Read Epi Info Data Files
Description
Reads data files in the .REC format used by Epi Info versions 6
and earlier and by EpiData. Epi Info is a public domain database and
statistics package produced by the US Centers for Disease Control
and EpiData is a freely available data entry and validation system.
Usage
read.epiinfo(file, read.deleted = FALSE, guess.broken.dates = FALSE,
thisyear = NULL, lower.case.names = FALSE)
Arguments
file |
A filename, URL, or connection. |
read.deleted |
Deleted records are read if |
guess.broken.dates |
Attempt to convert dates with 0 or 2 digit year information (see ‘Details’). |
thisyear |
A 4-digit year to use for dates with no year. Defaults to the current year. |
lower.case.names |
Convert variable names to lowercase? |
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.
