Statistics with R (part 1: very basic tutorial)
hey guys this is the introduction to our to get in to our system all you have to do from a window system go to our icon down click it or you could do something else like go to start menu or programs our folder then our now how this forms look a bit small to you maybe ok I'll change the GOI preference set it to 20 size with more maybe yeah let repeat Oh lots of things umm to get rid of the things in the screen in our press ctrl L yeah that does the magic now we are trying to get introduction for our what do you we do in our at first we do the calculation in statistics to do any analysis first we have to create the vectors we start by creating simple vectors okay how do we create vectors in our say I put X notice that is small X naught capital x equals concatenate C small C obviously break it starts with the bit will be 1 2 3 4 5 comma 2 comma 3 comma 4 comma 5 and that's it now we can see what is in X er int print X yeah 1 2 3 4 5 let's say we want to create vector but in another way say the way is like X 1 see 1 2 3 4 5 yeah firstly what is in X 1 yeah one two three four five so there are many ways to create the vectors and this is simply the two ways one way was using the Equality and another way is using the sign like this oops so the other ways could be like this say X 2 is 1 if 5 so it is X 2 1 2 3 4 5 or we could use the sequence X 3 equals sequence that starts from 1 amps at 5 with equal intervals 1 so X 3 is 1 2 3 4 5 yeah now we create a new vectors Y it is 6 to 10 yeah remember our X was 1 2 3 4 5 our Y is 6 to 10 so if I want to create some new vector or set which is like the combination of x and y so this is it we can we can do basic arithmetic using the vectors the basic arithmetic is like this like if X is 1 2 3 4 5 then X plus 1 should be 2 3 4 5 6 let's see what whether it is like this or not I mean this is like this so similarly X star it – that means it's month it's much played by 2 R divided by 2 yeah we could go up without typing it all over again and just edit the part where we want to edit this can save our time yeah yeah going in the app button yeah it gives us the history of our yeah now let's say we want to see the vector arithmetic s– like x and y whether it works or not yeah it works perfectly because the length of X and length of Y are similar that's why it works perfectly to check the length of X yeah 5 go up length of Y there's also that that's why it works and we can do similar aesthetic like this X minus y X into y X divided by Y and so on this is how we work we are using vectors and for the vectors we can use the normal arithmetic or use we can use the vector and scalar arithmetic as we have time previous to like X plus 5 this is vector plus scalar and if we do X minus y where X is back to Y is vector this is vector vector arithmetic yeah once we are done with the equity we could use some complex functions like not plus minus in to divide but more complex like that like whatever log say I want to find the logarithm of X yeah this is like this but what sort of logarithm is it I'm not sure so I want to take whether this is the logarithm for ten males or natural okay to look into the help file type question mark log if we know the command in this case we know the common log yeah clock computes logarithm by default natural logarithm so yeah this is the natural logarithm so this is how we work in our there are several other functions like square SQR t square root of x which is like this and we can find the exponential of X yeah this is like this so we came to know about the r and its basic admitting how to create vectors how to look into the help file so this is the part one of our introduction yeah let's hope that we can make it into introduction
How can I get this IDE? please help me everyone.
it is good
Hi +Ehsan Karim
How are you?
Recently I was surfing on Youtube. I come to know about your Youtube Channel. I have viewed so many of your videos. I become fan of your videos and style of making it and represent your ideas.
I am so curious to know about How did you start this? please tell your story
Who did you inspire to motivate to make this amzing and useful videos.?
Why did you start this channel?
How many hours do you give in a week? do you work full time or work on weekends?
Which kind of opportunities do you start getting after making this videos?
How much money do you get from google adsense?
Is it good idea to make videos for full time?
What do you think if everyone start making their own youtube channel to teach something then what will be the future of education?
How much money did you invested to record and edit this videos?
Do you your own studio?
which tools do you use to record these videos and which software do you use for editing?
What message and tips do you like to inspire others to make educational youtube videos?
I wish someone would upload an S PLUS statistics tutorial !
man! amazing! I like this tutorial! I'm new in R! Thanks for this! I'll see the others!
whoa bud how much ram do you have because i see quite a few things running on the bottom right of your screen
Thanks si much, R seems a little less scary after viewing ur tutorial
thanks!
Very nice. Thanks for the effort! And the captions were good too lol
Nice tutorials… I made some tutorials in R also, check that out in my channel.
haa I remember this language you can install GUI on top of it rkward
Thanks for posting your tutorial! It's superb in order to get a first feeling for the program.
very brief, fast and practical. right on to the problem.
are these vectors? I would call them arrays.
Awesome videos! Thanks a ton!
just typing x should also work if you want to print out the content of a variable 🙂
Thanks for these videos. They are just what I needed. Nice job!
Good Job,
Wonderful! Thanks for the lesson, and the sub-titles were appreciated too.
Great video series. Thanks a lot.
Unfortunately the image quality is very bad and it is very dfficult to read and in full screen it is very unsharp.
Would you mind uploading a high quality version?
This was exactly what I was looking for. Thanks!
