Hi all,
 
I am not a skillful R programmer and has I am handling with large dataframes (about 30000 x 300) I am in need of an efficient function.
 
I have 4 dataframes with the same dimension. I need to generate other dataframe with the some dimension than the others where in each position it has the median value of the 4 values in the same position coming from the 4 dataframes.
 
Grateful by your support,
 
Diogo André Alagador
