EasyR15 min10 XP

Problem

Given a data frame df, return only rows that have no missing values.

Before modeling or plotting, you often need to decide how missing rows are handled.

Example 1

Inputrows A=10, B=NA, C=30

Outputrows A and C

The row containing NA is removed.

CodeR

df <- data.frame(
  name = c("A", "B", "C"),
  score = c(10, NA, 30)
)

# write your code here

df <- data.frame(
  name = c("A", "B", "C"),
  score = c(10, NA, 30)
)

# write your code here
