¡Hola! 😄

En esta charla vamos a aprender como visualizar datos con ggplot2

2 / 26

¿ Porque la visualización de datos es importante ?

3 / 26

¿ Porque la visualización de datos es importante ?

  • Manera universal de comunicar información

  • Dar un mensaje claro y eficaz.

  • Encuentra patrones, tendencias, detecta valores extremos.

  • Haga que los datos sean memorables

  • Mantener el interés de la audiencia

¿Qué hace una buena visualización? 🤔

4 / 26

¿Qué hace una buena visualización? 🤔

  • Revela una tendencia o relación entre variables

  • Siempre tenga como mínimo un título, eje, escalas y símbolos

  • Símbolos distintos y legibles (es decir, use contraste)

  • El título debe transmitir la mayor cantidad de información posible

  • Sin ruido: mantenga la información al mínimo

  • el tipo de gráfico correcto según el tipo de datos que se presentarán

Los mapeos estéticos pueden hacer parte de 'ggplot(...)'

paises %>%                           # llama los datos y usamos la tuberia %>%
  ggplot(aes(x=anio, 
             y=esperanza_de_vida)) + # mapeos estéticos y añade capas elementos con +
  geom_line(color="blue") +          # Usa una geom para representar los datos 
  xlab("Anio") +                     # titulo del eje x
  ylab("Esperanza de vida")          # titulo del eje y

  • Datos: siempre una tabla.

  • mapeos estéticos asocian los elementos representables gráficamente (la posición x e y que son dos columnas de la tabla de datos)

  • capas geometrías (geom): puntos, rectas, histogramas, densidades, etc. También se llaman capas porque pueden superponerse.

  • siempre usa el elemento "+" par añadir capas con ggplot (que no se confunden con la tuberia %>%)
