“Adults Only” hotels are intended for people who want to relax and enjoy a holiday as a couple or with friends in an exclusive environment. Riu Palace hotels add extra luxury, excellence and sophistication to our guests' stays. These hotels are always located right on the beach and offer the best services to guarantee an unsurpassable stay.
RStudio v1.1 Released
In this course you will learn how to program in R and how to use R for effective data analysis. You will learn how to install and configure software necessary for a statistical programming environment and describe generic programming language concepts as they are implemented in a high-level statistical language. The course covers practical issues in statistical computing which includes programming in R, reading data into R, accessing R packages, writing R functions, debugging, profiling R code, and organizing and commenting R code. Topics in statistical data analysis will provide working examples. Help operator in R provide access to the documentation pages for R functions, data sets, and other objects, both for packages in the standard R distribution and for contributed packages.

We think this is a must-have upgrade because it delivers credible, agile, and durable tooling for serious data science. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page. CRAN Task Views are documents that summarize R resources on CRAN in particular areas of application, helping your to navigate the maze of thousands of CRAN packages.
RStudio 1.2 Preview: The Little Things
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free. The mission of The Johns Hopkins University is to educate its students and cultivate their capacity for life-long learning, to foster independent and original research, and to bring the benefits of discovery to the world. This week, we take the gloves off, and the lectures cover key topics like control structures and functions.
The R Foundation for Statistical Computing was founded in April 2003 to provide financial support. The R Consortium is a Linux Foundation project to develop R infrastructure. As an interpreted language, R has a native command line interface. Moreover, multiple third-party graphical user interfaces are available, such as RStudio—an integrated development environment—and Jupyter—a notebook interface. The core R language is augmented by a large number of extension packages, containing reusable code, documentation, and sample data.
Are you headed to Strata? It's next week!
With growing support for a wide range of development environments, we believe this new release is the best single platform to support open source, code-first data science, whether your team is using R or Python. This week covers the basics to get you started up with R. The Background Materials lesson contains information about course mechanics and some videos on installing R. The Week 1 videos cover the history of R and S, go over the basic data types in R, and describe the functions for reading and writing data. I recommend that you watch the videos in the listed order, but watching the videos out of order isn't going to ruin the story.
Before asking others for help, it’s generally a good idea for you to try to help yourself. R includes extensive facilities for accessing documentation and searching for help. There are also specialized search engines for accessing information about R on the internet, and general internet search engines can also prove useful (see below).

RStudio v0.98 Preview (Debugging Tools and More)
We also cover the profiler in R which lets you collect detailed information on how your R functions are running and to identify bottlenecks that can be addressed. The profiler is a key tool in helping you optimize your programs. Finally, we cover the str function, which I personally believe is the most useful function in R. If you find that you can’t answer a question or solve a problem yourself, you can ask others for help, either locally (if you know someone who is knowledgeable about R) or on the internet. In order to ask a question effectively, it helps to phrase the question clearly, and, if you’re trying to solve a problem, to include a small, self-contained, reproducible example of the problem that others can execute.

This gives you handy and easy way to use functions in series without creating variables and storing intermediate values. In this case we explicitly use dot rather than eliding the dot argument and end each component of the pipeline with an assignment to the variable whose name is dot (.) .

We have now entered the third week of R Programming, which also marks the halfway point. The lectures this week cover loop functions and the debugging tools in R. These aspects of R make R useful for both interactive work and writing longer code, and so they are commonly used in practice. We have created three tracks to help learners navigate the R ecosystem. These tracks are not meant to be exhaustive, but instead are designed to help you become productive in the minimum amount of time, based on your experience level. The R Core Team was founded in 1997 to maintain the R source code.
If you have questions about R like how to download and install the software, or what the license terms are, please read our answers to frequently asked questions before you send an email. R is a free software environment for statistical computing and graphics. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS. To download R, please choose your preferred CRAN mirror.
One of R's strengths is the ease of creating new functions.[26] Objects in the function body remain local to the function, and any data type may be returned.

It includes articles on packages, programming tips, CRAN news, and foundation news. The Bioconductor project provides packages for genomic data analysis, complementary DNA, microarray, and high-throughput sequencing methods. The piped version is more natural to read left-to-right, with less parentheses, as steps in a data transform/modeling task. It also lets you easily insert steps into your process without fiddling with nested functions. This week covers how to simulate data in R, which serves as the basis for doing simulation studies.
Before posing a question on one of these lists, please read the R mailing list instructions and the posting guide. R, like S, is designed around a true computer language, and it allows users to add additional functionality by defining new functions. Much of the system is itself written in the R dialect of S, which makes it easy for users to follow the algorithmic choices made. For computationally-intensive tasks, C, C++ and Fortran code can be linked and called at run time. Advanced users can write C code to manipulate R objects directly.
