Hey Bucky when are we going to get the other videos about stats and graphs and all that good stuff 😉

They Pheaktra says:

Nice tutorial.! Please will make “Hadoop Tutorial”.

Oneironaut says:

Hey Bucky, I’m a new subscriber and I just want to tell you that I appreciate this tutorial. I have managed to get my brother who is a scientist in the field of biology to watch the first few episodes. Most scientists suck at programming and statistics so keep this up and we might be able to contribute to something bigger… like a non-sucky scientist :)

Bucky, can you teach us Lua? Several games use this scripting language such as Gmod, and ROBLOX, and apparently Dont Starve. so does WoW.

Bruce Levy says:

First time with R going through your videos. How do you all remember all these commands and stuff?

asqn007 says:

It is also possible to just write F/T instead of FALSE/TRUE and everything will be the same. Plus you can use read.table function that can also make the same data.frame and I hope you will show attach function next time (just a small hints)

I really love your tuts and I hope I will learn much more from your vids. You are making this world better! :)

Couple notes
1. Excel files have multiple pages, but CSV files may only have 1
2. The CSV must be formatted such that only a header and columns of homogeneous values are present (he alluded to this already by saying it will be read as a data frame rather than generally as a list)
3. The data frame and CSV will not save formulaic data from an Excel file, but rather just the final numerical output of those formulae to each cell
4. Obviously, it also doesn’t save any aesthetic changes to the cells or font, so a lot of data may be lost in this transfer if the original file is Excel
5. CSVs cells also are not able to refer to cells from other files; they’re kind of dumb in general.

GOURAB DASGUPTA says:

Here’s a linear regression of the CSV file that used in this tutorial:
————————————————————————
csvFile <- read.csv(“D:/Projects_Programming/R/brUsers.csv”,TRUE,”,”) plot(csvFile$age, csvFile$income, xlab = “Age”, ylab = “Income”) ageMean <- mean(csvFile$age, na.rm = T) ageMean abline(v=ageMean) model1 = lm(income~age, data=csvFile) abline(model1, col=”red”) summary(model1) —————Have fun———————————————- =D
