I'm trying to find an R package that will smooth a line with the
"polynomial
approximation with exponential kernel" or "PAEK" algorithm that
is used in
ESRI's ArcGIS software. I have a copy of the original paper that provides
the algorithm, but I'm not confident in how to code it. The algorithm will
smooth a polyline's vertices at a user specified distance along the
polyline. The paper refers to this as "smoothing with continuous local
weighted averaging." Ultimately, I want to be able to bring in the X-Y
coordinates of the vertices into R and perform the smoothing.
Limited information on how the algorithm is used in ArcGIS is located here:

The reference to the original paper is:
Bodansky, Eugene; Gribov, Alexander; and Pilouk, Morakot, "Smoothing and
Compression of Lines Obtained by Raster-to-Vector Conversion", LNCS 2390,
Springer, p. 256-265, 2002.
I have a PDF copy of the paper that I can send via email. I appreciate any
information that will help me accomplish smoothing a line with this
algorithm, and/or a comparable one, in R. Thanks.
