I want create gene interaction network like this. They have done with Ingenuity Pathways. Alternative to this was suggested ipathwayguide. Both are paid software. Are there any free tool to generate this image.
Assuming that you identify genes of interest separately (IPA will do all that internally) you should be able to use this tutorial: Network plot from expression data in R using igraph
There is also Cytoscape (now unlicenced I believe), in addition to SRINGdb mentioned by cpad.
Try stringdb package.
