haven
Overview
Haven enables R to read and write various data formats used by other statistical packages by wrapping the fantastic ReadStat C library written by Evan Miller. Haven is part of the tidyverse. Currently it supports:
SAS:
read_sas()
reads.sas7bdat
+.sas7bcat
files andread_xpt()
reads SAS transport files (version 5 and version 8).SPSS:
read_sav()
reads.sav
files andread_por()
reads the older.por
files.write_sav()
writes.sav
files.Stata:
read_dta()
reads.dta
files (up to version 15).write_dta()
writes.dta
files (versions 8-15).
The output objects:
Are tibbles, which have a better print method for very long and very wide files.
Translate value labels into a new
labelled()
class, which preserves the original semantics and can easily be coerced to factors withas_factor()
. Special missing values are preserved. Seevignette("semantics")
for more details.Dates and times are converted to R date/time classes. Character vectors are not converted to factors.
Installation
# The easiest way to get haven is to install the whole tidyverse:
install.packages("tidyverse")
# Alternatively, install just haven:
install.packages("haven")
Usage
library(haven)
# SAS
read_sas("mtcars.sas7bdat")
write_sas(mtcars, "mtcars.sas7bdat")
# SPSS
read_sav("mtcars.sav")
write_sav(mtcars, "mtcars.sav")
# Stata
read_dta("mtcars.dta")
write_dta(mtcars, "mtcars.dta")
