There are many R packages for working with Time Series data. Here’s
timetk compares to the “tidy” time series R packages for data
visualization, wrangling, and feature engineeering (those that leverage
data frames or tibbles).

Timetk is an amazing package that is part of the
for time series analysis and forecasting. The forecasting system is
extensive, and it can take a long time to learn:
- Many algorithms
- Ensembling and Resampling
- Machine Learning
- Deep Learning
- Scalable Modeling: 10,000+ time series
Your probably thinking how am I ever going to learn time series forecasting. Here’s the solution that will save you years of struggling.

Time Series is Changing
Time series is changing. Businesses now need 10,000+ time series forecasts every day. This is what I call a High-Performance Time Series Forecasting System (HPTSF) - Accurate, Robust, and Scalable Forecasting.
High-Performance Forecasting Systems will save companies by improving accuracy and scalability. Imagine what will happen to your career if you can provide your organization a “High-Performance Time Series Forecasting System” (HPTSF System).
How to Learn High-Performance Time Series Forecasting
I teach how to build a HPTFS System in my High-Performance Time Series Forecasting Course. You will learn:
- Time Series Machine Learning (cutting-edge) with
Modeltime- 30+ Models (Prophet, ARIMA, XGBoost, Random Forest, & many more)
- Deep Learning with
- Time Series Preprocessing, Noise Reduction, & Anomaly Detection
- Feature engineering using lagged variables & external regressors
- Hyperparameter Tuning
- Time series cross-validation
- Ensembling Multiple Machine Learning & Univariate Modeling Techniques (Competition Winner)
- Scalable Forecasting - Forecast 1000+ time series in parallel
- and more.

timetk package wouldn’t be possible without other amazing time
- stats - Basically every
timetkfunction that uses a period (frequency) argument owes it to
timetkmakes heavy use of
duration()for “time-based phrases”.
- Add and Subtract Time (
"2012-01-01" %+time% "1 month 4 days"uses
lubridateto intelligently offset the day
- Add and Subtract Time (
- xts: Used to calculate periodicity and fast lag automation.
- forecast (retired): Possibly
my favorite R package of all time. It’s based on
ts, and it’s predecessor is the
ts_impute_vec()function for low-level vectorized imputation using STL + Linear Interpolation uses
na.interp()under the hood.
ts_clean_vec()function for low-level vectorized imputation using STL + Linear Interpolation uses
tsclean()under the hood.
- Box Cox transformation
timetkdoes not import
tibbletime, it uses much of the innovative functionality to interpret time-based phrases:
seq.POSIXt()using a simple phase like “2012-02” to populate the entire time series from start to finish in February 2012.
between_time()- Uses innovative endpoint detection from phrases like “2012”
- slider: A powerful R package that
purrr-syntax for complex rolling (sliding) calculations.
slider::pslideunder the hood.
slider::slide_vec()for simple vectorized rolls (slides).
- padr: Used for padding time series
from low frequency to high frequency and filling in gaps.
pad_by_time()function is a wrapper for
- See the
step_ts_pad()to apply padding as a preprocessing recipe!
- TSstudio: This is the best
interactive time series visualization tool out there. It leverages the
tssystem, which is the same system the
forecastR package uses. A ton of inspiration for visuals came from using
