Any help will b
Dear Listmembers
Thank you for your help in resolving the duplicate row.names error. The

Dear List
I am trying to fit a multinomial model using the mlogit package. Attempting to
load
the data into mlogit presents the following error.
MLOG<-mlogit.data(Mult3,shape="long",choice="CHOICE",alt.var="mode.ids",indivs
= "set3",chid.var = "obs")
Error in `row.names<-.data.frame`(`*tmp*`, v
but this should have been detected at the data cleaning
stage.
Best wishes
