r count distinct dplyr

To count distinct values in a column using the dplyr package in R, you can follow these steps:

1. Load the dplyr package:

library(dplyr)

1. Create a data frame or use an existing data frame:

data <- data.frame(column_name = c("A", "B", "A", "C", "B", "D"))

1. Use the distinct() function from dplyr to get unique values in the specified column:

distinct_data <- distinct(data, column_name)

1. Use the nrow() function to count the number of rows in the new data frame:

count <- nrow(distinct_data)

1. Print the count to see the result:

print(count)

These steps will help you count the distinct values in a specific column using the dplyr package in R.
