df1
vec1 vec2 vec3
0     10   5
10    20   13
20    30   28

I would like to create a new column as shown below that contains the median value of a list of vectors in the data frame at its row index.

df1
vec1  vec2 vec3 median
0     10   5    5
10    12   13   12
20    30   28   28

@scoa what if I only want to apply this to vectors 2 and 3? – James H Sep 08 '15 at 21:23

@scoa thanks. I know I will be applying it to several columns that aren't always the first or last in the data frame. I didn't want to stray too much with the question though. This answers everything. – James H Sep 08 '15 at 21:29
