How can I rbind vectors matching their column names?

Question

rbind does not check for column names when binding together vectors:

l = list(row1 = c(10, 20), row2 = c(20, 10))
names(l$row1) = c(\"A\", \"B\")
names(l$row         


        

Answer 1

Why not just rbind(l$row1, l$row2[names(l$row1)]). Also works well for data frames. Note that this will discard columns from l$row2 that don't appear in l$row1.
