Lowess loess

WebThe lowess function performs the computations for the LOWESS smoother (see the reference below). lowess returns a an object containing components x and y which give the coordinates of the smooth. The smooth can then be added to a plot of the original points with the function lines. Web2.2 Lowess/Loess in R Note that there are actually two versions of the lowess or loess scatter-diagram smoothing approach implemented in R. The former (lowess) was implemented first, while the latter (loess) is more flexible and powerful. Example of lowess: lowess(x, y, f=2/3, iter=3, delta=.01*diff(range(x))). Where we sup-pose the …
