title: Read .rdata without R
body: <p>I have received an .rdata file with what I think should be a list of co-ordinates (x,y) and their corresponding gray value; however, I do not know exactly the data type/format within the .rdata file. Is there a way for me to read these data without R? I do not have access to R. I have Excel and Matlab on a Mac. Please help. Unfortunately, I am not allowed to pass on the data (my Googling tells me someone familiar with R can export the data into a text of csv file easily).</p>
  
  <p>Thank you in advance.</p>
