[R] Trouble with mixreg

Dear All
I am trying to estimate a mixture of regression and get the following error using the mixreg package:

Error in y - yhat : non-conformable arrays

The instruction I used were:
x <- as.matrix(LRHUN)
y <- as.matrix(LRINTER)

TS <- list(list(beta=c(3.0,1.0),sigsq=1,lambda=0.4),

            list(beta=c(0.0,1.0),sigsq=1,lambda=0.6))

prova <- mixreg(x,y, ncomp=2, theta.start=TS)

The data set has about 1200 observations. I checked out that x and y have the same number of obs. Also examples work fine.

Any hints on what is going on? Thanks
best regards
M
