Hey guys, this is the introduction to R.
To get in to R system, all you have to do from a windows system
- go to R icon, double click it or
you could do something else - like - go to start menu - all programs - R folder, then R!
Now .. umm .. this font look a bit small to you may be -
ok - i'll change the GUI preference - set it to 20 size
- with bold may be, yeah!
That should be it!! Wow! Lots of things!!!
Umm .. to get rid of the things in the screen,
in R, press ctrl+L - yeah - that does the magic!
Now .... we are trying to get introduction for R
- what do we do in R, ..
At first, we do the calculations in statistics -
to do any analysis - first we have to create the vectors.
We start by creating simple vectors.
Ok! How do we create vectors in R?
Say, I put x, notice that its small x, not capital x.
x = concatenate c, small c obviously, bracket starts
let the vector be 1, 2, 3, 4, 5 - thats it!
Now we can see what is in x -
print x - yeah - 1 2 3 4 5!
Lets say, we want to create vector but in another way
say the way is x1
