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 and read_xpt() reads SAS transport files (versions 5 and 8). write_xpt() writes SAS transport files (versions 5 and 8).
SPSS: read_sav() reads .sav files and read_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 with as_factor(). Special missing values are preserved. See vignette("semantics") for more details.
Dates and times are converted to R date/time classes. Character vectors are not converted to factors.
# The easiest way to get haven is to install the whole tidyverse:
install.packages("tidyverse")
# Alternatively, install just haven:
install.packages("haven")library(haven)
# SAS
read_sas("mtcars.sas7bdat")
write_xpt(mtcars, "mtcars.xpt")
# SPSS
read_sav("mtcars.sav")
write_sav(mtcars, "mtcars.sav")
# Stata
read_dta("mtcars.dta")
write_dta(mtcars, "mtcars.dta")foreign reads from SAS XPORT, SPSS, and Stata (up to version 12) files.
readstat13 reads from and writes to all Stata file format versions.
sas7bdat reads from SAS7BDAT files.
