You do not need to attach 'data', this makes the columns of data
available as objects, which is generally not needed. Just refer to the
columns as data$column_name.

The information in Dataname.csv is now in the object data, see
summary(data) or str(data). Btw, data is also an R function. Redefining
data is not regarded as good programming practice. Furthermore, the use
of the data function (as I've used it) is primarily to load datasets
which have been packaged along side R. As you've already loaded the
dataset using read.csv2, the data(dataname) command is not needed.
It seems to me that, no insult intended, you do not know what you are
doing. I would recommend you either read some more online introductory
material [1], buy some R books, do some kind of R course or find someone
that can tutor you. The kind of assistance you need is hard to give via
a mailing list. Again, I do not mean to be harsh (we where all R noobs
at some stage).
good luck,
Paul
