The “slice” Function in R

• Package: dplyr

• Purpose: To subset data by selecting specific rows based on their positions.

• General Class: Data Manipulation

• Required Argument(s):

• data: The data frame or tibble to process.

• ...: Row indices or conditions for selecting rows.

• Notable Optional Arguments:

• None.

• Example (with Explanation):

• # Load necessary packages
  library(dplyr)
  
  # Create a sample data frame
  data <- data.frame(
  category = c("A", "B", "A", "B", "A"),
  value = c(10, 15, 8, 12, 10)
  )
  
  # Select specific rows using the slice function
  selected_rows <- slice(data, 2:4)
  
  # Display the selected rows
  print(selected_rows)

• In this example, the slice function from the dplyr package is used to select specific rows from the sample data frame. Rows 2 to 4 are chosen using the 2:4 argument. The result is a new data frame containing only the selected rows. This function is useful for extracting specific observations based on their positions in the dataset.
