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

smartbind() will match column names and tolerates missing ones:

library(gtools)
do.call(smartbind,l)
      A  B
row1 10 20
row2 10 20
