Dear list: I have two dataframes, say dat1 and dat2. Each has several variables but 3 of each are common in both, (say v1, v2 and v3). v1 and v2 are factores while v3 is numeric. Now, I need a subset to extract the rows in which v1, v2 and v3 are the same in both dataframes. I tried:
subset(dat1, dat1$v1 %in% dat2$v1 & dat1$v2 %in% dat2$v2 & dat1$v3 %in% dat2$v3) I dont know why, but this is not working as I was expecting. Any suggestion to improve my code?
