read_file: Read files based on the extension

Description

read_file() is the backbone of all read_cnt methods, where files are read from their source. The function is a wrapper around read_ext(), that controls the dispatch based on the file extension.

read_ext() controls which packages and functions are used to read the individual file extensions. Below is a list of all the pre-defined methods:

• default: All extensions not listed below is attempted to be read with vroom::vroom()

• txt: readr::read_lines()

• csv: readr::read_csv()

• parquet: arrow::read_parquet()

• rds: readr::read_rds()

• sas7bdat: haven::read_sas()

• xpt: haven::read_xpt()

• yml/yaml: yaml::read_yaml()

• json: jsonlite::read_json()

• excel: readxl::read_excel()

Usage

read_file(path, ...)
read_ext(path, ...)
# S3 method for default
read_ext(path, ...)
# S3 method for txt
read_ext(path, ...)
# S3 method for csv
read_ext(path, delim = ",", ...)
# S3 method for parquet
read_ext(path, ...)
# S3 method for rds
read_ext(path, ...)
# S3 method for sas7bdat
read_ext(path, ...)
# S3 method for xpt
read_ext(path, ...)
# S3 method for yml
read_ext(path, ...)
# S3 method for json
read_ext(path, ...)
# S3 method for xlsx

Examples

# Read CSV file
