Today, I will talk to you about the solution of protein interaction network error reporting in R language visualization STRING analysis, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

Protein interaction Network (PPI) for R language Visualization STRING Analysis

Some friends left messages saying that they were repeating.

Net nodes edges nodes

Node

1 A

2 B

3 C

4 D

> edges

Node1 node2

1 A B

2 A C

3 A D

4 B C

5 B D

6 C D

And then there's visualization.

Library (ggraph)

Library (igraph)

Net which (edges1 $node2 in% nodes$node)

[1] 1 2 3 4 5 6

> which (! Edges1 $node2% in% nodes$node)

[1] 7

This means that row 7 of the node2 column is not in nodes.

Then we can delete this line.

Another way is to add E to the node df1
