[R] Howto access V-base only column in a data frame

Suppose I have the following data frame:

 V1 V2 V3 var
1 100 200 400 2.3
2 40.5 1.2 20.3

In this example the maximum V column is 3. In my code there the column number can be varied.

My question is how can I access data frame from column V1 up to Vk (some "k" and excluding'var' column)?
