Data Preparation 





This semester we will be working on R. R is an integrated suite of software facilities for data manipulation calculation and graphical display. R was inherently made for statistical computing and graphics of data and very similar to the S language. Which means code written in S can run syntax free in R. R provides a wide range of statistical linear and nonlinear modeling. Often used as the choice in statically methodology. It was very simple and easy components such as mathematical symbols and formulae. R is a great design choice for a user to retain control. R runs on wide range of operating systems like Linux platforms FreeBSD Windows MacOS. This week I worked on getting my R IDE configurated and ready to take in data. The R environment is very effective at data handling and storage facility. Operators for calculations on an array or matrices is possible in R. R has coherent integrated collection of intermediate tools for data analysis. R also can display data analysis in a well developed way. The R language also contains many of the fundamental cores of software languages like "Loops" ,"Conditionals" and recursive functions. R has many capabilities an important one is connection with C programming language. The ability to link code with C and C++ also make it very useful to manipulate code such as use R objects using C. R can easily be extended and used properly.


 I installed all the R packages needed to execute and run our code in the R studio console window. Cleaning data is very time consuming “dplyr” and “tidyr”  packages are quick and easy to learn.  We used a data set from the Starwars universe which had 87 characters and 13 variables. We used the select function to limit our variables name, height, gender we used (and) “&”Logical operators and the (or) “ | ”Logical operator to combine a dataset. Also created functions that can calculate the height and mass of the characters in The Starwars Universe data set. Then we used if else statements to return Boolean strings to determine if a character was tall or short.

  Abinezer Abebe STEM  Week 2                                       Computer Based Programming Languages Research   There are varies types of computer programming languages. Python is a interpreted programming language. Interpreted programming languages it incorporates modules exceptions and dynamic typing. Its a very high level programming language. Pythons writability and readability is why its ranked so high on most popular languages next to java and C. Python code is easily portable and has thousands of free open code programs. Why would a user choose python over C? C programming language works well with internal software and while python is a general all purpose language that can complete most tasks. Taking a look at python and C. C was first used in 1972 and designed by Dennis Ritchie and Bell labs. The main purpose of C at the time was for US Army development. Time went on and C was used in small electronics and became more practical. C was also used on the Unix operating syste

Abinezer Abebe STEM  Week 3                                       Computer Based Programming Languages Research   Most video games are made from custom code based on the C programming language. Game programming requires substantial skill in software engineering. There are 7 phases a program goes through before the game is published. The first and important is prototyping. The programmer might write down some ideas and figure out the game plans and how the game would work. Is the game going to be multiplayer is the game going to be online ? The programmer would come up a concept. Next step would be the game design. Here the programmer might Collab with others to deign the characters the game scene. Programmers often follow closely the game design that they have set. As they code every line of the program they capabilities are discovered and exploited. During production the programmer may create a great deal of source code to create his game. They also might use free open source code so

   Abinezer Abebe STEM  Week 8                                                                  Computer Based Research One of the biggest growing fields in Computer Science is Artificial Intelligence and Machine Learning. Artificial Intelligence is different from basic programs because you aren't the one solving the problem but the computer itself. Artificial Intelligence uses Machine learning software's to fed to the computer this way the computer is "learning". For example a computer can detect images and identify and name the object. For this to work programmers would fed the computer countless pictures of what a dog is considered. Based of those pics you can test the computers knowledge and ask it if a picture is a dog or not. Also there are 5th Generation computer languages these vary from 3rd and 4th gen. In 3rd Generation languages the user is working with a programming language that isn't low level 0 and 1 code it has easier usability and has more key wo
