Dados das cartas FC04 - C1 a C6 - ALiB

This dataset contains derived and structured linguistic data used in the article “RHOTICS AND THE DIALECTAL CONFIGURATION OF BRAZILIAN PORTUGUESE: FROM NASCENTES TO THE ALIB ”, obtained from the analytical extraction of maps F04 C1–C6 of the Atlas Linguístico do Brasil (ALiB). The data describe the distribution of rhotic segments in syllable coda position, organized by map, grammatical class, phonological context, Brazilian administrative region, and capital city. The dataset distinguishes between maps that indicate only presence or absence of the rhotic segment and those that specify its phonetic realizations. All data are aggregated and non-identifiable. No raw interview data or individual speaker information are included. The dataset enables the reproducibility of the analytical procedures described in the article without re-digitizing cartographic images.
