How to merge multiple dataframes with a common column? Merge takes only two dataframes as arguments. Something like: df <- merge(df1,df2,df3,...,by="ID")
Is that a unique ID the same values of which occur in all the dfs? Then it is not a question of merging. Sort them all on ID and cbind them. Otherwise you can merge df1 with df2, df12 with df3 etc.
