XLIST" refer to. I don't believe that is one that Dovecot uses; however, I have seen it with other IMAP servers, plus lots of other flags that I do not understand. I

Someone should at least mention that they should support the real SPECIAL-USE instead of just Gmail-specific XLIST..

Hello all, I want to extend a draggable object so it has one more attribute (type attribute, so I can distinguish different draggable types). Can anyone tell me how to do it?
