Hi there, as a newbie in R I have a question on the plm package for panel data:
How do I actually manage to get data into the pdata.frame format? i.e. how do I declare id and time? I already tried various things and got even more error messages. for example > country <- > c("AGO","BWA","DRC","LSO","MDG","MWI","MUS","MOZ","NAM","SYC","ZAF","SWZ","TZA","ZMB","ZWE") > time1 <- c(1991:2006) > pdata.frame(EMPR1,id=country,time=time1) serie SYC is NA and has been removed Fehler in (function(x, i) if (is.matrix(i)) as.matrix(x)[[i]] else .subset2(x, : rekursives Indizieren auf Level 2 fehlgeschlagen where EMPR is a data.frame with 16 rows (time) and 15 columns (countries).
