smart_read {iNZightTools}

R Documentation

Read a data file

Description

A simple function that imports a file without the users needing to specify information about the file type (see Details for more). The smart_read() function uses the file's extension to determine the appropriate function to read the data. Additionally, characters are converted to factors by default, mostly for compatibility with iNZight (https://inzight.nz).

Usage

smart_read(
  file,
  ext = tools::file_ext(file),
  preview = FALSE,
  column_types = NULL,
  ...
)

Arguments

file	the file path to read
ext	file extension, namely "csv" or "txt"
preview	logical, if TRUE only the first few rows of the data will be returned
column_types	vector of column types (see ?readr::read_csv)
...	additional parameters passed to read_* functions

Details

Currently, smart_read() understands the following file types:

• delimited (.csv, .txt)

• Excel (.xls, .xlsx)

• SPSS (.sav)

• Stata (.dta)

• SAS (.sas7bdat, .xpt)

• R data (.rds)

• JSON (.json)

Value

A dataframe with some additional attributes:

• name is the name of the file

• code contains the tidyverse code used to read the data

• sheets contains names of sheets if 'file' is an Excel file (can be retrieved using the sheets() helper function)
