 library(ggplot2)
-ggplot(maps = aes(x = 1:100, y = data) +
-    geom_line(col = "blue") +
-    theme_light()
+ggplot(mapping = aes(x = 1:100, y = data)) +

 Et on peut aussi aisément inclure des figures. Par exemple:
 
 ```{r pressure}
-ggplot(maps = aes(x = data) +
-    geom_histogram(col = "blue") +
+ggplot(mapping = aes(x = data)) +
+    geom_histogram(fill = "blue", col = "black) +
+    labs(x = NULL, y = NULL) +
     theme_light()
 ```
