我正在尝试合并两个数据框:DF1DF2. 这DF1是我的数据,DF2不是,但它有一些我想添加到我的数据中的变量:变量“flow1”和“flow2”。

数据是二元的,所以我创建二元 ID

DF1 <- within(DF1, ID <- paste(ccode2,ccode1,year)) # assume this order is right
DF2 <- within(DF2, ID <- paste(ccode1,ccode2, year))

合并:

variables <- c("ID", "flow1", "flow2") # flow1 and flow2 are the variables that I want to add to my data. 

DF3<- merge(DF1, DF2[,variables], by=c("ID"), all.x=T) # dec 9 

问题是它并没有真正起作用,但它应该因为我以前做过很多次。

  • 我在这里做错了什么?
