Usage

temp_unzip(filename, fun = data.table::fread, ...)

Arguments

filename	The filename of the zip file to be unzipped.
fun	The function to use to read in the resulting unzipped data file.
...	Additional arguments to be passed to fun. Often, this is select to only read in some of the variables.

Details

I stole this function from a StackExchange answer many years ago and have copied it so many times I no longer know where it came from. Every day we offer thanks to the author.
