[R] Newbie in R: Reading .txt files and storing the 'numbers' in a vector

[1Rnwb]

I am also a newbie, but here are the few thing i do
eo=read.table(file="path where you have saved your text
file/xxx.txt",header=T, )   									#this will only read excelfiles saved
as *.csv file
attach(eo)																#attach the data
names(eo)

go to this website http://www.statmethods.net/stats
here is how to store numbers as vectors
a<-c(1,2,3,4,5,6,7)
here is how i means as vector
d<-aggregate(LMMP8,list(PlateID,Self_T1D),mean, na.rm=T)

I would suggest u to search for website for R tutorials
here are some good ones
go to this website http://www.statmethods.net/stats
http://cran.r-project.org/doc/contrib/Lemon-kickstart/kr_ttest.html
this one has all the codes you can change them according to your data
http://www3.imperial.ac.uk/pls/portallive/docs/1/1171930.TXT
