I have two data frames a and b (with more variables). Now I would like to keep all the variables from b and combine a and b together. How should I do? Will appreciate any wise solutions.

Let's say you only want to keep the first two variables in a
. b
contains additional information about the first two variables in a
.
Code below may help:
a <- data.frame("Var1" = 1:5, "Var2" = 1:5, "Var3" = 1:5)
b <- data.frame("Var1" = 6:10, "Var2" = 6:10, "Col3" = 6:10, "Col4" = 6:10)
b <- b[, which(names(b) %in% names(a))]
a <- a[,1:2]
c <- rbind(a,b)
