What is cell? And how do you want to "move" data?

BTW. What type of data? Matrix, data frame, vector, list, ...

I can imagine for instance
> mat<-matrix(rnorm(4), 2,2)
> mat
           [,1]      [,2]
[1,] -1.1336516 0.8050537
[2,]  0.9676428 0.9532624
> mat[2,2]<-mat[1,1]
> mat
           [,1]       [,2]
[1,] -1.1336516  0.8050537
[2,]  0.9676428 -1.1336516

But it seems to me that this is not what you want.

Spreadsheets have cells, but R does not. So you will have to be much more
specific.

The closest I can come would be like this example:

If you want to copy the value that is in the 3rd row, 2nd column to the
4th row, 1st column, then
  mydata[4,1] <- mydata[3,2]
But that is a copy, not a move (and whatever was in "cell" 4,1 will be
gone.
To leave the 3rd row, 2nd column "empty", then next you would do
  mydata[3,2] <- NA

However, this example is only a guess, and it only makes sense if your
data is stored in a matrix or data frame. But you haven't said how your
data is stored.

Please read and follow the posting guide, as requested at the bottom of
every message to r-help. You will receive better help if you do. You
should probably also download and read one of the introductory manuals
from CRAN, if you have not already. It will explain many basic concepts.
