I'm doing some string manipulation on a vector of file names, and noticed something curious. When I strsplit the vector, I get a list of character vectors. The list is numbered, as lists are. When I cast that list as a data frame with 'as.data.frame()', the resulting columns have names derived from the original filenames.
Example code is below. My question is, where are these names stored in the list? Are there methods that can access this from the list? Is there a way to preserve them verbatim?
