Details

Experimental. (Notably, the function's name may change.)

The function reads a (typically multi-line) string and treats each line as one element of a vector or, if sep is specified, a data.frame.

If sep is not specified, here calls type.convert on the input s.

If sep is specified, the input s is fed to read.table. Additional arguments may be passed through ....

Value

a vector or, if sep is specified, a data.frame
