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