Hi,
I need to compare two matrices with each other. If you can get one of
them out of the other one by resorting the rows and/or the columns, then
both of them are equal, otherwise they're not. A matrix could look like
this:
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8]
[1,]011
3 -none- list
d 2 -none- list
e 5 -none- list

Thanks, that was the solution! But in fact I didn't want to have this
"list of lists" layer at all. And now I'm having trouble writing
matrices into the database. It's really really strange... If I write a
matrix into the database manually everything works, but if I create a
function which add
This works, but then I can only save a single matrix in each
database[x,y] while I need to save a list of matrices.
