这是我的输入数据集:
> names(breakingbad.episodes)
[1] "season" "episode" "epnum" "epid" "title"
[6] "url.trakt" "firstaired.utc" "id.tvdb" "rating" "votes"
[11] "loved" "hated" "overview" "firstaired.posix" "year"
[16] "zrating.season" "src"
对于我ggvis,我用下面的变量firstaired.posix和rating:
> str(breakingbad.episodes[c("firstaired.posix", "rating")])
'data.frame': 62 obs. of 2 variables:
$ firstaired.posix: POSIXct, format: "2008-01-21 02:00:00" "2008-01-28 02:00:00" "2008-02- 11 02:00:00" ...
$ rating : num 87 85 84 84 83 90 87 85 88 83 ...
我ggvis使用包含以下rating信息的工具提示成功创建了我:
> breakingbad.episodes %>%
ggvis(x = ~firstaired.posix,
y = …
