Example 1: Delete Single Row of Dataframe in R
# Create a data frame
dataframe1 <- data.frame (
Name = c("Juan", "Alcaraz", "Simantha"),
Age = c(22, 15, 19),
Address = c("Nepal", "USA", "Germany")
)
# delete 1st row
print(dataframe1[-1, ])
# extract 1st and 3rd row
print(dataframe1[-c(1,3), ])
Output
Name Age Address
2 Alcaraz 15 USA
3 Simantha 19 Germany
In the above example, we have created a dataframe named dataframe1. And we have deleted a row using the index value and - sign.
Here, dataframe1[-1, ] deletes entire elements of 1st row
Example 2: Split Dataframe by Column Names in R
# Create a data frame
dataframe1 <- data.frame (
Name = c("Juan", "Alcaraz", "Simantha"),
Age = c(22, 15, 19),
Address = c("Nepal", "USA", "Germany")
)
# delete 1st and 3rd row
print(dataframe1[-c(1,3), ])
Output
Name Age Address
2 Alcaraz 15 USA
Here, dataframe1[-c(1,3), ] deletes entire elements of 1st and 3rd row.
