Problem to identy gene symbol from ref id

Hi I faced a massive problem .I want to analyze a GEO dataset to see the differentialy expressed genes through limma packages.But when i download the dataset I saw that there was ref id instead of gene symbol .So my question is how i can convert the ref id into gene symbol in R in that case??

Both biomaRt and the org.db packages can convert from ref ids to gene symbols also.
