Details

Epi Info allows dates to be specified with no year or with a 2 or 4 digits. Dates with four-digit years are always converted to Date class. With the guess.broken.dates option the function will attempt to convert two-digit years using the operating system's default method (see Date) and will use the current year or the thisyear argument for dates with no year information.

If read.deleted is TRUE the "deleted" attribute of the data frame indicates the deleted records.

Value

A data frame.

Note

Some later versions of Epi Info use the Microsoft Access file format to store data. That may be readable with the RODBC package.
