Properties for parameters of statSmooth().
Degree of polynomial for linear regression model.
Level of confidence interval to use.
Maximum number of data-points for LOESS method. If this quantity exceeded random sampling is applied to data.
Smoothing method: lm (Linear Model) or loess (Locally Estimated Scatterplot Smoothing).
Number of points to evaluate smoother at.
To display confidence interval around smooth.
Random seed for LOESS sampling.
The fraction of source points closest to the current point is taken into account for computing a least-squares regression. A sensible value is usually 0.25 to 0.5.
