Hello
I have the following dataframe :
df <- data.frame(
Country=c("Zimbabwe","Burkina Faso","South Africa","Madagascar","Tanzania",
"Mali","Mozambique","Madagascar","Ghana","Nigeria","Kenya","Burkina Faso",
"South Africa","Tanzania","Kenya","Ethiopia" ) ,
Iso=c("ZW","BF","ZA","MG","TZ","ML","MZ","MG","GH","NG","KE","BF",
"ZA","TZ","KE","ET") ,
Abaco=c(1,0,1,1,0,1,0,0,0,0,1,1,0,0,0,0) ,
Adaptclone= c(0,0,0,0,1,1,1,1,1,1,0,0,0,0,0,0)
)
There is a lot of column like Abaco, Adaptclone,...
I would like to built a dataframe
wich transforms the initial dataframe of 4 columns into a dataframe of 3
columns as the following dataframe
Country Iso Project
Zimbabwe ZW Abaco
South Africa ZA Abaco
Madagascar MG Abaco
Tanzania TZ Adaptclone
Mali ML Abaco
Mali ML Adaptclone
......
Any idea ?
Michel
