I'm not sure I completely understand your question, but I think the
solution
to your problem is the reshape function in the reshape package.
Except there is no reshape function in the reshape package. Your code
works because the reshape function is in the stats package which is
loaded by default.
Here is a
silly example of how it would work:
V<-matrix(rbinom(15,4,.5),nrow=3)
X<-data.frame(A=c("A","B","C"),V=V)
X
A V.1 V.2 V.3 V.4 V.5
1 A 1 2 3 3 3
2 B 4 3 0 2 2
3 C 2 3 2 1 2
reshape(X,direction="long",varying=c("V.1","V.2","V.3","V.4","V.5"))
A time V id
1.1 A 1 1 1
2.1 B 1 4 2
3.1 C 1 2 3
1.2 A 2 2 1
2.2 B 2 3 2
3.2 C 2 3 3
1.3 A 3 3 1
2.3 B 3 0 2
3.3 C 3 2 3
1.4 A 4 3 1
2.4 B 4 2 2
3.4 C 4 1 3
1.5 A 5 3 1
2.5 B 5 2 2
3.5 C 5 2 3
Your two columns of interest are A and V. The time column lets you
know
from which column the V came.

Hi every one Im new to R and I cant figure our how to use the loop
to do
the
following task, any help would be very kind of every one.
I have a file called (table3.txt) that contains over 1000 row and
over 40
columns.
So for example first row would look like that
Deafness, EYA4, DIAPH1, MYO7A, TECTA, COL11A2,
POU4F3,
MYH9, ACTG1,
MYO6
I want the loop stamens to loop thro each row and take first cell
which is
(Deafness and second which is EYA4) and but it on the button of the
file
and
then take the first cell which is (Deafness again and the third
cell which
is the DIAPH1) and put it on the button of the file. And so on till
I end
up
with two columns one consists all the disease and one consist all the
genes.
