假设我们有两个数据集:
化验:
BHID<-c(127,127,127,127,128)
FROM<-c(950,959,960,961,955)
TO<-c(958,960,961,966,969)
Cu<-c(0.3,0.9,2.5,1.2,0.5)
assays<-data.frame(BHID,FROM,TO,Cu)
和光刻:
BHID<-c(125,127,127,127)
FROM<-c(940,949,960,962)
TO<-c(949,960,961,969)
ROCK<-c(1,1,2,3)
litho<-data.frame(BHID,FROM,TO,ROCK)
我想加入这两组,运行算法后的结果是:
BHID FROM TO CU ROCK
125 940 970 - 1
127 949 950 - 1
127 950 958 0.3 1
127 958 959 - 1
127 959 960 0.9 1
127 960 961 2.5 2
127 961 962 1.2 -
127 962 966 1.2 3
127 966 969 - 3
128 955 962 0.5 -
