Hi,
Can someone explain this error below,
I don't understand why the 2 int columns are associated to make a row name

Error in `row.names<-
Doesn't help when you only reply to me. Use reply-all.

I don't know either. Perhaps someone else on the list who uses that
_contributed_ package will know.
Please be aware that it is both possible and preferred that you make
reproducible examples so others can troubleshoot. See any of [1][2][3]

Thank you Peter. Rounding fixed the problem.

Most likely, previous computations have ended up giving slightly different
values of say 0.1. A pragmatic way out is to round to, say, 5 digits before
applying unique. In this particular case, it seems like all numbers are
multiples of 1/30, so another idea could be to multiply by 30, round,

For example, the probability for z1=0.46667, z2=-1 and z3=-1 is 2.752e-13.

Tom:
Recursive partitioning requires a response variable because splitting
criteria are based on node purity/homogeneity (by various criteria) of
the responses.
So why did you not just search on "clustering" (e.g. at rseek.org)?

At least IMHO.

Hello,
I have a question related to recursive partitioning, but I cannot find
an answer, likely because I don't know how to properly word my Google
search query.
All recursive partitioning examples, which I can find, are used for
either classification or regression trees like

Hello,
There's a typo in your call to mlogit.data, it should be
alt.var="nbChev", not alt.var="noChev".
Then the error is different. You should check the call arguments to see
if they make sense.
Hope this helps,

Hi
If this is urgent why do you provide only limited information.
Windows x Linux x Mac?
Installing from CRN, github elsewhere?
Installing from within R or with OS?

The returned values are in the list you assign to test_data, the original x and
y are not modified, i.e the returned value for x will be test_data[[1]] and for
y will be test_data[[2]]. Using the same variable names in the function and
test is perhaps what is leading to confusion.

Hi,
That was very useful information. Thanks.
But still I am not able to get the desired output with updated code.
Kindly help if you have any further thoughts ...
Updated code :

print(y)
x <- x + 1

c() is used for constructing vectors. Or in other words using the method
c(x,y) provides a vector of length 2 (hopefully). Therefore, you are
pushing a single vector to your function and not two arguments as you want.
It should be Logic_fn(x,y) not Logic_fn(c(x,y)).
Furthermore, i would recommend
