Uses linear interpolation for non-seasonal series and a periodic stl
decomposition with seasonal series to replace missing values.

na.interp(x, lambda = NULL)

## Arguments

x |
time series |

lambda |
Box-Cox decomposition parameter. If `NULL` , no transformation
is used. If `lambda="auto"` , a transformation is automatically selected. If
lambda takes a numerical value, it is used as the parameter of the Box-Cox transformation. |

## Value

Time series

## Details

A more general and flexible approach is available using `na.approx`

in
the `zoo`

package.
