I repeatedly get an annoying error with the hts() function even for the example in the help.
Any idea what the problem is?
library(hts)
abc <- ts(5 + matrix(sort(rnorm(1000)), ncol = 10, nrow = 100))
colnames(abc) <- c("A10A", "A10B", "A10C", "A20A", "A20B",
"B30A", "B30B", "B30C", "B40A", "B40B")
y <- hts(abc, characters = c(1, 2, 1))
Error:
Error in hts(abc, characters = c(1, 2, 1,)) :
4 arguments passed to .Internal(nchar) which requires 3
