Thanks for the video. Could you help me here.
Below is the code (creating data frame and printing ), I wrote and ran in w3schools editor

df <- data.frame(
names=c("a", "b", "c"),
details=c("manager", b="analyst", "developer")

print(str(df))
)

As I am using str in print, am getting NULL in last after running the program

I must have to print and use str to inspect data frame.

How to avoid null here ?
