Indexing or accessing the Data Frame in R
By indexing the Data Frame in R we will get the particular column data. Indexing can be done by specifying column names in square brackets. The syntax for indexing the data frame is-
dataframeName[“columnName”]
R
# create a data frame stats <- data.frame(player=c('A', 'B', 'C', 'D'), runs=c(100, 200, 408, NA), wickets=c(17, 20, NA, 5))print("stats Dataframe")stats# fetch data in certain columnstats["runs"] |
Output:
player runs wickets
1 A 100 17
2 B 200 20
3 C 408 NA
4 D NA 5
stats["runs"]
runs
1 100
2 200
3 408
4 NA
In this example we create a Data Frame “stats” that contains runs scored and wickets taken by a player and perform indexing on the data frame to extract runs scored by players.
Indexing and Slicing Data Frames in R
In this article let’s discuss indexing and slicing the Data Frames or how to access elements of a data frame in R Programming Language.
