datasource {readr}R Documentation

Create a source object.

Description

Create a source object.

Usage

datasource(
  file,
  skip = 0,
  skip_empty_rows = FALSE,
  comment = "",
  skip_quote = TRUE
)

Arguments

file

Either a path to a file, a connection, or literal data (either a single string or a raw vector).

Files ending in .gz, .bz2, .xz, or .zip will be automatically uncompressed. Files starting with http://, https://, ftp://, or ftps:// will be automatically downloaded. Remote gz files can also be automatically downloaded and decompressed.

Literal data is most useful for examples and tests. To be recognised as a path, it must be wrapped with I(), be a string containing at least one new line, or be a vector containing at least one string with a new line.

Using a value of clipboard() will read from the system clipboard.

skip

Number of lines to skip before reading data.

Examples

# Literal csv
datasource("a,b,c\n1,2,3")
datasource(charToRaw("a,b,c\n1,2,3"))

# Strings
datasource(readr_example("mtcars.csv"))
datasource(readr_example("mtcars.csv.bz2"))
datasource(readr_example("mtcars.csv.zip"))
