Hello,

I am a new user of R and I am trying to use the data I am reading from a spreadsheet.
I installed the xlsReadWrite package and I am able to read data from this files, but how can I assign the colums into values?
E.g:
as I read a spreadsheet like this one:
A B
1 2
4 9

I manually assign the values:
A<-c(1,4)
B<-c(2,9)

to plot it on a graph:
plot(A,B)

or make histograms:
hist(A)

But actualy I am using very large colums, does exist any other way to do it automatically?

Best Regards,

Lämarão
