R Help:
I have read a number of tables into R with identical headings and I
would now like to make a single table that has all the data appended
under this single heading line.
for example:
t1 - read.csv(f1,header=TRUE)
t2 - read.csv(f2,header=TRUE)
all - c(t1,t2)
#all is now twice as
?rbind

Does rbind() do what you want?

Dear R users:
append(1:5, 0:1, after=2)
[1] 1 2 0 1 3 4 5
If I want to repeat the appended value every 2 like the following:
[1] 1 2 0 1 3 4 0 1 5
How should I modify?
Thank you for any help.

Here is a way:
x - 1:10
mySeq - c(42,42)
byTwo - rep(seq(length(x) + 1), each=2)[1:length(x)]
y - lapply(split(x, byTwo), function(a){
c(a, mySeq)
})
unlist(y)

If I want to
append does not take a vector the after= argument. Its
probably easiest to just use a loop:
x - 1:5
for(i in c(4,2)) x - append(x, 0:1, after = i)
Note that they need to be inserted in reverse order.

PLEASE do read the posting guide!
Using append=TRUE in write.table only appends rows (see example below).
