Hi to everyone I have a big dataset (40.000 columns (variables) and 50 rows) I want to impute a lot of ?variables ?with ?library(mice), the problem is that this process is too slow (because of my dataset, the library is brilliant). I am looking some options like Amazon web services, (?http://aws.amazon.com/es/datapipeline/developer-resources/?) Has anyone used this service or knows other options? Any ideas are welcome. Thanks in advance
Library(mice) too slow for my dataset

Dear Teresa, using such services will only speed up the imputations significantly if you can split up/parallelize your code. And maybe you can use more cores on your local machine by using packages like doSNOW, foreach and/or plyr. There are a lot of examples on the web.
