Description

Trim NAs from the start and end of a time series object.

Usage

trimNA(x, startNAs=TRUE, endNAs=TRUE)
    # S3 method for default
trimNA(x, startNAs=TRUE, endNAs=TRUE)

Arguments

x

A time series matrix or an object of class TSdata.

startNAs

If FALSE then beginning NAs are not trimmed.

endNAs

If FALSE then ending NAs are not trimmed.

Value

A time series object which is windowed to the subset of data which is not NAs (usually the available data).
