Loading a TCPD dataset into R

The file load_dataset.R contains the function load.dataset that reads the JSON file into an R dataframe. The RJSONIO package is required:

> install.packages('RJSONIO')

Simply run:

> source('./load_dataset.R')
> df <- load.dataset('../../datasets/ozone/ozone.json')
> df
    t Total Emissions
1   0          380000
2   1          400000
3   2          440000
4   3          480000
5   4          510000
6   5          540000
7   6          580000
8   7          630000

Notice that the time axis in TCPD is always 0-based. This needs to be taken into account when comparing detection results to the human annotations. (This is an unfortunate consequence of the differences between indexing in R and Python.)

Missing observations in time series are represented with a NA value.
