Hi all
I have this problem:
In my database .dta, called "data" I have five rows
data<-read.dta("C:\\2_CO_mmobile_ALL_Rid.dta")
# From this database I wuold like to create another
coppie<-c(data[4:length(data)])
but I find this
# Length of original data
length(data[,4])
5 RIGHT!!
# Length of new data
length(coppie[1])
1 WHY??
Thank you all for your help
Paolo Grillo
