How you get those tabs on the side that shows your variables

Hi, Mike! When I downloaded R, in addition to the x64 R icon, which I was expecting, it created an i386 icon. What purpose does this have, and can I get rid of it?

I m frank to say very easy to understand this

Thanks for this amazing video, from now R will be easy and interesting

I have a question the right part (workplace,files,….) in this video I can’t see , why?

I think I understand object-oriented programming, but why are variables referred to as “objects” in R? In statistics, we have random variables, not random objects. It seems like an odd detail that does not appear necessary. Thanks, Mike!

wow.. Great Tutorial.. Thanks

I have downloaded R but in my R screen , workspace tab is missing. Kindly help.

wow R seems to be much more easier than c++

Thanks

very nice tut! good job!

# Thanks Marin very useful and appreciated.

I seem to somehow can’t see the workplace/ history column nor the file/package/plot/help column. I down loaded both August when I started Statistical Science and I’ve been intrigues to use R since then but I had to drop the course because I found out i didn’t have the pre-requisite half way into the course. Can I get some help please on how to get those two additional columns ? Did I do something wrong? or Is it that that’s how R look on mac pc ?

Thank you, well done

Thanks for this useful tutorial.

Thankyou so much sir, I just Installed r a couple of days ago in order to go through the basics, this video has really helped me in grasping them. thanks again!

how to open the workspace window in R ? and one more thing, that if I use R and not R studio, would that be ok ? Thanks in advance.

Great video!

Thank you for your tutorials!!

+MarinStatsLectures This is the best R tutorial! I’ve been looking around for R tutorials and you nailed it! Better than Coursera’s R Programming course!!!

I’m new in R. These videos help me a lot. Thank you so much.

great work…i dnt have words to appreciate u more sir..:)

Great tutorial! Though I recommend speeding up to 1.5 for anyone watching

very useful, thanks a lot.

You are Awesome Marin!!!. Really great videos…Short and sweet.

Thank you Mike! You saved my statistics course

Perfect!

i m very new to R so can you just explain why log value in R and in calculator not same? I mean log for 9 in R is 2.19 whereas in calculator its 0.95

THANKS A LOT – very nicely explained.

Great tutorial!

Спасибо за видео

thank you so much, it was so helpful.

how do you save the RStudio console? so you don’t loose the data

Hi, Thanks for the useful tutorials. I just started using R and I still don’t know for example how to create a file in R or to save it and this kind of basic stuff. I’d really appreciate if you could tell me in which video can I find this info.

This video serves as a very effective and brief introduction to R. I like that this video covers a lot of the common operations that can be performed. This makes it effective for those who have experience in other programming languages so they can see how the R syntax differs. It also provides a good introduction to the basic steps of programming in general. The only downside is that it would be nice to introduce those new to R where they can find the software, and also the differences in the R download from CRAN versus RStudio. I think new users can benefit from using RStudio due to the argument hints and familiar interface. Thanks for posting!

great explanation thanks

very good one its help me a lot thank u marin

thanks a lot.

I cant see the Workspace on my right side of the R-Studio.Do you help me to work this thing out?

Excellent job! But I will like to point out that, when you have x = 11, 11 is the object assigned to a variable x. But you said x is an object assigned the value 11. Objects in R include scalars, vectors, matrices, arrays, lists, graphs, e.t.c. In fact whatever can be assigned to a variable is an object in R. Thank you.

This video was downvoted by two pirates who thought they were learning ‘Arrrrrrgh!’

you are amazing

A very clear explanation of some basics! Thank you so much Sir!

Hi Marine! I am a novice learner of R. However, I am hell bent on learning R as it is a great software which I can put into use for my econometrics studies. The videos appear great to start with. Any tips, you would like to give to me Marine?
