You want the merge function. Since your column names that you want to match on already have the same name you don’t even need to do anything special. If that wasn’t the case you would want to look into the by.x and by.y parameters that merge takes. df1 = data.frame(Site.1=c(“A”,”A”,”B”),Site.2=c(“B”,”C”,”C”),Score1=c(60,70,80)) df2 = data.frame(Site.1=c(“B”,”A”,”A”),Site.2=c(“C”,”B”,”C”), Score2=c(10,20,30)) df3 … Read more
