Hi, Does anybody know how to incorporate panel data into Hoareau et al "*easi*" Package? In Hoareau et al "easi" Package they use cross sectional data and I would like to know how I could include 5 years worth of panel data? Many thanks, Neil -- View this message in context: http://r.789695.n4.nabble.com/The-easi-Package-incorporating-panel-data-tp4674134.html Sent from the R help mailing list archive at Nabble.com.
