determining name of object loaded in R

Question

Imagine you have an object foo that you saved as saved.file.rda as follows:

foo <- \'a\'
save(foo, file=\'saved.file.rda\')
<         


        

Answer 1

As you can read in ?load you can load data to specified environment. Then you could use get and ls to get what you want:

tmp_env <- new.env()
load('saved.file.rda', tmp_env)
get(ls(tmp_env), envir=tmp_env) # it returns only first object in environment
# [1] "a"
