Use the dаtаset belоw which prоvides infоrmаtion on all the flights with the planes which were manufactured between 1995 and 2006. This dataset is created by joining the flights and planes datasetflightsplane %rename(manu_year = year) %>%filter(manu_year > 1995 & manu_year < 2006) %>%inner_join(flights, by ="tailnum")Using ggplot create a histogram using the above dataset, and create sub-plots with the distribution showing arrival delay(arr_delay) variable. The subplot should be based on the manufacturing year(manu_year). The binwidth should be 50, the border color should be blue, and the plot fill should be red. Total number of rows must be 2.Once you plot this, please indicate the manufacturing year which had the maximum count value for any bin.The partial code is as follows. ibrary(tidyverse)ggplot(data = flightsplane, mapping = aes(x = ????)) +geom_histogram(binwidth = 50, color = "blue", fill = "red") +facet_wrap(~????, nrow = 2)
