median time period
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',

lubridate v2.2 available on cran
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

Plot mortality data and show trend
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)

New package: lubridate 0.1
Please find below the package announcement for the R package lubridate

##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,

foreach takes foreever?
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%

lubridate:ymd_hm and coercion of class POSIXct. Smooth way to restore the date format.
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))

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.

Ayuda con Date
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

lubridate and intervals
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 1.1.0
#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.

DateTime Math in R - POSIXct
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

tidy.source() gets confused when # is not a comment but a part of a literal string?
I needed to clean someone else code and run it through tidy.source. It encountered a number of hangups which after some experimentation lead me to suspect that the culprit is # symbol when it is a part of literal string. For example if i copy the following to the clipboard
confuse.tidy <-
function()
{
txt <- 'abra # cadabra'
}
and run with default arguments
>tidy.source()
