fillgvp

Generic function for replacing NA values (missing values) with interpolated values, performing linear or cubic spline interpolation of given data points.

Calculate different glucose variability measures,
including average measures of glycemia, measures of glycemic variability and
measures of glycemic risk, from continuous glucose monitoring data.
