Haven

Haven allows you to load foreign data formats (SAS, SPSS and Stata) in to R by wrapping the fantastic ReadStat C library written by Evan Miller. Haven offers similar functionality to the base foreign package but:

• It reads SPSS files (.dta and .por), reads Stata 13 and 14 files (foreign only works up to Stata 12), and SAS's proprietary binary format (SAS7BDAT + SAS7BCAT). It does not support many of the now more exotic formats supported by foreign.

• Can also write SPSS, Stata, and SAS files.

• Date times are converted to corresponding R classes and labelled vectors are returned as a new labelled class. You can easily coerce to factors or replace labelled values with missings as appropriate. All functions return tibbles.

• Uses underscores instead of dots ;)

Haven is still a work in progress so please file an issue if it fails to correctly load a file that you're interested in.
