sort the rows in a spreadsheet so that if any set of four rows contains a duplicate value, then the programme resets in r

# Read the spreadsheet into a data frame
data <- read.csv("your_spreadsheet.csv")

# Define a function to check for duplicate values in a set of four rows
check_duplicates <- function(start_row) {
  for (i in 0:3) {
    row <- start_row + i
    if (row > nrow(data)) {
      return(FALSE)
    }
    if (anyDuplicated(data[row, ])) {
      return(TRUE)
    }
  }
  return(FALSE)
}

# Sort the data frame by the desired column(s)
sorted_data <- data[order(data$column_name), ]

# Loop through the rows of the sorted data frame, checking for duplicates
for (i in 1:nrow(sorted_data)) {
  if (check_duplicates(i)) {
    # Reset the program
    # Your code here...
  }
  # Your other code here...
}
