R Programming Language is a programming language used for statistical computing and advanced data analysis. It is the language of choice for many data analysts and statisticians, allowing them to work with large amounts of data quickly and efficiently. The language provides a platform for manipulating, displaying and presenting statistical datasets related to various disciplines such as mathematics, computer science and engineering.
An R Programmer can create many types of statistical calculations such as linear and nonlinear models, hypothesis tests and experiments, clustering, classification and regression trees. Additionally, they can make custom metrics more accessible through the writing of functions, plots and charts to make them easier to read and interpret. Plus they can take data from various sources like text files, database systems or HTML webpages and transform it into tidy sets ready for further action. Of course all of this can be done with careful formatting in order to achieve the best possible results unlocking valuable insights from ever-increasing amounts of data around us.
Here's some projects that our expert R Programmers made real:
- Data cleansing techniques to make numerical datasets easier to read and interpret
- Complex algorithms that aim to solve a wide range of problems from predicting stock prices to optimizing machine learning models
- Advanced visualizations that reveal important trends across different industries
- Automated tools that make digital transformation faster for businesses
- Statistically sound research methods for solving complex problems

So I would want the code for R with the output. Otherwise I can't proceed. VBA might be sufficient but I want to work with R. I am going to give you a little more information. From the example file sent. I want to match the keywords from with the Keywords in the column 44 Keywords. So for example taking the following example (row 30) [Column 4 Title] A highly selective and sensitive disposable carbon composite PVC-based membrane for determination of lead ion in environmental samples by [Column 2 Author] A.; Mirahmadi Abbaspour, E.; Khalafi-Nejad, A.; Babamohammadi, S We can see in [Column 44 Keywords Copy1] (which is the a copy of the column 29 Keywords this was for my information not yours) the following Key words are listed: *Carbon; Environmental Pollutants/*analysis; *Ion-Selecti...
I am looking for a freelancer who can apply statistical significance measures to evaluate the performance of machine learning models. i applied 10 machine learning models, and I conducted an experiment with 10 stacked ensemble models for classification, evaluating them using 7 performance metrics (accuracy, precision, recall, f1-score, exact match ratio, hamming loss, and the zero-one-loss). The proposed model showed the best performance. Specifically, I want to answer this question “In the results, in comparing the different models, you are to adopt statistical significance measures to ensure performance significance.”
