I need to perform clustering in a given dataset.There are atrributes with numerical as well as categorical values.What is the best way to convert categorical to numeric value ?as an example one field is colour and the values are red, green, blueso can I assign a  mapping like:red : 1, green : 2, blue : 3 orred : 11, green : 25, blue : 30 and if I provide a mapping like this will this affect the Euclidian distance for clustering ?or is there any other way ?
