converting datetime string to POSIXct date/time format in R

datetime, posixct, r, string

Solution

You need to specify a format for your conversion. Take a read of `?strptime` to see all of the options for date formats.

#YYYY-MM-DDT00:00:00.000-08:00
test <- "2013-12-25T04:32:16.500-08:00"
z <- as.POSIXct(test,format="%Y-%m-%dT%H:%M:%OS")
op <- options(digits.secs = 3)
z
#[1] "2013-12-25 04:32:16.5 EST"

Problem

Consider a string in the format ``` test <- "YYYY-MM-DDT00:00:00.000-08:00" ``` My goal is to convert those strings to `POSIXct` format so that I can plot the data. my initial thought was to use ``` as.POSIXct(test) ``` ...but that seems to truncate the datetime to just date. Any thoughts? The help info for `as.POSIXct` seems to imply that the input should be date and time separated by a space, not by a "T". Is this my issue?
