[R] summing up a column.

[PIKAL Petr]

Ok.

Instead of explaining what you have, please send a result of

dput(B) and dput(A)

And set you mail client to send plain text mail otherwise your code is barely readable.

What do you want to do with printed values?

What is B? From this it seems that it is data frame but then you try to put sorted data frame into a data frame column.

B$possort=B[order(B$pos),]

With such code and data frame I get an error.

So please try to keep above mentioned when posting a query.

Regards
Petr
