[R] Subsetting dataframe by the nearest values of a vector elements

[Harun Rashid]

Hello,
I have a dataset with two columns 1. cross_section (range: 0~635), and 
2. elevation. The dataset has more than 100 rows. Now I want to make a 
subset on the condition that the 'cross_section' column will pick up the 
nearest cell from another vector (say 0, 50,100,150,200,.....,650).
How can I do this? I would really appreciate a solution.
Regards,
Harun
