Re: [R] Duplicate row names are not allowed

[peter dalgaard]

Presumably, RCommander's readXL generates an invalid data frame (John?). To 
investigate, look at

row.names(Dataset)

and to fix 

row.names(Dataset) <- NULL

If the issue is that Dataset really isn't a data frame, maybe try Dataset <- 
as.data.frame(Dataset).

[Your screenshot made it through to here, but not the data. Notice, as a 
general matter, that it is preferable to give your code as part of the message 
text; it is hard to copy-paste from a .png]

Re: [R] Duplicate row names are not allowed

Start with the Posting Guide mentioned at the bottom of this email.  Note that 
only a very few types of attachments are permitted on this list... yours 
apparently were not. We generally find that providing a reproducible example 
that includes the data in the R code and the statements that cause difficulty 
all together [1][2][3] conveys questions with as little room for 
misunderstanding as possible.

It does seem like there is something wrong with your data import code  that is 
confusing data that belongs inside the data frame with row names. Just what the 
problem is depends on what code you used to import your data and how that data 
is stored in the file. You need to learn how to use the str function to examine 
your data, and getting us a reprex will help us help you.

[R] Duplicate row names are not allowed

[ville iiskola via R-help]

Hi
I read a book where was shown an example how to create a probability model with 
mlogit. I tried to do like the instruction said but i get error message that 
"duplicate row names are not allowed". What could i do to fix it?

I had the data in excel and imported it to R using R commander. I attach the 
data file and print sqreen of my code to here if somebody could help the 
novice. Ville__
