Importing a .Rdata file in .NET

Question

I'm quite novice with R and I don't quite understand a few simple things. I need to load an .Rdata file using C#.NET. I've installed the R.NET library and I've initialize the engine without any issues. What I'm struggling is how to import a file , load its content into a dataframe and from that point manipulate the dataframe. I've also checked the internet but I go stuck. The following image was taken while following steps I found online. Even the count is incorrect between the Rdata file and the dataframe Any help would be highly appreciated. I will also attach an image of the .Rdata file from the R GUI
