neville

neville(X, Y, resampleRule, [closed='left'], [origin='start_day'], [outputX=false])

X is a strictly increasing vector of temporal type.

Y is a numeric vector of the same length as X.

resampleRule is a string. See the parameter rule of function resample for the optional values.

closed and origin are the same as the parameters closed and origin of function resample.

outputX is a Boolean value indicating whether to output the resampled X. The default value is false.

Resample X based on the specified resampleRule, closed and origin. Perform neville interpolation on Y based on the resampled X.

If outputX is unspecified, return a vector of Y after the interpolation.

If outputX=true, return a tuple where the first element is the vector of resampled X and the second element is a vector of Y after the interpolation.
