title: Extracting specific data from an RData file
body: <p>I ask to be excused for my ignorance of R which I have been learning for the past one month. Specifically I have downloaded xxx_adm-_RData files (xxx for the country and - being 0, 1 or 2) for a number of countries of interest. My real interest are just the long/lat coordinates of each country, which I can use to overlay on analyses of climate fields like rainfall, temperature, etc. For the past two weeks I have been going through SO posts on how I can access a country's coordinates in an RData file and use them with other data, without any success. My attempts to get google maps or readGR() or readBin() after a download have not been successful. I wonder whether what am asking for is feasible.</p>
