tidy.sts: Convert an "sts" Object to a Data Frame in Long (Tidy) Format
Description
The resulting data frame will have a row for each time point and
observational unit, and columns corresponding to the slots of the
"sts" object (except for populationFrac,
which is named population).
Some time variables are added for convenience:
year, epochInYear, epochInPeriod, date
(the latter gives NA dates if epoch(x, as.Date=TRUE)
fails, i.e., for non-standard frequency(x) if x@epochAsDate is false).
data("momo")
momodat <- tidy.sts(momo)
head(momodat)
## tidy.sts(stsObj) is the same as as.data.frame(stsObj, tidy = TRUE)stopifnot(identical(as.data.frame(momo, tidy = TRUE), momodat))
