Hi guys!
I have a vector with a list of words e.g c("victory","happines").
I have a vector of sentence e.g. In "WWII the victory was achived by allied
forces".
As word victory is in my list, victory has a frequency of 1, happines 0.
At the end I wolud like to get 5 most frequent words from my list that appear
in sentences.
Can you help me.
Uros
