[R] R intersect()

[chalabi.elahe at yahoo.de]

Hi all,
I have the following df:


    licenseY      :int  41006 41013 41044 41046 41067 41166 41202 41262 41274 41290
    licenseZ      :int  41006 41013 41018 41044 41046 41067 41111 41200 41262 41272
I needed the common values in both license columns so I used :
    

    intersect(df$licenseY,df$licenseZ)
now I want a command to return me values from licenseY that are not in intersect(). Does anyone know how should I do this?
Thanks for any help!
