Beyond the imputation algorithms the package also provides plotting and printing functions of time series missing data statistics. Additionally three time series datasets for imputation experiments are included.\n\n## Installation\n\nThe imputeTS package can be found on [CRAN]. For installation execute in R:\n\n```\n install.packages(\"imputeTS\")\n```\n\nIf you want to install the latest version from GitHub (can be unstable) run:\n\n```\nlibrary(devtools)\ninstall_github(\"SteffenMoritz/imputeTS\")\n```\n\n## Usage\n* #### Imputation\n\n  To impute (fill all missing values) in a time series ***x***, run the following\n  command:\n  ```\n   na_interpolation(x)\n  ```\n  Output is the time series ***x*** with all NA's replaced by reasonable values.\n\n  \u003e This is just one example for an imputation algorithm. \n  \u003e In this case interpolation was the algorithm of choice for \n  \u003e calculating the NA replacements. There are several other \n  \u003e algorithms (see also under caption \"Imputation Algorithms\"). All \n  \u003e imputation functions   are named alike starting with\n  \u003e na_ followed by a algorithm label  e.g. na_mean, na_kalman, ...\n\n\n* #### Plotting\n\n  To plot missing data statistics for a time series ***x***, run the following\n  command:\n  \n  ```\n   ggplot_na_distribution(x)\n  ```\n  \n  \u0026nbsp;\n\n  \u003cp align=\"center\"\u003e\n  \u003cimg src=\"man/figures/ggplot_na_distribution.png\" width=\"600\" height=\"350\" alt=\"Example ggplot_na_distribution plot\" /\u003e\n \u003c/p\u003e\n  \n  \n  \u003e This is also just one example for a plot. Overall there are four different types \n  \u003e of missing data plots. (see also under caption \"Missing Data Plots\"). \n\n* #### Printing\n\n  To print statistics about the missing data in a time series ***x***, run the\n  following command:\n  ```\n   statsNA(x)\n  ```\n  \n* ### Datasets\n\n  To load the *'heating'* time series (with missing values)  into  a variable ***y*** and the *'heating'* time series (without missing values) into a variable ***z***, run: \n  \n  ```\n   y \u003c- tsHeating\n   z \u003c- tsHeatingComplete\n  ```\n  \n  \u003e There are three datasets provided with the package, the *'tsHeating'*, the \n  \u003e *'tsAirgap'* and the *'tsNH4'* time series. (see also under caption \"Datasets\"). \n\n\n## Imputation Algorithms\n\nHere is a table with available algorithms to choose from:\n\n|      Function        |           Description                                      | \n| :--------------------|:-----------------------------------------------------------|\n| na_interpolation     |Missing Value Imputation by Interpolation                   |\n| na_kalman            |Missing Value Imputation by Kalman Smoothing                |\n| na_locf              |Missing Value Imputation by Last Observation Carried Forward|\n| na_ma                |Missing Value Imputation by Weighted Moving Average         |\n| na_mean              |Missing Value Imputation by Mean Value                      | \n| na_random            |Missing Value Imputation by Random Sample                   | \n| na_remove            |Remove Missing Values                                       | \n| na_replace           |Replace Missing Values by a Defined Value                   | \n| na_seadec            |Seasonally Decomposed Missing Value Imputation              | \n| na_seasplit          |Seasonally Splitted Missing Value Imputation                | \n\n  \u003e This is a rather broad overview. The functions itself mostly offer more\n  \u003e than just one algorithm. For example na_interpolation can be set to linear\n  \u003e or spline interpolation.\n\nMore detailed information about the algorithms and their options can be found in the [imputeTS reference manual].\n\n## Missing Data Plots\n\nHere is a table with available plots to choose from:\n\n|      Function           |           Description                                        | \n| :-----------------------|:-------------------------------------------------------------|\n| ggplot_na_distribution  |Visualize Distribution of Missing Values                      |\n| ggplot_na_distribution2     |Missing Values Summarized in Intervals                        |\n| ggplot_na_gapsize       |Visualize Distribution of NA Gapsizes                         |\n| ggplot_na_imputations   |Visualize Imputed Values                                      | \n\nMore detailed information about the plots can be found in the [imputeTS reference manual].\n\n\n### Datasets\n\nThere are three datasets (each in two versions) available:\n\n|      Dataset     |             Description                                          | \n| :----------------|:-----------------------------------------------------------------|\n| tsAirgap         |Time series of monthly airline passengers (with NAs)              |\n| tsAirgapComplete |Time series of monthly airline passengers (complete)   |\n| tsHeating        |Time series of a heating systems supply temperature (with NAs)    |\n| tsHeatingComplete|Time series of a heating systems supply temperature (complete)    |\n| tsNH4            |Time series of NH4 concentration in a wastewater system (with NAs)|\n| tsNH4Complete    |Time series of NH4 concentration in a wastewater system (complete)| \n\n  \u003e The tsAirgap, tsHeating and tsNH4 time series are with NAs. Their **complete** versions are\n  \u003e without NAs. Except the missing values their versions are identical.\n  \u003e The NAs for the time series were artifically inserted by simulating the missing\n  \u003e data pattern observed in similar non-complete time series from the same domain.\n  \u003e Having a complete and incomplete version of the same dataset is useful for\n  \u003e conducting experiments of imputation functions.\n \n  More detailed information about the datasets can be found in the [imputeTS reference manual].\n\n## Reference\nYou can cite imputeTS the following: \n\n  \u003e Moritz, Steffen, and Bartz-Beielstein, Thomas. \"imputeTS: Time Series Missing Value Imputation in R.\" R Journal 9.1 (2017). doi: 10.32614/RJ-2017-009.\n \n\n## Need Help?\nIf you have general programming problems or need help using the package please ask your question on [StackOverflow].
