R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

summary(cars)
##      speed           dist       
##  Min.   : 4.0   Min.   :  2.00  
##  1st Qu.:12.0   1st Qu.: 26.00  
##  Median :15.0   Median : 36.00  
##  Mean   :15.4   Mean   : 42.98  
##  3rd Qu.:19.0   3rd Qu.: 56.00  
##  Max.   :25.0   Max.   :120.00

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot. 8.1 Which numbered individual had the highest betweenness centrality? 83

8.2 Which numbered individual had the highest betweenness centrality? 83

8.3 What cluster (color) did the individual with the highest betweenness belong to? Cluster 4 the color associated with Cluster 4 red

8.4 What cluster (color) did the individual with the highest closeness belong to? Cluster 4 red (since node 83 also had the highest closeness score)

8.5 Given this drug network, what can be said about the individual with the highest closeness score?

The individual with the highest closeness score (83) is centrally positioned within the network and can quickly reach other members. Because this individual also has the highest betweenness centrality, they likely serve as both a key connector within their cluster and an important bridge between different clusters, making them highly influential in the drug network structure.
