lininterpol - linearly interpolate values in a vector with NAs

Description

lininterpol - linearly interpolate values in a vector with NAs. A common problem when plotting up time series is where there are missing values or NAs the plotted line will have gaps, one can always plot points on top of a line to identify where there are missing values but an alternative would be to interpolate the missing values linearly and plot that line as a dashed line. This function generates those linear interpolations. The input vector cannot have missing values at the beginning or the end. If there are no missing values the original vector is returned

Usage

lininterpol(invect)

Arguments

invect

the vector of values including missing values

Value

invect but with NAs replaced with linearly interpolated values.
