fill missing glucose values from continuous glucose monitoring
Description
Generic function for replacing NA values (missing values) with interpolated values, performing linear or cubic spline interpolation of given data points.
Usage
fillgvp(x, method = "linear", n = 4)
Arguments
x |
Data-set with data frame format containing one column: glucose: glucose value of the observation. |
method |
Character value to replace missing values (NAs) by linear interpolation via linear or cubic spline interpolation via cubic, respectively. Default value is linear. |
n |
Numeric value with maximum number of consecutive NAs to fill. Any longer gaps will be left unchanged. Default value is 4. |
Value
A data frame containing glucose values.
