Hi, Petr,
Thanks for answering.
Yes, I do read the file with the "read.xls" command but I do not know how to
read it into an object.
I read the R-into document chapter of objects, but I is still not clear for
me how to transform this kind of data into an object.
Regards,
Lämarao

Subject: Hi: [R] Help Using Spreadsheets
Hi
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:
Maybe with read.xls? Did you read it into an object?
A B
1 2
4 9
I manually assign the values:
A<-c(1,4)
B<-c(2,9)
Why? If you read in to an object (e.g. mydata)
to plot it on a graph:
plot(A,B)
plot(mydata$A, mydata$B)
or make histograms:
hist(A)
hist(mydata$A)
But actualy I am using very large colums, does exist any other way to do
it automatically?
Yes. But before that you shall automatically read some introduction
documentation like R-intro)
Regards
Petr
Best Regards,
