Thanks for all replies but it is still not what I wanted. Referring to the previous example that I gave, I want that the objects mat1, mat2 and mat3 be created as matrix object. I want to access their value without get() and when I type ls(), I will have
mat1 mat2 mat3 and not only "mat1" "mat2" "mat3" and when I type dim(mat1) I'll get 12 3 for ex what I'm looking for is the inverse of deparse(substitution()) which gives the name of the object from the object. I want to access the value of the object directly not through its name.
