Reading DATASUS and ANS .dbc files using R

Those interested in conducting research using Brazilian data often come across some unusual file formats used by Brazilian government agencies. One example is the .dbc files used for health data produced by DATASUS and by ANS. These .dbc files are not related to the.dbf files used by FoxPro for instance. In fact, they are just compressed .dbf files.

There is a package in R that can convert these .dbc files into regular .dbf files. This package is named read.dbc. Once you generated the .dbf files, you can use the package foreign and its function read.dbf to import the data into R. This very same package allow you to save the data using Stata .dta format by means of the function write.dta.

The package maptools also has a function to read dbf files named dbf.read, though I have not tried it yet.
