Pass an Earth Engine date object to R
eedate_to_rdate(ee_date, timestamp = FALSE)ee$date object (ee$Date)
Logical. If TRUE, return the date in milliseconds from the Unix Epoch (1970-01-01 00:00:00 UTC). Otherwise, return the date as a POSIXct object. By default FALSE.
eedate_to_rdate will return either a numeric timestamp or
a POSIXct object depending on the timestamp argument.
eedate_to_rdate is essential to avoid potential errors that
might appear when users need to retrieve dates. Currently,
R integer only supports 32 bit signed (such integers can only
count up to about 2 billion). This range is notably insufficient for dealing
with GEE date objects represented by timestamps in milliseconds since the
UNIX epoch. eedate_to_rdate uses Python in the backend to obtain the
date and convert it in float before exporting to R.
Other date functions:
ee_get_date_ic(),
ee_get_date_img(),
rdate_to_eedate()
if (FALSE) {
library(rgee)
ee_Initialize()
eeDate <- ee$Date$fromYMD(2010,1,1)
eedate_to_rdate(eeDate,timestamp = TRUE) # good
eeDate$getInfo()$value # bad
}
