Loved that at 14:00.

A good tutorial by the way. Nice clarity of video and audio quality makes it easy to focus on content.

Now I know the relationship between yawning and R. R and yawning are inversely proportional.

This got me smiling throughout... I actually enjoyed the video! :)

Thanks for yawning in my ear. Good stuff.

hi delta DNA can I ask a question on plotting please

[ismaielahmed]

if i have categorical values like (Bad, Good, V Good, Excellent) .. How i can order those values in Histogram bar plot ...

[lexh]

im using R for powerbi, and i have a looot of columns with spaces, how to deal with spaces ?

[benjlopez]

Hi! Should I still use the query for the CSV file I got from the link?

[ayodejiologun]

@deltaDNA, I could see that you have an overlapping values on X axis at 12:32. How do I deal with this as i have the same issue.

[a.e.mahamedi]

Thank you so much for the very useful video.

[Hey-mjjg]

set.seed(10)

library(data.table)
tabulka = data.table(A = rnorm(10),
B = 1:10,
C= 10:1,
D= rep(c("a", "b"), each=5)
)
tabulka[2, 1]=NA
tabulka[4, 1]=NA
tabulka

tabulka[c(1, 3, 5, 6, 7, 8, 9, 10), mean(A)]
tabulka[, E:=B^2]
tabulka[, F:=sum(B), by=D]

Thank you for your video tutorial! I have a quick question. If my data size is over 1GB, and if they are a number of data columns, rows, attributes to be shown on geom_bar() or geom_point(), how would I set the range of those data on my projection? Thank you in advance!

[jennaproctor]

So I want to plot different stress and food factors along the x axis and distance along the y how do I go about putting this in the the script you showed? I didn't really get how you scripted them

[jayjayf]

Tell your boss to allow you to sleep, so your not yawning all the time

Hi, out of curiosity where's your accent from, you really pronounce the H in 'what', 'which', etc., thanks for the tutorial also!

[dpippatan]

I can't seem to find the downloadable data and tutorial after signing up for the page. Could you advise? :)

[punchline]

Recording in R-tutorial while being so tired is kind of dubious.

[Kampfus]

All the breathing into the microphone made id VERY hard to stay focused. Other than that it was a good video.

[MarcusSanchez]

Does somebody else head hurts really bad at the beginning on this video or is just me?
