tidytime

Functions for tidying time series objects. tidytime can tidy ts, xts and zoo objects. The zoo tidier is identical to that available in the broom package, except that it returns a dplyr::tbl_df.

All tidied time series have the following columns:

• index: time value from the messy data. Can be dbl, date or time.
• series: column with a descriptor for the type of messy data.
• value: values from the original time series.

library(xts)
data(sample_matrix)
sample.xts <- as.xts(sample_matrix, descr='my new xts object')

tidytime(sample.xts)

zoo objects

library(zoo)
