funplot: Plot functional data with linear interpolation of missing values
Description
Plot functional data with linear interpolation of missing values
Usage
funplot(x, y, id = NULL, rug = TRUE, ...)
Arguments
x
optional, time-vector for plotting
y
matrix of functional data with functions in rows and measured times in columns;
or vector or functional observations, in this case id has to be specified
id
defaults to NULL for y matrix, is id-variables for y in long format
rug
logical. Should rugs be plotted? Defaults to TRUE.
All observations are marked by a small cross (pch=3).
Missing values are imputed by linear interpolation. Parts that are
interpolated are plotted by dotted lines, parts with non-missing values as solid lines.
