r - Unable to connect to Oracle with ROracle package

Question

I am trying to use ROracle package to connect to the oracle db from Windows desktop, I am getting this error:

library(ROracle)
Error: package or namespace load failed for ‘ROracle’ in inDL(x, as.logical(local), as.logical(now), ...):
 unable to load shared object 'C:/Users/e598140/Documents/R/R-3.4.1/library/ROracle/libs/x64/ROracle.dll':
  LoadLibrary failure:  The specified module could not be found.

Any ideas how to fix this?
