Read and filter data from the CAPES Catalog of Theses and Dissertations — read_capes_data • capesR

This function combines data from multiple Parquet files and applies optional filters, including text-based searches.

Usage

read_capes_data(files, filters = list())

ler_dados_capes(files, filters = list())

Arguments

files: A vector or list of paths to Parquet files.
filters: A named list of filters. Values for the text columns `titulo` and `resumo` (or `title`/`abstract`) are matched as case-insensitive substrings, and a vector of terms keeps the rows containing any of them (e.g., `list(titulo = c("varicela", "catapora"))`); all other columns are matched exactly (e.g., `list(ano_base = 1987, uf = "SP", titulo = "educação")`).

Value

A `data.frame` containing the combined and filtered data.
