There was an extremely small mistake in the download.R code for DATASUS.
The DATASUS files are named things like DOAM2010.DBC. And we define the file_extension via file_extension <- sub(".*\\.", ".", path), which returns ".DBC".
And the code to actually read the data is
if (file_extension == ".dbc") {
dat <- read.dbc(temp)
}
But the file_extension wasn't ".dbc", it was ".DBC", so it just wasn't read, and the dat object didn't exist.

to make all file extensions lowercase.
