I have extensive experience in programming and data analysis using R. I have worked as a freelance programmer for several clients, developing programs for a wide range of tasks such as data analysis, statistical analysis, machine learning and natural language processing. Additionally, I have experience working with R packages such as dplyr, ggplot2, tidyr, lubridate, and caret. I have also worked with other programming languages such as Python, Java, and C++. My experience also includes data visualization, data wrangling and cleaning, and web scraping.
