我有此数据:
IconButton(
icon: Icon(Icons.date_range),
onPressed: _selectDate(context)),
,我想要这样的输出:
df = data.frame(id = c(1,2,3), title = c("Google-Amazon","Amazon-Google-Yahoo","Yahoo-IMDF"), status = c("Open-Open", "Wait-Close-Open", "Close-Open"))
直到现在我一直尝试的是:
id Google Amazon Yahoo IMDF
1 Open Open NA NA
2 Close Wait Open NA
3 NA NA Close Open
那之后我该怎么做?
答案 0 :(得分:1)
一种选择是使用separate_rows
拆分“标题”,“状态”的行,然后执行spread
将其形状从“长”整形为“宽”
library(tidyverse)
df %>%
separate_rows(title, status) %>%
spread(title, status)
# id Amazon Google IMDF Yahoo
#1 1 Open Open <NA> <NA>
#2 2 Wait Close <NA> Open
#3 3 <NA> <NA> Open Close
