| import_to_fst {wpa} | R Documentation |
Read a Workplace Analytics query in '.csv' using and create a '.fst' file in the same directory for faster reading
Description
Uses import_wpa() to read a Workplace Analytics query in
'.csv' and convert this into the serialized '.csv' format which is much
faster to read. The 'fst' package must be installed, or an error message is
returned.
Usage
import_to_fst(path, ...)
Arguments
path |
String containing the path to the Workplace Analytics query to be
imported. The input file must be a CSV file, and the file extension must be
explicitly entered, e.g. |
... |
Additional arguments to pass to |
Details
The fst package provides a way to serialize
data frames in R which makes loading data much faster than CSV.
import_to_fst() converts a CSV file into a FST file in the specified
directory.
Once this FST file is created, it can be read into R using
fst::read_fst(). Since import_to_fst() only does conversion but not
loading, it should normally only be run once at the beginning of each piece
of analysis, and fst::read_fst() should take over the job of data loading
at the start of your analysis script.
Internally, import_to_fst() uses import_wpa(), and additional arguments
to import_wpa() can be passed with ....
Value
There is no return value. A file with '.fst' extension is written to the same directory where the '.csv' file is read in.
