kruskal test
2 messages · Adriana Škrinárová, Rui Barradas
Hello, That error occurs if you have Inf values in vekkat. Try to see them with finite <- is.finite(vekkat) sum(!finite) If this is not zero, you can fix your test with kruskal.test(wis1[finite] ~ vekkat[finite]) Hope this helps, Rui Barradas Em 10-03-2013 10:37, Adriana ?krin?rov? escreveu:
