access that element in dataframe in R

I have a basic question; how can I access the last element of specific column. in Matlab we can use end to call the last element. I wonder how can i do it in R?
let's say: 

df:
V1   V2
1    5
4    6
8    9
10   11

df[3:last_element,]

in matlab => df(3:end,:)

You can try nrow

df[3:nrow(df),]
#  V1 V2
#3  8  9
#4 10 11

Or use tail

tail(df,1) #to get last row

As commented by @thelatemail, if you want to get the rows from 3:last_element using tail

tail(df,-2)
