R Programming Assignment Help

R is a freely available programming language developed for statistical computing and graphical representation. It is widely used by statisticiansand data scientists as a major tool for conducting data mining and statistical data analysis.R is an implementation of S programming language linked with lexical scoping semantics inspired by a programming language called ‘Scheme’.

Initially, R programming was developed by Robert Gentlemen and Ross Ihaka at Auckland University. However, it is presently being nurtured by R Development Core Team. It is a GNU project and can be readily acquired from GNU General Public License.

Writing R programming assignment requires a thorough understanding of the complex statistical tools and techniques. Students often commit a structural error that degrades the quality of their assignments. With R programming assignment help,students not only develop their understanding of semantics and statistics but also able to achieve the grade they deserve.

Data Analysis Methods using R Software

R is a powerful programming language for statistical analysis and graphics. Students who are looking for quality solutions to their assignment must understand the ways to apply statistical techniques and graphical methods of data analysis using R programming software. Some of the broadly used methods under our R programming online assignment helpare:

Regression Modeling (Linear and Nonlinear) - Regression analysis is a statistical process that determines the relationships among variables. It comprises various techniques of modeling and analyzing several variables to investigate the relationship between a dependent variable (response) and independent variable (predictors). It measures the average value of the dependent variable when the independent variables are fixed. Primarily, linear regression and non-linear regression techniques are used for carrying out regression analysis methods.

Linear Regression- This method is commonly used to describe data and to establish the relationship between one dependent variable (y) and one or more independent variables (Xi).
y = β0 + ∑ βiXi + εi where, β represents linear parameter, and ε represents the error terms

There are several linear regression analyses model available.

  • Simple linear regression (one predictor)
  • Multiple linear regression (multiple predictors)
  • Multivariate linear regression (multiple response variables)

Nonlinear Regression- It specifies the dependent variable as a function with a set of nonlinear parameters and one or more variables that fit to the data.
y = f(X,β) + ε
Nonlinear regression can be used to fit nonlinear functions or complex models to the data, generate predictions and analyze parameter confidence intervals.

Time Series Analysis- It is a method that deals with time-based data. It is the collection of meaningful statistics and well-defined data through repeated measurements over time. Time series models are extensively used by business houses to analyze website traffic, competition positioning, sales and more. There are following steps essential to explore time series data in R statistical software.

  • The first thing to analyze time series data is to read it into R using the scan() function.
  • After reading the data, it is important to score the data in a time series object in R.
  • The next step is plotting the data with a plot.ts() function in R.
  • The further step is to measure the accuracy of the model. Select methods and tools among exponential smoothening using state space model and ARIMA modeling for evaluating univariate time series forecasts.
  • Once the model has observed the accuracy, next step involves identifying underlying patterns like seasonality, trend, stationary and non-stationary.
  • After identifying patterns, apply transformations to the data, if required, based on trends reported in the data.

Classical and Statistical Hypothesis Tests- Hypothesis testing is a useful statistical tool used by statisticians to evaluate data and draw a conclusion. It helps in the decision-making process. Broadly, there are two types of Statistical hypothesis: Null hypothesis (denoted byH0) where sample tests are estimated purely from chance, and Alternative hypothesis (denoted by Ha) where sample observations are influenced by non-random cause.

The process of hypothesis testing consists of the following steps:

  • State the null and alternative hypothesis.
  • Develop an analysis plan by determining the way to use sample data.
  • Collect and analyze the sample data.
  • Interpret results by applying the decision rule defined while formulating analysis plan.

Data Mining- It uses algorithms and techniques to analyze patterns and establish relationships from a large dataset. Data mining software is used in areas like cybernetics, genetics and marketing, text mining, mathematics and webmining. Data mining method comprises certain parameters including pattern discovery, sequence and path evaluation, classification and clustering.

Data warehousing-It is a technology that integrated the data from diverse sources into a database or program. Most of the business data are analyzed using this method. R language works as a mediator for conducting critical analysis with database management. There are two approaches to data warehousing:

  • Top-Down Approach- The analyst spin off the data segments for a confined group of users to analyze.
  • Bottom-Up Approach- Here, analysts first build the type of data they want and then create a data warehouse based on those specifications.

Classification Clustering- Cluster analysis is a method for finding hidden patterns and groupings in a database by applying one or more clustering algorithms. These algorithms form groups based on similar patterns in the data within the cluster. This technique is used for sequence analysis, genetic clustering, sequence and pattern mining, image segmentation, computer graphics and object recognition. Based on specific characteristics, clustering algorithms are categorized as; Connectivity-based clustering, k-means clustering, Density-based clustering, Distribution-based clustering

Important Areas under R programming Assignment Help

Mapping- In addition to statistics, R is important in the geographical information system for plotting data onto maps. Mapping in R language helps students in making publication ready maps.

Graphics- It is another challenging area where students require practical understanding for effective assignment writing. People pay more attention to pictures that to numbers. Graphs are preferred over others for exploring data.

T-Test- It is one of the demanding areas in statistics that is used to figure out whether the two sets of data are significantly different from each other.

SQL- Structured query language is a programming language that is often used for basic calculation and retrieving data for analyses and visualization in R. Students learn how to create, clean, and manipulate datasets within R using the rational database to perform statistical operations.

R packages

Packages are a compilation of R data, documentation, code and functions in a structured manner that can be easily shared with others. Library is the directory where packages are archived. Every package contains one or more R function. R facilitates various data operations ranging from statistical operations to machine learning, plotting, and graphical representation. A vast library of R packages is available for performing these operations.

The users need to install packages for performing a considerable amount of statistics. Some packages are automatically loaded while installing R. Others need to be installed like ‘graphics’ package that helps to define plots and the ‘stats’ package that provide extensive statistical functionality.
