Ok, merging in this way the total number of rows of the new dataset is the
number of rows of the dataset "request".
Is it possible to obtain a new dataset with the number of rows of the
dataset "phone"?

You wont lose rows, don't worry.
Two notes: merge uses the common columns in both data.frames, so by.x and
by.y aren't
really needed but they wont hurt.
And second, from the help page for 'attach', "attach can lead to confusion.

Is it correct? Coz I'm very frightened to lose datas or make mistakes

With the sample data and the merge as above,
table(res2$phone)
454 2123 2342 9876 56775 87678
2 2 3 3 4 1
with(res2, table(name, request))

t;drink", "food", "paper"), class = "factor")), .Names = c("name",
"request"), class = "data.frame", row.names = c(NA, -15L))
mydata <- merge(dat1, dat2)

Hi Ruri, sorry for my vagueness. The problem is not the order.
I tried to merge the datasets as you wrote. The result is that when I input:
table(phone)
The output is:
0
And this happens for all the variables.

Hello,
What doesn't work, exactly?
I can only see two things:
1. The order of the columns is different, first data.frame in merge
instruction comes first.
Solution: reverse the order of data.frames in merge.
2. The order of the rows is different, the merge function orders it's output
by the c
it doesn't work.
Find attached what I need explained in xls.
Thank you very very much!
