## Millennium Prize Problems: Solve 1 Problem get US 1 million dollar

Are you want to  won 1 million dollar  prize from the solve mathematics problem, Here is the some Millennium Prize Problems are seven problems in mathematics. These are the problems:

1. Birch and Swinnerton-Dyer conjecture,  (Unsolved)
2. Hodge conjecture,  (Unsolved)
3. Navier–Stokes existence and smoothness,  (Unsolved)
4. P versus NP problem,  (Unsolved)
6. Riemann hypothesis, and  (Unsolved)
7. Yang–Mills existence and mass gap.  (Unsolved)

If you solve any of the above problem, you will won US \$1 million prize being awarded by the institute to the discoverers.At present, the only Millennium Prize problem to have been solved is the PoincarĂ© conjecture, which was solved by the Russian mathematician Grigori Perelman in 2003.

## R Programming: 1. Introduction and installation

This this first tutorials about the R programming, we going to post all the tutorials about the R programming too.

R programming is used to gives the statistically data  modeling with textual and  graphically representation as a output with nice format. R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, …) and graphical techniques, and is highly extensible.

Here is the first step of start of R programming to to understand the basic syntax in R. You can practice more and more from the http://tryr.codeschool.com/ .

Installation(Window):

Click on the official R programming site (http://www.r-project.org). Search for the Download section

Click “download R” to get the proper mirror. This should take you to a page something like bellow.

Choose the link for Iowa State University or any other mirror you like.

Choose your operating system. In the tutorial case it was selected Microsoft Windows.

Click “install R for the first time”.

Click on “Save file” to save the installer to your computer.

Double click the .exe file for installation.

Click “Run” to start the installation. Follow the steps. Click next, accept agreement, select your installation folder and finish the installation.

Working on R

Select the R application from your start menu. All coding style should be same what you practiced on R code school.

1. Get and set working directory

getwd()
setwd("/path/to/your/working/directory")

1. ## List of commands

Here are some commands that you can use in your R script.

 Command/word Description Example # The characters after are considered comment #this is a comment cat Print a message to the console (like System.out.println in Java) cat("Hello World!\n") source Execute a R script file previously created source("myScript.r") <- Assign a value to a variable one <- 1 Hello <- "Hello" install.packages Download and install a package install.packages("rpart") library Load a installed library to your R script load(rpart)

OBS: R is case sensitive, so Variable is different from variable.

Thank you !!!
