A Sample R-project: Mapping Crime Data Using the Leaflet R-library

Case Study: You have been presented with crime data and a researcher wants to extract some insights from the data. To effectively help the researcher, you are supposed to use the Leaflet R-programming library to map the data. After mapping the data, you will write a small report about the findings.

The Crime Data Mapping: Distribution Across Different Continents

Findings of the Mapped Crime Data

To extract insights from the crime data, the Leaflet library of the R-software was used for mapping. Based on the results, North America has the highest crime rates. This is followed by Europe, South America, Africa, and Australia.

In North America, Majority of the crimes seem to happen inland. Not the case with Africa, Australia, Europe, and Asia, and Australia as many of the crimes in these continents seem to happen on the coastline.

In South America, Australia, and Africa, the crime occurrences are sparse and don’t concentrate in one location. However, in North America, the crimes seem to concentrate on specific regions with a few instances in other regions.

The Process of Hiring R Freelancers

Amidst the Increase of Big Data; R-Programming Experts Meet the Complex Analysis Needs

The increase in big data has been overwhelming recently. At the same time, there is increased demand for using the data to make business, research, and economic decisions. To respond to the upsurge of the increasing data, R- a programming software has also been evolving. R-freelancers have leveraged this opportunity to expand their services online. The R-studio software has been ranked among the top 20 data analysis software in the market.

Regardless, although r-freelancers have expanded their presence online, linking with an experienced R-studio wizard is not an easy task. Therefore, in this article, we evaluate the process of connecting with experienced r-freelancers online.

What Qualities Differentiate Excellent R-freelancers from Unexperienced Ones?

R freelancers also known as r studio experts should possess unique skills that can benefit clients across all disciplines. Successful r developers have a strong foundation in disciplines like mathematics, data analysis concepts, and also some other complimentary soft skills that make the working process flawless.

  • Statistics: If you want to hire r developer or r freelancer, one of the most important skills is statistics. R freelance career revolves around navigation of complex data sets using advanced statistical concepts. Therefore, a freelancer studio developer should have vast skills in statistical concepts like hypothesis testing, linear regression, probability theory, and causality analysis.
  • Data Visualization and Manipulation: Before you think of hiring r programmers, ask yourself, do I need a detailed technical report that I cannot understand or heuristic visualizations that are easy to understand? Most of the time, you will realize you need a simple report and that is where the skills of data visualization and manipulation come in. When hiring any r freelancer or online rstudio developers, ensure that they have vast skills in data visualization and manipulation.
  • Database Management: Excellent skills in database management are important for r freelancers. When you hire r programmers, they should have vast skills in SQL, working with real databases like MySQL, PostgreSQL, and Microsoft SQL Server among others.
  • Machine Learning and Predictive Analysis: Familiarity with machine learning techniques and predictive analysis is becoming an important skill for r studio experts whether working as freelancers or in-house. Any r freelancer should have good skills in ML models like classification, regressions, clustering, NLP, data mining, and ML algorithm development, among other skills.
  • Version Control: R freelancers should be proficient in version control. Though they may not be directly involved in software engineering, an understanding of control systems like Git would be an added advantage. Before you hire r developer, you can ask them for the Git profile you see in their portfolio.
  • Problem Solving Skills: R freelancing revolves around solving advanced data and system problems. As such, when hiring a freelance r programmer make sure that they have the ability to solve technical problems with ease.
  • Communication and Collaboration: Data analysis is a collaborative type of work. You need data engineers, software Engineers, and possibly r programmers to make the work successful. Therefore, excellent communication and collaboration become essential when hiring candidates online.

How Can You Figure Out the Ideal Freelance Rstudio Developers for You?

Determining the needed skills for your r project is a lengthy process. However, you should first define your problem and set the objectives you need to achieve once you hire a r developer. You also need to ensure that the r engineer you hire is able to handle advanced and complex problems relating to R programming. To make effective decisions you can first consult freelance rstudio developers who will help you in vetting your ideal candidate.

Which One Python or R Developers?

Despite the fact that Python programming software is more popular than R-statistics, each of them is ideal in unique settings. These software packages are not there to compete but to complement each other toward the completion of projects.

In many scenarios, freelancer r programmers also have skills in Python for data analysis or even other analysis software like Tableau, Microsoft Power BI, Stata, SPSS, and others. Below is a table of how you can make a judgement of whether you need to hire r studio expert or a Python developer.

Comparing R-developers with Python Data analysts

To summarize the table, you can make the following deductions for R developers and Python developers

  • R developers: This set of experts focuses on statistical analysis, data visualization, manipulation and data wrangling, and reporting. However, they don’t focus on the development of data storage facilities or advanced data mining projects.
  • Python developers: Python developers focus more on developing storage facilities for data, writing ML algorithms, and extracting and mining data from databases.

R Programming Compared to R Data Analysis

Though these two use the same software, that is the R-statistics software package, they have different purposes. However, note that r freelancers can serve as r programmers and r data analysts. Therefore, it depends on your research goals or business case.

For R programming, this involves the development of r custom scripts, functions, and applications. They serve businesses in doing repetitive tasks. R data analysis involves the analysis and reporting of large data sets.

When hiring r developers with the objective of getting r programming services, you can test their ability to code using the r software. However, for r freelancers focusing on data analysis, you can test their abilities by how they handle large data sets.

How to Evaluate A junior and Senior Freelance Rstudio Developer?
