The import
function is a wrapper for the
haven,
readxl, and
vroom packages. The vroom
package provides one of the fastest methods for importing delimited
text files currently available.
Files are imported based on their extension (.sas7bdat
for SAS,
.sav
for SPSS, .dta
for Stata, and .xls
or .xlsx
for Excel). All other file extensions are assumed to
belong to delimited text files (e.g., comma or tab delimited files).
If you import a delimited text file without options, the structure
and delimiters are determined from the first 100 rows.You can override
these guesses by specifying options
(e.g., sep=";", na="999"
).
