Save Data Frame or Object to qs File in a Specified Directory with Enhanced Compression

Saves the provided data frame or object as a `.qs` file using the specified name, within a directory defined by `dir_path`. This function leverages the `qs` package to write data to `.qs` format with enhanced compression for efficient storage and quick access in R.

Usage

here_save_qs(obj, name, dir_path, preset = "high", nthreads = 1)

Arguments

obj: Data frame or object to be saved. This is the object you want to persist to disk in `.qs` format.
name: Character string specifying the base name of the file (without the ".qs" extension).
dir_path: Character string specifying the directory path where the file will be saved.
preset: Character string specifying the compression preset. Default is "high" for better compression.
nthreads: Integer specifying the number of threads to use for compression. Default is 1.

Value

Invisible NULL. The primary effect of this function is the side effect of writing a `.qs` file to disk.

Details

The `dir_path` argument must point to an existing directory. The function does not create directories; it assumes that the specified directory already exists. The function uses enhanced compression settings by default to minimize file size.

Examples

my_df <- data.frame(x = 1:5, y = letters[1:5])
here_save_qs(my_df, "my_saved_dataframe", "~/mydata")
#> Error in qs::qsave(obj, file_path, preset = preset, nthreads = nthreads): For file ~/mydata/my_saved_dataframe.qs: Failed to open for writing. Does the directory exist? Do you have file permissions? Is the file name long? (>255 chars)
