import_df() imports a dataframe from a file. The file format can be CSV,
TSV, TXT, RDA, RDS, XLSX, or Parquet format. It recognizes the file format,
reads it and returns it as a tibble.
Examples
# Save a dataframe as an RDA file
save_df(example_metadata, "metadata", "my_data", file_type = "rda")
# Import the saved RDA file again as a tibble
import_df("my_data/metadata.rda")
#> # A tibble: 586 × 9
