Average repeated lines

People,

I have a data.frame as follows 

Gene              12h        10d         6w

Slc39a10         1.52      -6.72     -1.84
Slc39a10         1.52      -6.72     -1.84
Mfsd6           -0.15      0.672      0.26
Mfsd6           -2.55     -54.53     -23.75
Hecw2            2.13      2.71       1.92
Hecw2           -7.30     -4.34      -6.49

I wanted to take the average of these repeated values, but keep the line. It would look like this: 

Gene              12h        10d         6w

Slc39a10         media     media      media

Mfsd6            media     media      media

Hecw2            media     media      media

Does anyone know how to solve it?

Using the dplyr package, you can use the group_by (which will group by genes) and summarise_all functions (which will summarize all columns according to a predetermined function). 

library(dplyr)
dados %>% 
  group_by(Gene) %>% 
  summarise_all(mean)
