Conclusiones

Como se puede escuchar, R es un lenguaje de programación que permite no sólo analizar estadísticas, gráficas, métodos predictivos y otros puntos cuantitativos, sino que también nos permite correr un código musical. Con esto en mente, se entiende que es un programa versátil que da pie a distintos tipos de documentos, análisis y hallazgos.
