[R] list matching

[jim holtman]

One thing you might do is to transform the data into a format that is
easier to combine; I like using 'merge':

> mynames=cbind(c('a','b'),c(11,22))
> lst=list(a=c(1,2), b=5)
> mynames
     [,1] [,2]
[1,] "a"  "11"
[2,] "b"  "22"
> lst
$a
[1] 1 2

$b
[1] 5

> mynames.df <- as.data.frame(mynames)
> mynames.df
  V1 V2
1  a 11
2  b 22
> lst.s <- stack(lst)
> lst.s
  values ind
1      1   a
2      2   a
3      5   b
> merge(mynames.df, lst.s, by.x="V1", by.y="ind")
  V1 V2 values
1  a 11      1
2  a 11      2
3  b 22      5
