In the text file pressione2008.csv I have the following "Data","MAX","MIN","Note" "07-01-2008 08:00:00", 135, 90, "Eccessi feste, inizio dieta" "07-01-2008 18:00:00", 135, 85, "" "08-01-2008 08:00:00", 125, 75, "" which is a collection of blood pressure data at different time of the day. I would like to build an its with MIN & MAX blood pressure but being a real newbye with zoo I o...

ng, I have a matrix (x) with binary content. Each row of the matrix holds exactly one 1, and the rest of the row is zeros. The thing is that I need to 'collapse' the matrix to one column where each row holds the original column index of the 1's (y). Sometimes, the matrix is quite large, so I have a perfomance problem. x <- matrix(c(1,0,0, 0,0,1, 0,1,0, 0,0,1, 0,1,0,

hi, I have some session data in a dataframe, where each session is recorded with a start and a stop date. Like this: session_start session_stop =================== 2009-01-03 2009-01-04 2009-01-01 2009-01-05 2009-01-02 2009-01-09 A session is at least one day long. Now I want a dataframe with 'active sessions' per date. Like this: date active_sessions ============= 2009-01-01 1

I'm trying to create a new column in my data.frame where subjects are categorized depending on values on four other columns. In any other case I would just nest a few ifelse statements, however, in this case i have 4*6*2*3=144 combinations and i get weird 'context overflow' errors. So I wonder if there is a more efficient way of doing this. For illustrational purposes, let's say

Hi, A small (but annoying) problem with RMySQL library. When a connection is closed, it echoes 'TRUE' to the console. Like this: R> mysqlCloseConnection(con) [1] TRUE The real problem comes when I use RMySQL with Sweave, since the TRUE echo gets into my final Sweave document. Even when I explicitly state <<include=FALSE, echo=FALSE>>= in the header of the R code chunk.

Hi everyone, I'm new in this list and I hope I'll write my problem in a right way. So, this is my problem: Every an undefined time (It could be 5 min or 20 min) my pc restarts the samba service and It writes this line on the screen: "Reloading /etc/samba/smb.conf smdb only" I have Ubuntu Server 9.10 x32. I am looking for fix this problem for a long time but I don't know

Hi, I've set up a very simple R repository. Just a single source library. Everything works fine. I can install the package on my client using: install.packages(repos='http://www.myServer.se/myRepo/', pkgs='myLib', dep=TRUE) However, I want to protect the repo, so I use a .htaccess, placed directly under 'myRepo' on the server. I use 'Authentication Basic' and

I'm trying to dynamically build variable names to use on a list. Let's say I have a list like this one: l <- list(V1_1=c(1,2,3), V1_2=c('One','Two','Three')) And I succesfully build my variable name like this: paste('l$', 'V1_1', sep='') Why can't I just run a mean call with the pasted variable name? mean(paste('l$',

Hi, I'm trying to create a distance matrix. And it works out somewhat ok. However, I suspect that there are some efficiency issues with my efforts. Plz have a look at this: donor <- matrix(c(3,1,2,3,3,1,4,3,5,1,3,2), ncol=4) receiver <- matrix(c(1,4,3,2,4,3,1,5,1,3,2,1,4,5,3,5,1,3,2,4,5,1,2,3,1,4,5,5,1,2,1,3,4,3,2,5,5,1,4,2,5,4,3,2), ncol=4) The above creates my two matrices. I have

I'm trying to typeset at simple crosstable with the Hmisc latex function. And I have two problems. 1. How do I make all columns the same width? The Latex function seems very unwilling to break the 'cgroup' labels and the factor level labels. Please have look at this screenshot that shows my problem: >> http://hem.passagen.se/stpe9096/table.png So, how can I make sure that the

I have an MS Access database with one table and one column holding rep(1:10) I use: library(RODBC) channel <- odbcConnect("test") sqlQuery(channel, paste("SELECT col FROM tblTest"), believeNRows=FALSE) and get: 49 50 51 52 53 54 55 56 57 12337 What? The above should, of course, read: 1 2 3 4 5 6 7 8 9 10 I tried the 'odbcQuery' /

Hi, Sorry for my ignorance, but how can I see if a function is 'compiled code' or plain R? E.g. the daisy function from the cluster package.

Hi, I have two groups, and I want to find the dissimiarity between the members of the two groups. Since I have mixed level variables on the members, I opt for the daisy function in the cluster package. Let's pretend that the following represent my groups: x <- data.frame(sex=factor(c(1,0,0,1,0,1), levels=0:1, labels=c('Male','Female'), ordered=FALSE),

I often read SPSS system files (*.sav) into R using the 'read.spss' function from the 'foreign' library. To retain all the meta data, i.e. 'variable labels', I call the function like this: test.sav <- read.spss('http://www.cdc.gov/healthyYouth/shpps/2006/spss/envs2006.sav', to.data.frame=FALSE, use.value.labels=TRUE ) This returns a list, which is fine.

Hi, I'm trying to build a vector of latex commands. However, I need the command strings to begin with a backslash "\". I have: test <- c('foo','bar') and I need to rebuild the array, encapsulating the text items with latex stuff, like this: paste("\parbox[b]{3cm}{", test, "}", fill=TRUE) Actually, cat() prints the string fine if one uses

First, I don't have the correct lingo for this topic, so I can't really find a solution for my problem. And maybe I formulate it incorrectly, so bear with me. How would I calculate a 'constant transition matrix' if I know a given value at a given time? Let's say I know that my value is 54,0 at t=12. How do I get the initial chain value? t markov.growth 00 00.0 01 06.3
