[julia-users] join dataframe columns

[pip7kids]

Hi
How can I join 2 columns in a dataframe.

e.g.
Dataframe 1

Row    Name       Name2       Amt
1         Test        A               123
2         Test2      B                456
etc

I want to be able to join Name and Name2 and use a separator like -
eg
Row    Name       Amt
1         Test-A     123
2         Test2-B    456

Regards
