+Rdata parser
+==========================
+**What it does**        
+
+
+The Rdata parser tool allows to extract informations from a binary R file in .RData format. 
+
+
+It produces a summary file and extract the selected dimensions. 
+	   
+More informations concerning R Data format and save / load functions can be found here:  http://www.sthda.com/english/wiki/saving-data-into-r-data-format-rds-and-rdata&gt.

+
+
+|
+
+**How to use it**
+
+First use the Rdata reader tool to get the list of dimensions available in the binary file.
+
+Use the reader tool output to select the dimension(s) you want to extract.
