Usage

gc_smooth.spline(x, y = NULL, ..., na.rm = TRUE)

Arguments

x

y

A vector giving the values of the response variable. If y is missing or NULL, the responses are assumed to be specified by x, with x the index vector.

Value

Similar to stats::smooth.spline, an object of class "smooth.spline" with many components. Differs in that x, y, and w have NA's at any indices where x or y were NA in the inputs, and x, y, and w are returned to match the input x in order and length
