Dear list,
This may sound silly. What is the right way to change the names of a
dataframe? Let's say I have this data frame (dose) with four columns with
names "ID", "DOSE", "TIME" "CMT". I want to change "DOSE" to "AMT". So I did
names(dose[2])<-'AMT'
But nothing happened. The name of the second column is still "DOSE".
Only this works
names(dose)[2]<-'AMT'
I wonder what is wrong with the first method. Thanks.
