Hi All,
I am still learning R, but making, IMO, great strides. I learned about
Kohonen/Self-Organizing Maps in class and I would like to try to replicate some
of the things we have seen in class.
Below is my code. I am trying to create a u-matrix. In the documentation on
page 9 it appears the type of plot, dist.neighbours should do the trick,
however, I am getting an error:
(Error in match.arg(type) : 'arg' should be one of "codes", "changes",
"counts", "mapping", "property", "quality")
Since I am new to R, I figure I am missing something obvious. Any help you can
provide will be greatly appreciated!
Thanks in advance,
Brock

library(kohonen)
data("wines")
wines.sc <- scale(wines)
som <- som(wines.sc, grid=somgrid(5, 5, "hexagonal"))
plot(som)
plot(som, type="dist.neighbours" )
