Hello List I'm trying to calculate the median period (in months) of a set of time intervals (between two interventions). I have been playing with the lubridate package to create the intervals but I can't think of the right approach to get the median timeperiod. Toy code: library(lubridate) test <- c('08-04-22', '08-07-28', '09-03-02', '09-03-03',

Agradezco la ayuda recibida me vino muy bien,,, el problema de instalar el paquete lubridate es que no está en los repositorios de Debian,,, al usar RStudio creo que se debe instalar en ~/R/x86_64-pc-linux-gnu-library previa compilación de fuente bajada de r-cran,,, cosa que será otro pedido de ayuda en el futuro si sale mal,,, Saludos Horacio El día 30 de diciembre de 2016, 7:05, Carlos Ortega

I have a mortality data over many years and I wish to plot the data and also add some smoother to clearly highlight the trend. How could I do that in R with base graphics or ggplot? I have the following sample data: require(lubridate) mdate<-seq(ymd('2000-01-01'),ymd('2010-12-31'), by = '1 day') death<- rnorm(4018, 80, 45) df<-cbind(mdate,death)

Version 2.2 of the lubridate package is now available. lubridate makes it easier to work with date-time data. For example, it provides: * simple functions to extract and modify components of a date-time, such as years, months, days, hours, minutes, and seconds: year(), month(), day(), ... * quick and easy functions to parse date-times: ymd(), dmy(), mdy(), ... * helper functions for handling

Please find below the package announcement for the R package lubridate available from cran. Thank you, Garrett Grolemund Rice University ##lubridate Date-time data can be frustrating to work with in R. R commands for date-times are generally unintuitive and change depending on the type of date-time object being used. Moreover, the methods we use with date-times must be robust to time zones,

I started to look at ways to improve times of certain very parallel tasks and thought that foreach should be a valid candidate to do the job. So, i opened foreach tutorial by Steve Weston and started timing examples from it. First example from tutorial is  >system.time(for(i in 1:100000) sqrt(i))    user  system elapsed     0.06    0.00    0.06  > system.time(foreach(i=1:100000) %do%

Buas y feliz año y decada nueva, compañeRos, Me estoy encontrando con un problema tonto que no consigo resolver. Explico, tengo un dato que necesito sacar en un documento con codigo on line y no me saca el resultado de consola. dato <- 2272.13 round(lubridate::seconds_to_period(seconds(dato))), 0) En consola me da: "37M 52S" Pero en el documento ```Rmarkdown + Duración total

Dear all, I wish to create a POSIXct variable from date and time variables using the ymd_hm function in package lubridate. In some cases data for time is missing, which causes a problem for ymd_hm. I wish to find a smooth way to handle this. # Some example data: x <- data.frame(date = c("2011-09-22", "2011-07-28"), time = c("15:00", NA)) x # paste date and

Hello, I have a list of dates in which I am going use for a time series analysis. I want to break these dates up into 2 week intervals and count the number of times a date appears in this interval. For example from Nov. 19, 2000 to Dec 2 ,2000 with the data listed below I want to return Start_date Count2000/11/19 4 Date: 2000/11/20 2000/11/21 2000/11/19 2000/11/29 My first approach was toa

Hola. Tengo una duda con esta sintaxis. Tengo una variable con formato Date que por algún motivo (el data.table viene de una consulta con PostgreSQL): datos <- prov[, pprid, pprfecbaja] str(datos) Cuando intento quitar las fechas de bajas inválidas (0001-01-01) y convertirlas a NA, la variable resultante "pierde" su condición de Date. Probé con distintas formas, siempre con el mismo

Hiya, maybe there is a native R function for this and if so please let me know! I have 2 data.frames with start and end dates, they read in as strings and I am converting to POSIXct. How can I check for overlap? The end result ideally will be a single data.frame containing all the columns of the other two with rows where there were date overlaps.

#lubridate lubridate makes it easier to work with dates and times by providing functions to identify and parse date-time data, extract and modify components of a date-time (years, months, days, hours, minutes, and seconds), perform accurate math on date-times, handle time zones and Daylight Savings Time. lubridate has a consistent, memorable syntax that makes working with dates less frustrating.

Greetings - I'm battling POSIXct, as per the code below. My input is actually an XL file, but the weird results below correctly model what I am seeing in my program. Before I punt and use lubridate or timeDate, could anyone please help me understand why POSIXct forces my variable back to GMT? I suspect that I'm not properly coding the tzone value, but it does not throw an

Hi, I wanted to learn how to solve a date and time manipulation where i can do the following two 1. difference of two dates eg (differnce between 5th jan 2013 and 1st jan 2013) 2.Suppose i have week number of the year, i want to know if i can find out the day it refers to eg( say week 2 of 2013 would be 6th jan 2013 and the day is sunday) i need my result to tell me that its
