estim_ncpFAMD error

[hathaiphat vongthaiwan]

When I used this command in R

data(ozone)

result_ozone_test <- estim_ncpFAMD(ozone, method = "Regularized", method.cv = "loo")

I got this error

Error in if (!any(summary(jeuNA[, j] == 0))) { : missing value where TRUE/FALSE needed In addition: Warning message: In any(summary(jeuNA[, j] == 0)) : coercing argument of type 'character' to logical

How can I solve this problem? Which point is not correct?

When you read the data, be sure that you have a data-frame and not a tibble. Else do:
MyData <- as.data.frame(MyData)

I add 1 line for changing my data into dataframe as you suggested already before use estim_ncpFAMD() like this.

MyData <- as.data.frame(MyData) 
result <- estim_ncpFAMD(MyData) 

Afterthat, I use estim_ncpFAMD in next line in default, I got the result, but when I add method.cv (cross validation) is loo, It's not working and appear this error again.

result <- estim_ncpFAMD(MyData, method.cv = "loo")

Error in if (!any(summary(jeuNA[, j] == 0))) { : missing value where TRUE/FALSE needed In addition: Warning message: In any(summary(jeuNA[, j] == 0)) : coercing argument of type 'character' to logical

   
It means method.cv = loo is not suitable with missing data or NA in my data? 

I try to check class and type of myData using class(MyData) and typeof(MyData), it shows data.frame for class() and list for typeof()
