From 881a9003031bce222636e165c8124e81360b6343 Mon Sep 17 00:00:00 2001 From: Garrett Grolemund <garrett@rstudio.com> Date: Wed, 3 May 2017 08:44:34 -0400 Subject: [PATCH] Two changes suggested by Toshi (#550) 1. Adds a select() call when exploring diamonds sizes to ensure that the anomalous y variable appears on the page of the printed book (where it is discussed). 2. Adds message = FALSE to suppress "Loading required package: methods" message. --- EDA.Rmd | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/EDA.Rmd b/EDA.Rmd index 7fd255f..4092cf0 100644 --- a/EDA.Rmd +++ b/EDA.Rmd @@ -190,6 +190,7 @@ old <- options(tibble.print_max = 10, tibble.print_min = 10) ```{r} unusual <- diamonds %>% filter(y < 3 | y > 20) %>% + select(price, x, y, z) %>% arrange(y) unusual ``` @@ -458,7 +459,7 @@ But using transparency can be challenging for very large datasets. Another solut `geom_bin2d()` and `geom_hex()` divide the coordinate plane into 2d bins and then use a fill color to display how many points fall into each bin. `geom_bin2d()` creates rectangular bins. `geom_hex()` creates hexagonal bins. You will need to install the hexbin package to use `geom_hex()`. -```{r, fig.asp = 1, out.width = "50%", fig.align = "default"} +```{r, fig.asp = 1, out.width = "50%", fig.align = "default", message = FALSE} ggplot(data = smaller) + geom_bin2d(mapping = aes(x = carat, y = price))
