read_dta: Read and write Stata DTA files.

Description

Currently haven can read and write logical, integer, numeric, character and factors. See labelled for how labelled variables in Stata are handled in R.

Usage

read_dta(file, encoding = NULL)
read_stata(file, encoding = NULL)
write_dta(data, path, version = 14)

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. It must contain at least one new line to be recognised as data (instead of a path).

encoding

The character encoding used for the file. This defaults to the encoding specified in the file, or UTF-8. But older versions of Stata (13 and earlier) did not store the encoding used, and you'll need to specify manually. A commonly used value is "windows-1252".

data

Data frame to write.

path

Path to a file where the data will be written.

version

File version to use. Supports versions 8-14.

Value

A tibble, data frame variant with nice defaults.

Variable labels are stored in the "label" attribute of each variable. It is not printed on the console, but the RStudio viewer will show it.

Examples

Run this code

# NOT RUN {
path <- system.file("examples", "iris.dta", package = "haven")
read_dta(path)

tmp <- tempfile(fileext = ".dta")
write_dta(mtcars, tmp)
read_dta(tmp)
read_stata(tmp)
# }
