How to use R-packet STRINGdb for protein interaction network analysis

This article is about how to use R-packet STRINGdb for protein interaction network analysis. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Protein-protein interaction network analysis using R-packet STRINGdb

After the difference analysis is completed, a protein interaction network analysis can be done to see which genes only interact with the differential proteins.

There are many ways to achieve this goal. Generally speaking, it is more common to use STRING as a website for analysis. In fact, using R-packet STRINGdb can also be achieved. The code reference is as follows:

# install STRINGdb package # source ("https://bioconductor.org/biocLite.R")# biocLite (" STRINGdb ") # # # # library (STRINGdb) # set the program parameter work_dir
