Develop an R program to create a box plot to compare the Sepal Length across different species in the iris dataset. Ensure the plot highlights outliers with a specific color and shape, includes notches to compare medians, and applies appropriate labeling and styling.

Create a R program to calculate and visualize co relation matrix for a given data set with color coded cells the strength and direction of co relations , using ggplot2 geom_tile function

Develop a script in R to create a violin plot displaying the distribution of a continuous variable, with separate violind for each groups, using ggplot2.

Write an R program to create multiple dot plots for grouped data, comparing the distributions of variables across different categories, using ggplot2’s position_dodge function

9-Create multiple histograms using ggplot2::facet_wrap() to visualize how a variable (e.g., Sepal.Length) is distributed across different groups (e.g., Species) in a built-in R dataset.

This study aims to analyze the extent to which marketing expenses and cost of goods sold (COGS) affect company profits in major markets across the United States. Using a robust regression approach and data from a coffee chain dataset, the research investigates the strength and significance of these financial variables in influencing profitability. The findings are expected to provide strategic insights for businesses seeking to optimize costs and maximize returns in competitive market environments.
