The case in the analysis is the Brazilian Digital Library of Theses and Dissertations (BDTD). From the almost 670,000 records of BDTD, one applies statistical methods using the language R. One of the visualization packages of R is called Shiny, which makes it easy to build interactive web applications straight from R. Through the app, a user can visualize data in a fast and customizable way. It could help to keep track of metadata and usage statistics over the repositories and also can be applied to discovering scientific information, such as bibliographic data and lists of specialists in a certain research domain. These data visualization tools can stimulate others to create open repositories and join either national, regional or international repositories networks.<\/jats:p>","DOI":"10.3390\/publications8020024","type":"journal-article","created":{"date-parts":[[2020,5,4]],"date-time":"2020-05-04T03:29:39Z","timestamp":1588562979000},"page":"24","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["R-Shiny as an Interface for Data Visualization and Data Analysis on the Brazilian Digital Library of Theses and Dissertations (BDTD)"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1175-5762","authenticated-orcid":false,"given":"Lucca de Farias","family":"Ramalho","sequence":"first","affiliation":[{"name":"Brazilian Institute of Information in Science and Technology (IBICT), SAUS Quadra 5\u2014Lote 6, Bloco H, Bras\u00edlia 70070-912, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3635-9384","authenticated-orcid":false,"given":"Washington R. de Carvalho","family":"Segundo","sequence":"additional","affiliation":[{"name":"Brazilian Institute of Information in Science and Technology (IBICT), SAUS Quadra 5\u2014Lote 6, Bloco H, Bras\u00edlia 70070-912, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,2]]},"reference":[{"key":"ref_1","unstructured":"Carvalho-Segundo, W., Cabezas, A., Matas, L., Amaro, B., and Gomes, G.
