Run R script on Amazon EC2

I am working with large datasets in R and some of the computations are too heavy for my machine in terms of RAM (cannot allocate vector of size n Mb). 

sessionInfo()

R version 3.1.2 (2014-10-31) Platform: x86_64-w64-mingw32/x64 (64-bit)

locale: [1] LC_COLLATE=English_United Kingdom.1252 LC_CTYPE=English_United Kingdom.1252
[3] LC_MONETARY=English_United Kingdom.1252 LC_NUMERIC=C
[5] LC_TIME=English_United Kingdom.1252

attached base packages: [1] stats graphics grDevices utils datasets methods base

I have access to an Amazon EC2 external server with up to 30 GB RAM which should be enough. My question is how I can run an R script on this external server using my local machine? Is there a function for this?

you would have to put script on the external machine and then run it:

ssh [email protected] 'my_script.r'

Much nicer way of doing that would be to use RStudio server.
