try with merge() :

table1 = data.frame(	CGID=c("CG_1","CG_3","CG_2", "CG_4", "CG_5"),

table2 = data.frame(	CGID=c("CG_2","CG_3","CG_4", "CG_1", "CG_5"),

newtable <- merge(table1, table2, by="CGID")

matplot(merge(table1, table2, by="CGID")[,2:3])

or reshape() it :

newtable2 <- reshape(newtable,


plot(diff ~ CGID, newtable2)        # if a good number of points
stripplot(diff ~ CGID, newtable2) # if only two per CGID level
