Error in do_one(nmeth) : NA/NaN/Inf in foreign function call (arg 1)

Question

I have a data table ("norm") containing numeric - at least to what I can see - normalized values of the following form:

When I am executing

k <- kmeans(norm,center=3) 

I am receving the following error:

Error in do_one(nmeth) : NA/NaN/Inf in foreign function call (arg 1) 

Can you help me? Thank you!

Answer 1

kmeans cannot handle data that has NA values.

The mean and variance are then no longer well defined, and you don't know anymore which center is closest.
