My data set has 8 variables and one of them is categorical but R thinks that it is integer (0's and 1's). What I have to do inorder to covert it into categorical?
> str(mydata)
'data.frame': 117 obs. of 8 variables:
$ PRICE: int 2050 2080 2150 2150 1999 1900 1800 1560 1450 1449 ...
$ SQFT : int 2650 2600 2664 2921 2580 2580 2774 1920 2150 1710 ...
$ AGE : int 13 NA 6 3 4 4 2 1 NA 1 ...
$ FEATS: int 7 4 5 6 4 4 4 5 4 3 ...
$ NE : int 1 1 1 1 1 1 1 1 1 1 ...
$ CUST : int 1 1 1 1 1 0 0 1 0 1 ...
$ COR : int 0 0 0 0 0 0 0 0 0 0 ...
$ TAX : int 1639 1088 1193 1635 1732 1534 1765 1161 NA 1010 ...
COR should have been categorical.
