Not sure if anyone else has brought this to your attention, but the rm() function can accept many parameters (or many variables). For example... x = 10 y = 1000 z = "Oooohhh Francis!" rm(x,y,z) So for those of us writing a TON of variables and data frames (guilty!), this should speed up the process of cleaning up your environment. Awesome video!
you basically need a separate monitor open in fullscreen to follow these videos without having to constantly maximize and minimize in order to test the code. if you don't have a separate monitor it really sucks trying to follow along with RStudio opened on the side
x=8 x+2+1-1+5 i left cursor in second line. when i run this program, console window showed x+2+1-1+5 [1] 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 -1 can anyone explain me what happened here thank you
In what environment exactly do you use this language? Like, who would chose this instead of Java or C++ ?! It seems like a programming language for kids, this...
It's used in a large part of the scientific research and theoretical mathematics world, and also in economics analysis... So, not exactly for kids. Java is ancient and slow, C/C++ is often too slow to develop and iterate with in environments where you very frequently need to actually change code. C/C++ is also harder to write for little gain in some cases, the purpose of R and similar specialty languages is that you write a lot less code to perform the same task, and it's still fast.... Which is great.
It tracks his computer's performance I'm pretty certain. The higher the number on the speedometer, the more stress the computer is under from running things
These tutorials are very meat based.
I like it

Awesome video!
watching this 7 years later after publishing.. evergreen tutorial!
Dude, these tutorials are amazing, keep it up
maximize the window..... Full Screen plzz....
Thanks for these. Just started learning R. Looking forward to the rest.
It's simple but useful tutorial.
Why does assign() take "ham" as a string, yet rm() takes ham without the quotes.

Full screen video, then alt-tab to RStudio, and get rid of environment and file browser parts of the window, so you just see the editor.
greatsea Anyone who wants to program should have a second monitor. I would never think about programming without one.
if I replace rm to any other name or something then why its show
could find something
why ? How? every time i have to use rm for this type of code
x=8
x+2+1-1+5
i left cursor in second line. when i run this program, console window showed
x+2+1-1+5
[1] 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 -1
can anyone explain me what happened here
thank you
Are there videos where you explain Bitcoin?
Is there a way to remove all variables at once?
> y = bacon
Error: object 'bacon' not found
> I love to eat y.
Error: unexpected symbol in "I love"
>
That statement don't work.
Whats the forum name?
Go Bucky!!

R Programming Tutorial - 4 - Variables
Bucky - I have to know - what is that cool speedometer gadget thingy you have on your upper right side of the screen!?!?!? it's killing me!!!! :-)
It tracks his computer's performance I'm pretty certain. The higher the number on the speedometer, the more stress the computer is under from running things
why u don't maximize the window is beyond me.... gurrrrr >.<
anyways these are very helpful, thanks!
I love to eat bacon and x for breakfast
