I am checking the taste data set example of "Taste dataset" on p52 of https://cran.r-project.org/web/packages/soc.ca/soc.ca.pdf
On the csa part, I encounter the error.
options(passive=NULL)
class.age <- which(data_taste$Age == '55-64')
result.csca <- soc.csa(result.mca, class.age, sup)
Error is as following.
colSums(sup) でエラー: 'x' は数値でなければなりません
(Sorry my system is Japanese, so the message is in Japanese. It meas Error at colSums(sup) 'x' have to be numeric. )
I know "sup" is defind at the top of this example script,
sup <- data.frame(data_taste$Gender, data_taste$Age, data_taste$Income)
.
So I expact to pass the "sup" directly and try as next .
result.csca <- soc.csa(result.mca, class.age)
It generate the result. But I am not sure this result is reliable.
How can I do on this issue.
regards.
