我有两个大型数据集df1和df2。第一个数据集df1包含列“ID”和“actual.data”。
df1 <- data.frame(ID=c(1,1,1,2,3,4,4), actual.date=c('10/01/1997','2/01/1998','5/01/2002','7/01/1999','9/01/2005','5/01/2006','2/03/2003'));
dcis <- grep('date$',names(df1));
df1[dcis] <- lapply(df1[dcis],as.Date,'%m/%d/%Y');

最佳答案
您可以使用foverlaps
中的data.table
。使用“开始/结束”列将“data.frame”都转换为“data.table”。将键列设置为每个数据集的列名。使用foverlaps
获取数字索引,可以根据其中的NA值将其转换为二进制“匹配”。
library(data.table)#v1.9.5+
dt1 <- data.table(ID=df1$ID, start=df1$actual.date, end=df1$actual.date)
setkeyv(dt1, colnames(dt1))
dt2 <- as.data.table(df2)
setnames(dt2, 2:3, c('start', 'end'))
setkeyv(dt2, colnames(dt2))
indx <- foverlaps(dt1, dt2, type='within', which=TRUE, mult='first')
dt1[, match:= +(!is.na(indx))][,end:=NULL]
setnames(dt1, 1:2, colnames(df1))
dt1
