Can someone help me with that?

You are missing a comma. You are addressing the dataframe as if it
were a matrix and you want to extract all the rows that match:

Kiran,
One, not very elegant way, to solve your problem is to first save the
Excel spreadsheet as a CSV file (open the Excel file in Excel and the
use file->save as CSV, i.e. xxx.CSV) and then use read.csv()

I´m a really R beginer,
so I have a simply question.
I would like to rename a vector in a loop.
I´d like to have as output:
vector1<-whatever
vector2<-whatever
vector3<-whatever
etc..
so I thought it´s easily
for (s in c(1:3)){
vector"n"<- whatever
}
but I´m getting an error.

I am trying to get a prediction of my GAM on a response type. So that I

Hi,
R version 2.2.1 is slightly old. You may want to upgrade to the current
version, R.2.8.1!!!
You can for example do
library(doBy)
dd <- data.frame(x=c(1,1,1,2,2,2), y=c(1,1,2, 1,1,1))
summaryBy(y~x, data=dd, FUN=function(x)length(unique(x)))

I agree on the database solution.
Database are the rigth tool to solve this kind of problem.
Only consider the start up cost of setting up the database. This could
be a very time consuming task if someone is not familiar with database
technology.
Using file() is not a real reading of all the f
if the file is really large, reading it twice may add considerable penalty:
