在R中拆分多个google表单条目

我有一个csv文件，其中包含一个在线谷歌表单的结果，我正在使用该表单在R中创建图表。表单上有一个问题允许多个响应，人们可以在一个响应中写入。谷歌表单创建CSV的方式是将所有答案放在一行中。以下是几行的示例：

日期 治疗的改变 1/4 开始服用新药，改变剂量 1/5 开始服用新药 1/6 停止用药，开始新的用药，新的诊断 1/7 新诊断

---

下面是一种使用

tidyr:：分隔行的方法：

library(tidyverse)
separated.data <- data %>% 
  separate_rows(Change.in.treatment,sep = ", ")
separated.data
# A tibble: 7 x 2
  Date  Change.in.treatment   
  <chr> <chr>                 
1 1/4   Started new medication
2 1/4   changed dose          
3 1/5   Started new medication
4 1/6   Stopped medication    
5 1/6   Started new medication
6 1/6   New diagnosis         
7 1/7   New diagnosis  


样本数据：

data <- structure(list(Date = c("1/4", "1/5", "1/6", "1/7"), Change.in.treatment = c("Started new medication, changed dose", 
"Started new medication", "Stopped medication, Started new medication, New diagnosis", 
"New diagnosis")), class = "data.frame", row.names = c(NA, -4L
))

数据
data <- structure(list(Date = c("1/4", "1/5", "1/6", "1/7"), Change.in.treatment = c("Started new medication, changed dose", 
"Started new medication", "Stopped medication, Started new medication, New diagnosis", 
"New diagnosis")), class = "data.frame", row.names = c(NA, -4L
))
