In fsdaR: Robust Data Analysis Through Monitoring and Dynamic Visualization

##  ISSUE 10
##
##  Fixed 11.05.2022 - ???
##

##  This happens only when run in R CMD check
##  Does not matter with which data set is run. However, it works
##  fine in the examples for carikeplot()!

library(fsdaR)
data(flea)
Y <- as.matrix(flea[, 1:(ncol(flea)-1)])    # select only the numeric variables
rownames(Y) <- 1:nrow(Y)
head(Y)
(out <- tclustIC(Y, whichIC="CLACLA", plot=FALSE, alpha=0.1, nsamp=100))

This is the very first call to the FSDA engine,
it can take some time to initialize it ...
