[R] Need help in function itemFrequency() function - Apriori Algorithm

[santoshdvn]

Hi ,

I am trying the to implement Apriori algorithm with a sample data set . 

 i am trying to find the itemFrequency of the items in the data set . but i
am getting the error as below . i load the data from excel and save the
dataset in "mydata"

*> itemFrequency(mydata)
Error in function (classes, fdef, mtable)  : 
  unable to find an inherited method for function "itemFrequency", for
signature "data.frame"*




*Here is the sample data set .*
17,13,14,16,4,9,14,1,13,0,11,13,5,7,1,4,11,5,
