Wrapper function for reading data functions

This function receives a file extension and returns the proper reading function from popular R packages such as: arrow, haven, readxl and utils.

Usage

read_fun(extension, ...)

Arguments

extension: A string specifying the file extension that must support the returned function. Supported extensions: 'parquet', 'feather', 'dta', 'xlsx', 'csv', 'sas', 'rds' and 'rdata'. This parameter is case robust.
...: Additional arguments to be passed to the reading functions encapsulated in read_fun().

Value

A function that can read data from the specified file format. The returned function will accept the file path as its first argument.

Examples

if (FALSE) {
# Read Parquet file
reader <- read_fun("parquet")
data <- reader("file.parquet")

# Read Excel file
reader <- read_fun("xlsx")
data <- reader("file.xlsx")

# Read Parquet file
reader <- read_fun("parquet")
data <- reader("file.parquet")

# Read Excel file
reader <- read_fun("xlsx")
data <- reader("file.xlsx")

# Read CSV file with comma separator
reader <- read_fun("csv", sep = ',')
data <- reader("file.csv")

# Read TXT file with tab separator and specifying additional arguments
reader <- read_fun("txt", sep = '\t', skip = 1, header = FALSE)
data <- reader("file.txt")
