Introduction
R is a programming language for statistical computing and graphics supported by the R Core Team and the R Foundation for Statistical Computing. Created by statisticians Ross Ihaka and Robert Gentleman, R is used among data miners, bioinformaticians and statisticians for data analysis and developing statistical software.
Some of the advantages of R are:
r download ios
It's open-source. No fees or licenses are needed, so it's a low-risk venture if you're developing a new program.
It's platform-independent. R runs on all operating systems, so developers only need to create one program that can work on competing systems. This independence is yet another reason why R is cost-effective!
It has a rich package ecosystem. There are thousands of packages available on CRAN (the Comprehensive R Archive Network) that provide functions and tools for various domains and tasks, such as data wrangling, visualization, machine learning, web scraping, etc.
It has excellent graphical capabilities. R can produce high-quality plots and charts that can be customized and exported in various formats.
It has a large and active community. There are many online resources, forums, blogs, books, courses, and events that can help you learn and improve your skills in R.
Installation
To use R on your iOS device, you will need to install two software: R itself and RStudio. RStudio is an integrated development environment (IDE) that provides a user-friendly interface and many features to make coding in R easier and more efficient.
Here are the steps to install R and RStudio on iOS:
Go to the and click on "Download R for (Mac) OS X".
Click on the link for the .pkg file of the latest R version and save it.
Double click the downloaded file and follow installation instructions.
Go to and click on the download button for RStudio Desktop.
Click on the link for the iOS version of RStudio and save the .dmg file.
Double click the downloaded file and drag the RStudio icon to your Applications folder.
Examples
Now that you have installed R and RStudio on your iOS device, you can start coding in R. Here are some examples of how to use R for different purposes:
Data manipulation
R has many packages that can help you manipulate data in various ways, such as filtering, transforming, summarizing, joining, reshaping, etc. One of the most popular packages for data manipulation is dplyr, which provides a consistent set of verbs that operate on data frames or tibbles (a modern reimagining of data frames).
Here is an example of how to use dplyr to filter rows of a data frame based on some conditions:
```r # Load dplyr package library(dplyr) # Create a data frame of cars cars % filter(type == "Sedan", mpg > 25) `` The output of the code above is: model type price mpg --- --- --- --- Toyota Sedan 25000 30 BMW Sedan 40000 25 Tesla Sedan 45000 100 As you can see, dplyr makes it easy to filter data with logical expressions. You can also use other verbs, such as select, mutate, arrange, group_by, and summarize, to perform other data manipulation tasks. For more information on dplyr, you can check out the . Plotting
R has many packages that can help you create beautiful and informative plots and charts from your data. One of the most popular packages for plotting is ggplot2, which implements the grammar of graphics, a system for describing and building graphs.
Here is an example of how to use ggplot2 to create a scatter plot of the cars data frame:

```r # Load ggplot2 package library(ggplot2) # Create a scatter plot of price vs mpg ggplot(cars, aes(x = price, y = mpg)) + geom_point() + labs(title = "Price vs MPG of Cars", x = "Price ($)", y = "Miles per Gallon") ``` The output of the code above is:
As you can see, ggplot2 makes it easy to create plots with layers of aesthetics and geoms. You can also use other geoms, such as bars, lines, histograms, boxplots, etc., to create different types of plots. For more information on ggplot2, you can check out the . Machine learning
R has many packages that can help you apply machine learning techniques to your data, such as classification, regression, clustering, dimensionality reduction, etc. One of the most popular packages for machine learning is caret, which provides a consistent interface and tools for building and evaluating predictive models.
Here is an example of how to use caret to train and test a linear regression model on the cars data frame:
```r # Load caret package library(caret) # Split the data into training and testing sets set.seed(123) # for reproducibility train_index <- createDataPartition(cars$price, p = 0.8, list = FALSE) train_set <- cars[train_index, ] test_set <- cars[-train_index, ] # Train a linear regression model on the training set model <- train(price mpg, data = train_set, method = "lm") # Test the model on the testing set predictions <- predict(model, newdata = test_set) performance <- postResample(predictions, test_set$price) performance ``` The output of the code above is: RMSE Rsquared MAE --- --- --- 3989.6 0.8869 2985.8 As you can see, caret makes it easy to train and test models with various methods and parameters. You can also use other methods, such as knn, svm, rpart, etc., to create different types of models. For more information on caret, you can check out the . Tutorials
If you want to learn more about R and practice your skills interactively, there are many online tutorials that can help you. Here are some of the best ones:
: DataCamp offers courses and projects on various topics and levels of R programming, such as introduction to R, data visualization with ggplot2, machine learning with caret, etc.
