## The dataset presents two parallel components without contamination.

## Examples with fishery data
data(fishery)

## some jittering is necessary because duplicated units are not treated:
## this needs to be addressed
X <- X + 10^(-8) * abs(matrix(rnorm(nrow(X)*ncol(X)), ncol=2))
y1 <- X[, ncol(X)]
X1 <- X[, -ncol(X), drop=FALSE]

## Example 2:
## Define some arbitrary weights for the units
we <- sqrt(X1)/sum(sqrt(X1))
## tclustreg required parameters
k <- 2; restrfact <- 50; alpha1 <- 0.04; alpha2 <- 0.01
## Now tclust is run on each combination of mixt and wtrim options
