Hi,
How to turn a character string into an unevaluated R object? I want to load
some files in a directory into data matrix R objects. I could do this with
read.table and assign (see below). Then, I want to turn the character string
representing a file name (the evaluated expression of i) into an unevaluated R
object. Basically, I want to create matrices whose names are the same as the
related file names.
I don't understand what you mean by an "unevaluated R object". The code
you give below looks as though it would do the rest of what you
describe; what goes wrong with it?

----------------------------
suppose I have
mat1, mat2, mat3 files
v = list.files(".", all.files = F, pattern = "mat")
for (i in v)
assign(i, read.table(i, sep = "\t"), pos = 1)
I would leave off "pos = 1" here, though it should be harmless. It will
only make a difference if you execute this code inside a function or
other local environment.

then, I want to have 3 objects with the names mat1, mat2, mat3 containing what
mat1, mat2, mat3 files contain.
