practical way to change column names?
2 messages · Niklas Fischer, PIKAL Petr
Hi
sufix<-expand.grid(c("id","ag"), 1:10)
paste(paste("alter",sufix[,1], sep=""), sufix[,2], sep="_")
shall give you desired names.
After that you can reorganise it to suit your needs.
Regards
Petr

Dear R helpers, I have a social network data including repated measures of ten alters (whom you contact) and their attributes(gender, age, strength of tie). I wrote variables related with alters just for wrote alter 1 and alter 2. I'd like to change the like below. I'd change each name separetely. Do you know any pratical way to change it? All the bests, Niklas variables for alter 1 g61a (id) g62a (gender) g63a (age) g63aa (tie) g63aan (tie friequency) variables for alter 2 g61b g62b g63b g64b g64bb g64bbn new names alterid_1 alterag_1 alteraa_1 alatert_1 altersf_1 alterid_2 alterag_2 alteraa_2 alatert_2 altersf_2 [[alternative HTML version deleted]]
