Omg! Now I understand it very well...thx heaps for very well organized information and clear explanations. Before I found your videos, I just want to run away from R class😖..without any of programming and statistics background. Am so lucky I found these videos before my exam..oh dear lord..thx Quarantine
I believe that there is no need for dimnames to have (m) in the argument, because the dimnames is already an argument of your matrix "m". You would be right if you would add dimnames after the matrix was created :))
I'm trying to understand what it means for a matrix to be able to contain only one atomic type. Because during d tutorial, you used the "rbind" and "cbind" function to merge both character and numeric data set in one metrix. So how do explain this. Because that is a single metrix with two different data types
when ever we are declaring matrix and when we need to set byrow = True then in that case True always be in double quotes. Please correct this at 2:10 seconds of this video time. Correct syntax is: matrix(1:6, nrow = 2, byrow = "True")
Hi! Thank you for your message. With regards to the syntax that is used in this video, you'll see that the documentation (www.rdocumentation.org/packages/base/versions/3.4.0/topics/matrix) prefers a notation without double quotes because the class that is expected is a logical one and not character. :) Hope this helps!

My man! Thanks for these organized, concise, STRAIGHT-TO-THE-POINT, ZERO BOOLSHHT tutorials. You guys understand the importance of clarity and time.

May the Force be with you))) Thank you for great and up to the point lessons))) it is very helpful)))
Thanks so much for these really helpful videos!
thank you!
Ay thanks a lot!! That was so helpful , thank you very much
Thank you
tysm sir i was jst mad for dis video thax a lot
Great videos. Thanks!
Great job! thank you
great lectures ,thank you
one minor slip up, I think at 4:47 the dimnames should have the matrix m as argument. dimnames(m)=list(c("row1","row2"),c("col1","col2","col3"))
yes, thats correct. He put one extra bracket.

can I make the rownames bold, or make the line separating rownames from actual values bold?I need to distinct the names from the actual values?

they were coerced automatically, so the numeric data turned into character data.
Actualy matrixes can have more than 2 dimensions. Not sure if this is correct in R.
I have the different variables data in a single column, how can I convert these variables in different columns?
How to create a matrix from inputs by user?
