To better visualize time-series dataset, 'TSplotly' package provides an effective mechanism to utilize the powerful 'plotly' package for graphing time series data. It contains 5 core functions: TSplot(): create interactive plot on time series data or fitted ARIMA(X) models. ADDline(): add lines on existing 'TSplot()' objects, as needed. GGtoPY(): create a convenient way to transform (reformat) 'ggplot2' datasets into a format that can work on 'plot_ly()'. GTSplot(): create multiple 'plot_ly()' lines (time-series) based on data frames containing multiple time-series data. TSplot_gen(): a more general version of function 'TSplot()' that can work on any time format.
