hi , i have this problem for a week now , first of all i have one node with hadoop and Rstudio in it . when i want to run this program :

ints = to.dfs(1:100) calc = mapreduce(input = ints, map = function(k, v) cbind(v, 2*v)) from.dfs(calc)

first i get this error :

Error in library(functional) : there is no package called ‘functional’

I installed the package , but still gives me the same error , so after reading a lot of discussion about path and that R doesn't know where functional is , i did .libPath() and i copied the package functional in all the directories that i've seen . ok now it tells me this: so i copied rmr2 too like i did with functionnal , but nothing happend , there is the full error :
