Reducción tamaño de gráficos en PDF
Buenas tardes a todos,
Estoy interesado en realizar varios gráficos y luego guardarlos
individualmente como PDF. Hasta ahí todo bien. Sin embargo, el archivo
resultante tiene aproximadamente 20MB. Podría alguien por favor indicarme
cómo reducir su tamaño? A continuación un ejemplo de lo que intento hacer
y mi sessionInfo(). Estoy usando Mac OS X.
Muchas gracias,
Jorge Ivan Velez
