Combine two lists in a dataframe in R

Question

I have two lists with different structure:

listA <- list(c(\"a\",\"b\",\"c\"), c(\"d\",\"e\"))
listB <- list(0.05, 0.5)

listA
[[1]]
[1] \"a\" \"b\" \"c\"
         


        

Answer 1

I'd prefer this:

do.call(rbind,
        Map(function(...) setNames(cbind.data.frame(...), 
                                   c("A", "B")), 
            listA, listB))
#  A    B
#1 a 0.05
#2 b 0.05
#3 c 0.05
#4 d 0.50
#5 e 0.50
