Exercises on R pour l’art:
18.5.1 Visualizing word frequency
- Our example of plotting text in Section 18.3 used color to visualize the frequency of each character. Extend the example to visualize the frequency of words in a text.
Highlighting word frequency (using
tb from above):
ggplot(tb, aes(x = x, y = y)) + geom_tile(aes(fill = word_freq)) + geom_text(aes(label = char), col = "white", fontface = 1) + scale_fill_continuous(low = "thistle3", high = "darkmagenta", # low = "red3", high = "darkred", # low = "deepskyblue", high = "darkslateblue", guide = "colorbar", na.value = "white") + # coord_equal() + theme_classic()
18.5.2 Creative freedom
- Create and solve your own exercise that involves some sort of creative expression in R.
