This code assumes the data frame with at least 3 columns, errors will occur
if there will be less than 3 columns.

I need to create a txt file as input for another program using data.frame
values
Variable_name Start End
[1,] a 1 1
[2,] bbb 2 2
[3,] c 3 6
[4,] ddd 7 10
[5,] eee 11 16
the text file should look like below,
if the start and the end is the same, only put the start one in the txt
file.
a 1
bbb 2
c 3-6
ddd 7-10
eee 11-16
