I have a problem ordering by descending magnitude a POSIXt object. Can someone help please and let me know how to work around this. My goal is to be able to order my data by DATE and then by descending TIME. I have tried to include as much info as possible below. The problem stems from trying to read in times from a CSV file. I have converted the character time values to a POSIXt object using the

...h it is applied. quick reason: tapply strips class when simplify is set to TRUE (the default) due to the class stripping behaviour of unlist. quick answer: This can be fixed by invoking tapply with simplify=FALSE, or changing tapply to use do.call(c instead of unlist executable example: mytimes=data.frame(date = 1:3 + Sys.time(), set = c(1,1,2)) by(mytimes$date, mytimes$set, function(x)x) INDICES: 1 [1] "2008-04-15 11:41:38 BST" "2008-04-15 11:41:39 BST" ---------------------------------------------------------------------------------------- INDICES: 2 [1] "2008...

Dear List, I have a data frame of data taken every few seconds. I would like to subset the data to retain only the data taken on the quarter hour, and as close to the quarter hour as possible. So far I have figured out how to subset the data to the quarter hour, but not how to keep only the minimum time for each quarter hour. For example:

Dear R users, How to change lattice panel label/text from the automatically generated label (based on the conditioning) to our own set of label? for example: someStuff <- data.frame(area = rep(c("SOUTH", "NORTH", "EAST", "WEST"), each = 25), group = rep(c("A","B","C","D"), each = 5),

Hi, I have problem with upssched on windows. Upssched is not executed. I have 2 scripts, 1 for notification in upsmon and second for scheduling in upssched. Monitoring is working fine, script write to log. I'm using binary windows installer 2.6.5-6 from NUT. Here are my configs: --- nut.conf MODE=netclient --- upsmon.conf MONITOR ups_1000 at 192.168.3.95 1 <user> <password> slave

Dear all, I am trying to fit a non linear regression model to time series data. If I do this: reg.logis = nls(myVar~SSlogis(myTime,Asym,xmid,scal)) I get this error message (translated to English from French): Erreur in nls(y ~ 1/(1 + exp((xmid - x)/scal)), data = xy, start = list(xmid = aux[1], : le pas 0.000488281 became inferior to 'minFactor' of 0.000976562 I then tried to set

I have defined a daily timeseries for the 365 days of 2003 issuing: myts = ts(dati[,2:10],frequency=365,) > myts Time Series: Start = c(1, 1) End = c(1, 365) Frequency = 365 and mytime = as.POSIXct(strptime(as.character(dati[,1]),format="%Y-%m-%d")) contains the dates from "2003-01-01" to "2003-12-31" How can I combine mytime and myts in order to list

Hello all, I don' like to have ( ) around my datetime, when send the csv file to somebody. How to remove it? >library(chron) >mydate <- c("2009-05-03","2009-06-07") >mytime <- c("10:30:00","10:20:00") >mydatetime <- chron(dates=mydate,times=mytime,format=c("y-m-d","h:m:s")) >write.csv(mydatetime)  

Hello everyone, I have a character vector of 24 hour time values in the format hm without the delimiting ":". How can I insert the ":" immediately to the left of the second digit from the right? mytimes<-scan(what="") 1457 1457 1310 1158 137 1855 Thanks! Dan

Due to the following lines in parse.format: else if (nf == 3) { sep <- "" fmt <- substring(format, first = 1:3, last = 1:3) } If a format code has 3 characters, it will not use a separator: > library(chron) > mytime = times('7:15:00') > format(mytime,'h:m') [1] "0715" - Phil Spector

I''ve got a problem with timing out a C RFC call. Essentially, I''ve got code that initializes and executes an RFC to a remote server that, depending on the server, could take a significant amount of time to return a response. To minimize end-user impact, I wrapped the call with a timeout of 20 seconds. When I executed a test, it didn''t appear to do anything as the

Hi,all I only got the time data such as: tms<-c("19:30:23","18:39:10".....) I want to manipulate this time series data. For example, plus one second(or minute) or minus one second This data only has the time(h:m:s), without the date. I know that there are chron package, ISOPix class and the timeDate class, but all these class need the input of date. How can we

Hello, I have two gamm question (I am using gamm in mgcv). 1. In have, say 5 time series. Monthly data, 20 year. The 5 time series are from 5 stations. The data are in vectors, so I have fitted something along the lines of: tmp<-gamm(Y ~ s(Year,by=station1)+s(Year,by=station2)+ s(Year,by=station3)+s(Year,by=station4)+

...uot;%m/%d/%Y %H:%M")) And create a plot as such: plot(MyTime,MyData) ---------------------------------------------------------- And here is a specific question: How do I calculate the number of months than are spanned between two POSIXct values? (i.e. NumOfMonths <- MonthFunction(range(MyTimeStampData)) Thanks-in-advance, - rich

Hi, I'm interested in building a Cox PH model for survival modeling, using 2 covariates (x1 and x2). x1 represents a 'baseline' covariate, whereas x2 represents a 'new' covariate, and my goal is to figure out where x2 adds significant predictive information over x1. Ideally, I could get a p-value for doing this. Originally, I thought of doing some kind of likelihood ratio
