[R] Logic operators...more than one??

[David Doyle]

I'm sure this is a simple question but I'm not sure where to find the
answer.

I want to remove some of the data.  For example when my Location column is
MW-09, MW-10, or MW-11.

It works fine if I ONLY list ONE of the locations as in:

SampledWells <- MyData[ MyData$Location != "MW-09", ]

But if I try to do more than one (as shown below), I don't get an error but
I also don't get my SampledWells
SampledWells <- MyData[ MyData$Location != "MW-09", "MW-10", ]

Thoughts??

Thank you for your time
David
