Hi,
I have a dataset which has both numeric and character values with
dupllicates. For example:
155 A
138 A
138 B
126 C
126 D
123 A
103 A
103 B
143 D
111 C
111 D
156 C
How can I count the number of unqiue entries without counting duplicate
entries. Also can I extract the list in a object. What I mean is
Col1 unique count = 8 Unique Elements are : 103,111,123,126,138,143,155,156
Col2 unique count = 4 Unique Elements are : A,B,C,D.
Any pointers would be of great help.
TIA
Sachin
