[R] problems editing R console

[Mark Sharp]

Rosa,

See save() and load() functions for background. However, I suspect you will want to do something as described in the article in this link http://www.fromthebottomoftheheap.net/2012/04/01/saving-and-loading-r-objects/

Is there a way to save the results in a  format that I can use the values? Just apply my corrections and don’t have to do the 2000 simulations for each setting again?
