Hi Jim, Here is one way: # How I imagine your data might be stored l_one - list(structure(list(key = c(2, 1, 2)), .Names = key, row.names = c(NA, -3L), class = data.frame)) l_two - list(structure(list(ndx = 1:4, descr = c(this, that, other, finis)), .Names = c(ndx, descr), row.names = c(NA,

Re: [R] Merge disparate lists

Hi: Is this what you need? l_one - data.frame(key = c(2, 1, 2)) l_two - data.frame(ndx = 1:4, descr = c('this', 'that', 'other', 'finis')) merge(l_one, l_two, by.x = 'key', by.y = 'ndx') key descr 1 1 this 2 2 that 3 2 that HTH, Dennis On Wed, Oct 27, 2010 at 10:53 AM, Jim Burke
