na.StructTS

0th

Percentile

Fill NA or specified positions.

Generic function for filling NA values using seasonal Kalman filter.

Keywords
ts
Usage
na.StructTS(object, …)
# S3 method for ts
na.StructTS(object, ..., na.rm = FALSE, maxgap = Inf)
# S3 method for zoo
na.StructTS(object, ..., na.rm = FALSE, maxgap = Inf)
Arguments
object

an object.

other arguments passed to methods.

na.rm

logical. Whether to remove end portions or fill them with NA.

maxgap

Runs of more than maxgap NAs are retained, other NAs are removed and the last occurrence in the resulting series prior to each time point in xout is used as that time point's output value.

Details

Interpolate with seasonal Kalman filter, using StructTS, followed by tsSmooth. The input object should be a regular time series and have a frequency. It is assumed the cycle length is 1.
