By default, RapidMiner looks for semicolons as attribute separators in our data. We must
change the column separation delimiter to be Comma, in order to be able to see each
attribute separated correctly.
Note:
If your data naturally contain commas, then you
should be careful as you are collecting or collating your data to use a delimiter that does
not naturally occur in the data. A semicolon or a pipe (|) symbol can often help you avoid
unintended column separation.

with the Comma option selected.

Once the preview shows columns for each attribute, click Next. Note that RapidMiner has
treated our attribute names as if they are our first row of data, or in other words, our first
observation. To fix this, click the Annotation dropdown box next to this row and set it to
Name
, as indicated in Figure 3-17. With the attribute names designated correctly, click
Next.
