?merge maybe is what you want.

Dear r-users,
Suppose I have two data sets
data set-1
Date height
1/11/2005 10
2/11/2005 23
3/11/2005 54
4/11/2005 21
5/11/2005 22
data set-2
weight
merge(data.set.1, data.set.2)
but how do I know which rows to drop in ds1?
if data.set.2 had dates, you could say
merge(data.set.1, data.set.2, by.x=Date, by.y=Date, all=T)
or do you just want to drop the first
length(data.set.1)-length(data.set.2) from data.set.1?
do you have NA values?
Hi Arun,
so to clarify: you want to drop the first
length(data.set.1)-length(data.set.2)
rows... so you might say...
new.ds1 - data.set.1[(-(length(data.set.1)-length(data.set.2)),]
and then add a new column...
new.ds.combined - cbind(new.ds1, data.set.2)
cheers,
Sean

Dear Fernando
Please read the posting guide. If you want to get an answer to your question
you need to be specific about your analysis, and provide examples of the
data structure and code that you tried and didn't work.

hello there,
I'm a new user to R and I am having difficulty reading a
file
If your working directory contains a file you want to read then the
following should work:
dat - read.table(filename.txt)
If you want to use absolute paths, you have to be careful with the '\'
because that is an escape character... so try:
dat -
See the rw-FAQ Q2.14 R can't find my file, but I know it is there!
I'd be interested to know why you didn't find that -- the posting guide
does ask you to read the rw-FAQ, so I presume there is connection that is
not obvious to you.
