Dear R-Helpers,

I have this dataset:

   YEAR    PRODUCTS cluster
    1          10          2
    2          42          3
    3          25          2
    4          42          3
    5          40          3
    6          45          1
    7          44          1
    8          47          1
    9          42          1


I want to create a subset (when cluster=1),

    YEAR    PRODUCTS cluster
    6          45          1
    7          44          1
    8          47          1
    9          42          1


How can i perform this?


Thank you in advance.
