studentlife data in RData format

This is the studentlife dataset, converted from it's original form (hosted at https://studentlife.cs.dartmouth.edu/dataset.html) into a series of R tibbles (which are similar to a data.frame) and stored in the RData format, for compression / speed and ease of use with R. Note, in this RData format the dataset takes up much less space than the original. These tibbles are suitable for use with the studentlife R package https://github.com/frycast/studentlife which is also available on CRAN, but we recommend installing the latest version from GitHub.

本数据集为StudentLife数据集，其源自原始版本（原始版本托管于https://studentlife.cs.dartmouth.edu/dataset.html），现已转换为一系列R语言的tibble（一种与数据框（data.frame）类似的数据结构），并以RData格式存储，以实现压缩存储、提升读取速度，并便于在R语言环境中使用。请注意，本数据集采用RData格式存储，相较于原始版本占用空间大幅减少。这些tibble可适配StudentLife的R语言包（https://github.com/frycast/studentlife），该包同样可在CRAN上获取，但我们推荐从GitHub安装最新版本。数据集引用信息如下：王锐、陈方林、陈振宇、李天星、加布里埃拉·哈拉里、斯蒂芬妮·蒂诺尔、周霞、德洛尔·本-泽夫及安德鲁·T·坎贝尔所著《StudentLife：利用智能手机评估大学生的心理健康、学业表现与行为趋势》，发表于2014年ACM普适计算大会论文集。
