Is the what you are after: > df<-data.frame(cbind("country"=c(rep("Angola", 9), rep("Burundi", 7), + rep("Chad", 13)), "year"=c(1975:1983, 1989:1995, 1965:1977)), + "war"=c(rep(1,2), rep(0,5), rep(1,2), rep(1,2), rep(0,2), rep(1,3), + rep(1,4), rep(0,6), rep(1,3))) > x <- split(df,

[R] Data Frame Manipulation: Time Series

Dear R Helpers: I have a data set where the unit of observation is country-year. I would like to generate a new data set based on some inclusionary (exclusionary) criteria. Here is an example of the type of data that I have. df<-data.frame(cbind("country"=c(rep("Angola", 9), rep("Burundi", 7),
