Dear Professor King, I double checked this error and in part know why it's occuring. I ran the most current version the Amelia II, AmeliaView from my home computer on R version 2.3.1 and it ran fine, then I installed R version 2.4.0 Patched and installed Amelia II. When I tryed to use AmeliaView with R version 2.4.0 Patched the error message: Error in load.data(, ) : unused argument(s) () (note: this occurs with either the patched or nonpatched version of R 2.4) Again occured and the data refused to load. Therefore something appears to have changed between these two versions of R which prevents the use of the Amelia II GUI. I hope pointing this out proves to be more help, than headache. Thank you for your time and good will. sb On Wed, 01 Nov 2006 16:21:55 -0500 Gary King wrote: can you make sure you have the new version installed and then try again? if you find the error still, can you email it to me and the others at the listserv? then we can track it down. many thanks & best of luck at PSU!
