## notes:
data$X[[2]]
The X dataset has been simulated by Gordaliza, García-Escudero & Mayo-Iscar during the Workshop ADVANCES IN ROBUST DATA ANALYSIS AND CLUSTERING held in Ispra on October 21st-25th
2013. It is a bivariate dataset of 200 observations. It presents two parallel components without contamination.

## notes:
data$fishery[[4]]
The fishery data consist of 677 transactions of a fishery product in Europe. For each transaction the Value in 1000 euro and the quantity in Tons are reported.

## notes:
data$wool[[4]]
The wool data give the number of cycles to failure of a worsted yarn under cycles of repeated loading.
The variables are: X1, length of test specimen; X2, amplitude of loading cycle; X3, load

rownames(mussels) <- 1:nrow(mussels)
save(mussels, file="mussels.rda")
## notes:
data$mussels[[1]]
These data, introduced by Cook and Weisberg (1994), consist of 82 observations on horse mussels from
New Zeland. The variables are shell length, width, height, mass and muscle mass
