Very helpful. GOD bless

thank you very much for your help mr Marin, your videos are very clear and helpful, am not desperate any more, it took me days and years to find someone that can remind me how to use R again, you are an angel from above

Hi again, and thank you for your really good neutral pronunciation and slow speaking, for the non english people is a plus. +10!!!

Thanks Marin…this makes it easy to learn R

sir, i am really fortunate to get hold of this course.can u post more videos for logistic regression analysis , clustering and decision tree in r . please

very useful to us thank u so much

Hello Sir, Myself parminder. Im good in excel now i came to know about R importance future in companies. i want to know more about R. I saw your videos till 3rd . its very interesting and valueable. i want to know can u send us assignments for begginers so that i can do practice at home.

how can i download the excel data that is being used in this video ?

How to subset both the diagonals of a matrix?

#MindBlown! How are you so good at explaining! What’s more awesome is being able to select the essential things that need be learned by a novice. Thank you!

Mr. Marin, wonderful videos! Quick question, why does a vector yield a ‘numeric’ type but a sequence yields an ‘integer’ type? What is the difference? Also what is the ‘short hand’ for selecting the last element in a vector? Thank you!

At 8.32 it says you can extract Column, but it prints in row fashion. I think this is incorrect representation in R language. Mathematically, the slicing should yeild column vector not its transpose.

I don’t know if it is already in a video or not, but I didn’t find it, so could you explain me how I could add a column in a matrix that was in a data that I already imported on R?

Sorry for my english.

And thanks a lot for your videos.

amazing, great explanations. Actually I had a course today and I was very confused , thanks for help.

Thanks a lot !!

While we save the file as .Rdata and next time when we load how do we check the comments which we added ,, when i load and open i can just see objects in my workspace

Hi Martin I find your videos really helpful, thank you. I wanted to ask you, how would do you select individual numbers from separate rows and columns in the matrix ? is this possible ?

very clear and helpful tutorials , great progressive explanation, thank’s !

iam beginner for R programming i need how to write code in R

Hello sir, ur videos are really helpful to me as i’m in learning phase right away. but the thing is that, how i could able to apply these things to some sort of complex assignment??? could u pls help me out on this regard.

very informative….

hello I’m new to R.

can you explain why R is used, when Matlab exist? Is it only because it’s free, or has other potential? thanks 🙂

so, one quick question if two commands are synonymous how do you represent it using the R program? I.e. c(3:9) is equivalent to (rep(3:9, times=1)), both yield the same answer for lets say a command y, can you type it in such a way the R program reads it and understand they are both the same answer just expressed differently.

The choice of “c” is for concatenate? When I first saw this, I kept thinking it represented the word “column”, as in column vector.

Very nice job, Mike! I enjoy these tutorials.

interesting and really useful, thank you +Marin for posting, can you pls explain the concept in video 7.37 i.e extracting matrix in row and column i am not able to follow that.

I love your videos. I am new to R programming and they are very helpful and much easier to understand . Great work.

Hi sir will you please upload R programming videos not R studio videos

Hey sir,

Its my second tutorial..

Its really help a lot and very effective

Each and every step was clear..

Thanks and teach us more about R (if there is more things which we need,except uploaded videos)

THANK YOU!
