Final answer:
To find the top two most frequent counties in an R dataset, use the package. Tally occurrences with , arrange them in descending order, and select the top two with .
Step-by-step explanation:
To find the top two counties that occur most frequently in a dataset using R Studio, you would typically use the dplyr package, which is part of the tidyverse suite of data manipulation tools. Here's a step-by-step example:
First, ensure that the dplyr package is installed and loaded into your R session using install.packages("dplyr") and library(dplyr).
Next, use the count() function to tally the occurrences of each county in the dataset. For example, if your dataframe is named df and the county column is county, you would use df %>25 count(county).
Then, arrange the resulting tibble in descending order using the arrange() function with desc() on the count column: df_count <- df_count %>25 arrange(desc(n)).
Finally, to get the top two counties, use the head() function with n = 2: top_two <- head(df_count, n = 2).
This will give you the names and the number of occurrences of the two most frequent counties in your dataset.
