I have extensively used both R and Python for data analysis, visualization, and modeling. Each language has its strengths, and I have leveraged them based on the specific requirements of the projects I worked on. I employed libraries like Matplotlib and Seaborn to create visualizations that clearly communicated complex insights. For example, I developed visual reports to illustrate trends in energy usage over time, which were used in presentations to stakeholders.I utilized R for advanced statistical analysis, particularly in hypothesis testing and regression analysis. R’s statistical packages, such as dplyr and ggplot2, allowed me to conduct thorough analyses and create high-quality visualizations. For example, I performed a time series analysis to identify seasonal patterns in energy consumption, which informed marketing strategies.I used R Markdown to create dynamic reports that integrated code, output, and narrative text. This was particularly useful for sharing insights with non-technical stakeholders, as it allowed me to present findings in a clear and cohesive manner.
