na.locf

na.locf is replaced by <code>na_locf</code>.
The functionality stays the same. The new name better fits modern R code
style guidelines (which prefer _ over . in function names).

internal

Imputation (replacement) of missing values
in univariate time series.
Offers several imputation functions
and missing data plots.
Available imputation algorithms include:
'Mean', 'LOCF', 'Interpolation',
'Moving Average', 'Seasonal Decomposition',
'Kalman Smoothing on Structural Time Series models',
'Kalman Smoothing on ARIMA models'. Published in Moritz and Bartz-Beielstein (2017)

<dt>maxgap</dt>
<dd>Maximum number of successive NAs to still perform imputation on.

option set, consecutive NAs runs, that are longer than 'maxgap' will
be left NA. This option mostly makes sense if you want to
treat long runs of NA afterwards separately.</dd></dl>
