R 编程语言 Jobs

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

By hiring an R programmer on Freelancer.com, you get access to a versatile set of solutions tailored specifically to your needs that help you make sense of your data in a more meaningful way. This way you can draw important conclusions easily while freeing up resources that you can use in other endeavors. So if your business requires someone experienced in R Programming Language then why not give it a try and post your project on Freelancer.com?

    Good afternoon, I am a University Professor of Psychology and I have a project funded by FCT in the field of criminology. I would like to develop software (which I have partially programmed in Excel already). This software aims to: 1) work with dichotomous variables that are temporally distinct (for example, at 3 or 4 fixed and different times); 2) map all the sequences that appear in the sample more often than expected by chance, i.e., more than the upper CI of the multiplication of their individual probabilities (each variable at each time would generate a different sequence), and then assess each sequence's probability of predicting a dichotomous event, calculated via ORs. From the list of variables that appeared first in time, let's say, the first assessment was at age 8, to...
