Hello,
There's a typo in your call to mlogit.data, it should be
alt.var="nbChev", not alt.var="noChev".
Then the error is different. You should check the call arguments to see
if they make sense.
Hope this helps,

Can someone explain the error below?

Looks like you need to pay attention to how you read in your data. In general,
you should always execute one statement at a time until you know your script is
working. All the errors after the first one are unhelpful to you or us.
If you actually pay attention to what is in your horse.data data frame after you have read it in,
the columns did not get separated out. The "csv" in in read.csv stands for
"comma", and your file appears to use semicolons. Read the help for read.csv using
?read.csv
and use the sep=";" argument. You should always use the str() function to look
at your data and make sure it looks reasonable before you start trying to give it to
other functions to analyze.
Or use read.csv2 which exists for that reason. (It may be "c" for comma, but in
locales that use comma as the decimal point it is replaced by the semicolon, as you'll
find out if you save an Excel file as CSV in, say, France. This is due to some idiotic
decisions from early 1990s, but there you are...)
Idiotic? In Portugal that is also true and it "allows" us to use the
comma as a decimals marker, as you've said. I would use it, with or
without someone else's decision.
