interpolate_NAs(data = data, Method = "linear", XandY = TRUE, MinData = 2)

Value

An object of type data table as described in tibble.

Arguments

data

A data frame object created from auto_cleanup.

Method

A character string indicating type of interpolation ("linear" or "spline") as implemented in na.approx.

Examples

# Load example data
data("Pupilex4")

dat <- interpolate_NAs(Pupilex4, Method = "linear",
                       XandY = TRUE, MinData = 2)
