Gene ontology and Gene Interaction Network in R

Hello,

I have a dataset of gene expression organized as follows:

  Gene      FC12h        QV12H           FC10d             QV10d                   
  Rp1      -0,371        0,797           2,647             0,718
  Sox17     15,200       0,438           2,946             0,445    
  Mrpl15   -1,789        0,218           0,752             0,004    

FC represents the folding change and QV the q-value for two situations: 12 hours and 10 days. I already searched a lot, downloaded packages and could not do an analysis of the differential expression of these genes; the most I could do was make a heatmap and separate the differentially expressed genes for each situation. I need to make a gene ontology with these differentially expressed genes and also a network of gene interaction. Someone from some package, any tips, anything that can help me?
