Extract core points from DBSCAN in R

Given data below, I have applied DBSCAN on those points

set.seed(294056)
df = data.frame(x = runif(1000), y = runif(1000), z = runif(1000))
library(dbscan)
db = dbscan(df, eps = 0.3, minPts =100) # formed 1 cluster
print(db)

DBSCAN clustering for 1000 objects.
Parameters: eps = 0.3, minPts = 100
The clustering contains 1 cluster(s) and 60 noise points.

  0   1 
 60 940 

Available fields: cluster, eps, minPts

I wanted to extract core points from that cluster. Is there a way to extract those points?

In your dbscan set borderPoints = F.

This way, you only retrieve core points by discarding border points.
