+improve cancer care.  RTCGA package offers download and integration of the
+variety and volume of TCGA data using patient barcode key, what enables easier
+data possession.  This may have an benefcial infuence on impact on development
+of science and improvement of patients treatment.  Furthermore, RTCGA package
