Dear All, I'd like to know if it is possible to create animations with R. To be specific, I attach a code I am using for my research to plot some analytical results in 3D using the lattice package. It is not necessary to go through the code. Simply, it plots some 3D density profiles at two different times selected by the user. I wonder if it is possible to use the data generated for different

Dear All, I am trying to use the do.call command to avoid tedious loops in R when I need to call repetitively a function. I am experiencing a problem when the arguments of a function are given with a vector (I need to express then this way to be able later on to integrate them numerically with the adapt package). Consider the small script: remove(list=ls()) #library(adapt) # first a list of the

Dear R Community, I am new to R, and have a question that I suspect may be quite simple but is proving a formidable roadblock for me. I have a large data set that includes water-quality measurements collected over many 24-hour periods. The date and time of sample collection are in a combined Date/Time field in the format yyyy-mm-dd hh:mm:ss. I need to be able to subset the data for analysis of

Dear list, When I read some source code, I find lot of place used symbol <<- , e.g. lastTime <<- newTime; What is the meaning here? Also, I find some method with the name start with dot, e.g. .RowStandardizeCentered = function(x) { div = sqrt( rowSums(x^2) ); div[ div == 0 ] = 1; return( x/div ); } What is the special meaning for the method name start with a dot? Thank you

OK, I need help!! I've been searching, but I don't understand the logic of some this dataframe addressing syntax. What is this type of code called? test [["v3"]] [is.na(test[["v2"]])] <-10 #choose column v3 where column v2 is == 4 and replace with 10 and where is it documented? The code below works for what I want to do (find the non-missing value in a row),

Description of Problem We are rapidly approaching the time of year when some will transition from standard time (ST) to daylight savings time (DST) and others will make the opposite transition. These vernal and autumnal transitions have important implications for those with Microsoft systems and use utilities that compare file timestamps on different filesystem types or with filesystems on other

Hi, If I have the following data.frame >y time val 1 08:00:05.834 1 2 08:03:13.345 2 3 08:10:12.443 3 > and the following function which converts the time string to the number of milliseconds since midnight > str_to_millis function( s ) { a <- as.numeric( unlist( strsplit(s,":",fixed="TRUE") ) ) m <- a[1]*3600000 + a[2]*60000 + a[3]*1000 }

One variable contains values (1.30 - one hour and thirty minutes, 1.2 (which is supposed to be 1.20 - one hour and twenty minutes)). I would like to convert to a minute variable so 1.2 is converted to 80 minutes. How?

Dear List, Does anybody no how to compare mean survival times for two (more) groups in R? What test statistics should I use? Thank you very much! Joe [[alternative HTML version deleted]]

Hello all, I'm having a problem with data handling. My input data is (dput in the after the signature): Date Time Fraction 06/19/13 22:15:39 0.3205 06/19/13 22:15:44 0.3205 06/19/13 22:15:49 0.3205 06/19/13 22:15:54 0.3205 06/19/13 22:15:59 0.3205 06/19/13 22:16:09 0.3205 Date in format month/day/year, Time in HH:MM:SS and fraction represents the fractions of

Recently various needs for multiple version handling were discussed and I put forward a plan of mine. Subsequently the proposal for a --compare-file=<FILE> switch had support, so I have implemented this. I have also implemented an experimental --compare-auto which decides which file to match against using a rule. Instructions for patch: 1. Install rsync-2.5.6 source 2. "patch -p1

Hello, I have some question on chron I currently doing this t1 <- chron(,"11:30:00") t2 <- chron(,"11:45:00") tt <- seq(t1,t2,by=times("00:00:01")) tt has 901 values (15 minutes * 60 secs) and then x1 <- rnorm(1:901) x2 <- rnorm(1:901) x3 <- rnorm(1:901) df <- data.frame(tt, x1, x2, x3) I would like to write a function such that I can

Hi everyone, My question will probably seem simple to most of you, but I have spent many hours trying to solve it. I need to perform a series of sequential calculations on my dataframe that move across rows and down columns, and then repeat themselves at each unique 'MM' by 'DD' grouping. Specifically, I want to add 'DEPART' time (24 hr time) to 'TRAVEL'(minutes)

As suggested, I checked that I was getting wine of the right vintage, and as you see below, I indeed seem to have the version designated by the codeweavers rpm name I downloaded (codeweavers-wine-20011108-5.i386.rpm): [cafl@emma cafl]$ which wine /usr/bin/wine [cafl@emma cafl]$ /usr/bin/wine --version Wine release 20011108 Wine exited with a successful status [cafl@emma
