Basics of R Dataframes! Subsetting, Columns, Ifelse

[billybob]

Thank you!! Watching your video first would have saved me the past two hours of searching Stackoverflow

[PutBoy]

Damn, did I just learn everything I need to know about Farenheit?

What's with the 4chan man beard + stache combo?

In your example where you had columns with different formats of the same data, e.g. one column with celcius and another with fahrenheit, you hardcoded both of the columns, so if one column for some reason had to change the other one would also have to be changed to preserve the relational integrity.
Do you know if it is possible to have one of the columns be a logical column that "under the hood" calculates its values from the other?

What do you think about making videos on python's data science stack including pandas, numpy and so on?

[tanko.engineering]

Fahrenheit 0 is "really really" cold on a cold day, 100 is "really really" hot on a hot day.
"Really" means nothing. It is subjective and does not really relate to anything in reality.

Celcius 0° is the freezing point for water and 100° is the boiling point for water (with a fixed, constant pressure and whatnot).
Objective, reproducibale, standardized & uniform (0 & 100 --> 0 - 1, 0 - 100%, ...) and therefore more useful for engineering & maintenance of complex systems...

Kind regards!

Literally "how to obfuscate good measurements" tutorial!

Couldn't you have just done time mod 1200?

[michaelrivera]

0 in F is about as cold as it should ever be if nature were to oblige us, and 100 in F is as hot as it should ever be if nature were to oblige us.

Your arguments about Fahrenheit vs Celsius are completely pointless.
It's not a matter of comfort. Comfort comes with use. I mean, what's more intuitive about 100 compared to 37? They're just numbers.
You should use Celsius because it's a standard. Not doing so on the internet, è come scrivere in un'altra lingua quando sai benissimo che quasi nessuno ti può capire.
I thought computer guys could understand such a concept.

*How am I supposed to know 2am or 2pm after conversion.* :D isn't that a loss of information, but anyways.. _Thank you very much for all the effort you've put into this turorial._

[saigon]

Unsub how can you use illogical temp unit... :D

[ali-omuv]

have you explored python with pandas and or numbapydata ? I switched from are as a general pursue language just offers so much more. nice video btw!

[syedasameezahra]

Hi ! Your video contents is epic, I wan to ask you about ( dlnm package 2.3.4 that is of R 3.3.4, ) onebasis and crossbasis I cant grab them all as it is stated in pdf of dlnm 2.3.4 can you plz explore that how to build two crossbasis matrices and saving them in two objects below are the lines of the pdf I run crossbasis  () to build the two cross-basis matrices, saving them in two objects. The
names of the two objects must be di

erent in order to predict the associations separately for each of
them. This is the code:
> cb1.pm <- crossbasis(chicagoNMMAPS$pm10, lag=15, argvar=list(fun="lin"),
arglag=list(fun="poly", degree=4))
> cb1.temp <- crossbasis(chicagoNMMAPS$temp, lag=3, argvar=list(df=5),
arglag=list(fun="strata", breaks=1))

Wow, nice trolling F vs. C people ROFL..

btw, using your "if" condition; 1259 is still 1259 in a twelve hour clock ...

[crtnnn]

just discovered your channel. too bad you only had like 3 ten minutes videos on

Celsius < Fahrenheit < Kelvin. GOML
