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.
