将多列合并为整洁数据
我的数据集如下所示:
unique.id abx.1 start.1 stop.1 abx.2 start.2 stop.2 abx.3 start.3 stop.3 abx.4 start.4
1 1 Moxi 2014-01-01 2014-01-07 PenG 2014-01-01 2014-01-07 Vanco 2014-01-01 2014-01-07 Moxi 2014-01-01
2 2 Moxi 2014-01-01 2014-01-02 Cipro 2014-01-01 2014-01-02 PenG 2014-01-01 2014-01-02 Vanco 2014-01-01
3 3 Cipro 2014-01-01 2014-01-05 Vanco 2014-01-01 2014-01-05 Cipro 2014-01-01 2014-01-05 Vanco 2014-01-01
4 4 Vanco 2014-01-02 2014-01-03 Cipro 2014-01-02 2014-01-03 Cipro 2014-01-02 2014-01-03 PenG 2014-01-02
5 5 Vanco 2014-01-01 2014-01-02 PenG 2014-01-01 2014-01-02 PenG 2014-01-01 2014-01-02 Cipro 2014-01-01
stop.4 intervention
1 2014-01-07 0
2 2014-01-02 0
3 2014-01-05 1
4 2014-01-03 1
5 2014-01-02 0
用一些代码创建:
abxoptions <- c("Cipro", "Moxi", "PenG", "Vanco")
df3 <- data.frame(
unique.id = 1:5,
abx.1 = sample(abxoptions,5, replace=TRUE),
start.1 = as.Date(c('2014-01-01', '2014-01-01', '2014-01-01', '2014-01-02', '2014-01-01')),
stop.1 = as.Date(c('2014-01-07', '2014-01-02', '2014-01-05', '2014-01-03', '2014-01-02')),
abx.2 = sample(abxoptions,5, replace=TRUE),
start.2 = as.Date(c('2014-01-01', '2014-01-01', '2014-01-01', '2014-01-02', '2014-01-01')),
stop.2 = as.Date(c('2014-01-07', '2014-01-02', '2014-01-05', '2014-01-03', '2014-01-02')),
abx.3 = sample(abxoptions,5, replace=TRUE),
start.3 = as.Date(c('2014-01-01', '2014-01-01', '2014-01-01', '2014-01-02', '2014-01-01')),
stop.3 = as.Date(c('2014-01-07', '2014-01-02', '2014-01-05', '2014-01-03', '2014-01-02')),
abx.4 = sample(abxoptions,5, replace=TRUE),
start.4 = as.Date(c('2014-01-01', '2014-01-01', '2014-01-01', '2014-01-02', '2014-01-01')),
)
以下解决方案无法满足我的需求: 收集多组列并将 多列组合成一列
我怀疑Hadley令人惊奇的tidyr pakcage是要走的路......只是想不出来。任何帮助将不胜感激。
