> I will use the lca method in the e1071 package. But I get the following
error:

The error means that you are trying to assign a variable of one size to a
variable of another fixed size. An example that recreates it is:
x <- matrix(1:6, nrow=3)
x[1,] <- 1:10
x[1,] cannot be resized from 3 to 10 without affecting the rest of x, so
an error is thrown.
In your example, the jth row of the matrix pas is a different size from
drop(exp(rep(1, nvar) %*% log(mp))).
Since you haven't provided a reproducible example (tut tut, read the
posting guide) you'll have to do the debugging yourself.
To get you started, type traceback() to see where the problem occurs.
Now try options(error=recover), and call the lca function again. Now you
can examine the values of nvar, mp and pas to see what is going wrong.
