Dear all,
I have a question on the shardsplot package:klaR(see the below Example).
Plese tell me the meanings of " logstand <- t((t(logcount) / sdlogcount) *
c(1,2,6,5,5,3))", much more.
Why does this example use "c(1,2,6,5,5,3)" ?
Examples:
# Compute clusters and an Eight Directions Arranged Map for the
# country data. Plotting the result.
data(countries)
logcount <- log(countries[,2:7])
sdlogcount <- apply(logcount, 2, sd)
logstand <- t((t(logcount) / sdlogcount) * c(1,2,6,5,5,3))
cclasses <- cutree(hclust(dist(logstand)), k = 6)
countryEDAM <- EDAM(logstand, classes = cclasses, sa = FALSE,
iter.max = 10, random = FALSE)
plot(countryEDAM, vertices = FALSE, label = TRUE, stck = FALSE)
Sincerely yours,
Mikio
