There is an easy way to count the number of objects in a vector in R.... also known as getting your Freq on.
Suppose you create a vector called myVec with some elements in it, and you want to know the frequency (i.e., the count) of each object.
Simply convert it into a table, and then cast it as.data.frame. The column names are the original vector name (myVec) and Freq.
> myVec <- c="" cat="" dog="" mouse=""> myDF <- as.data.frame="" myvec="" table=""> myDF myVec Freq 1 cat 3 2 dog 1 3 mouse 2 ->->
This also works if your vector is a column of a data frame as well.
