I'm a college student started to learn R. I asked my brother who's a software developer if he has a friend who's using R, he said that's a 70 year old language nobody uses that. Is that true? Am I wasting my time?

Why does the R community hail ggplot2 while there are much better alternatives? ggplot2 is horribly unintuitive. To make a pie chart you have to add coord_polar() to actually make the pie chart, to make the same in plotly you input, "type = 'pie'". Changing the axis/legend items on ggplot2 is akin to finding the cure for cancer, and don't even get me started on scales... Finally, plots made in ggplot2 looks like it was created using Excel2007. The two alternatives I have been using recently with significantly more success and less frustration are Plotly and ApexChart . They both look more modern and with the added bonus don't come with the headaches that come with ggplot2. Okay rant over, so please tell me why the R community worships ggplot2?

Hi,

Is anyone confident in using sf package in R that could help me?

I'm planning on writing an intro to R textbook! Please consider supporting my kickstarter campaign (starts April 1st)!

https://www.kickstarter.com/projects/billyl320/an-introduction-to-r-for-non-programmers

In need of help to perform the following tasks on a dataset

- Data cleansing- KNN- Bayesian- Model evaluation (e.g. k-fold cross validation, sensitivity, specificity, F-measure, receiver operator characteristic analysis and area under the curve).

Price to be agreed

Cheers

I'm a marketing analyst of 6 years who has somehow managed to get into a senior position without any knowledge of data analysis tools more advanced than Excel. But the jig is up - I've accepted a position that starts 2 weeks from now under the guise that I'm "fluent in R". I need to learn R, and fast. Also, I'd prefer not to pay an arm and a leg for it. Does anyone have any specific suggestions for how I can accomplish this goal and not make a complete fool of myself on my first day at a new job?

Or really, don't watch any videos about anything if you actually want to learn. In my experience, Youtube is full of videos by people who are good and fast at something pretending to teach you how to do it just as well and fast when in fact they're just showing off. Without even meaning to. And then there are those who are bad at something and are still trying to teach you, and since you don't know anything you can't even tell the two apart.

When you want to learn, use written documentation and tutorials, which es especially easy in anything related to programming. People who write good code also tend to write good English.

Simple rules:

1. When you want to learn about relationships and sex, don't watch porn.

2. When you want to learn about anything else, don't watch Youtube.

Hi all, I am not a coder or anything like that. My professor has an assignment using RStudio. How do I generate an object in R with 100 random draws from a standard normal distribution? Sorry if this is a dumb question lol. (SOLVED! thank you all for your help!!)

Hi everyone,

I’m looking for someone who’s familiar with RStudio and can help me clean the data from my thesis survey responses. It involves formatting, dealing with duplicates, missing values, and making the dataset ready for analysis (t-test and anova). I am completely lost on how to do it and my professor is not helping me.

This is a paid task, so if you have experience with R and data cleaning, please feel free to reach out! Need it ready for Sunday. This help would save my life 🥲

Thanks in advance!

I have a sample of 5, 17, 4, 10, 2, 45 How can I order this sample in R and calculate the mean? I am new to using R and I have tried different things and it does not work. I know I can use a calculator and calculate it quickly but I Want to learn how to use R. Thank you

Hello guys, i am trying to learn R, but unable to find well structerd documentation for libraries, in python if you look for pandas, you have the official website which includes all methods and functions with examples and all in one place, but can't find similar thing for dplyr for example, everything is spread right and left, and can't find my way. please help if i am missing something.

Does anyone have any material into how i can use AI inside rstudio? Haven't found many intuitive tutorials so i came here looking for something mores straigth foward.

print ("Welcome to my computer quiz! ")

playing = input("Do you want to play? ")

if playing != "yes":
    quit()

print("Okay! Let's play:)")

answer = input ("What does CPU stand for ?")
if answer == "central processing unit":
    print ("Correct!")
else:
    print("incorrect!")

answer = input ("What does GPU stand for? ?")
if answer == "Graphical processing unit":
    print ("Correct!")
else:
    print("incorrect!")
answer = input ("What are the type of cooling? ?")
if answer == "Liquid and Air":
    print ("Correct!")

answer = input ("What is a psu ?")
if answer == "Power Supply Unit":
    print ("Correct!")
else:
    print("incorrect!")

    print ("Thanks for playing. Made by Pablo")

Not part of the code. This is my first project, and it's played in the VS terminal. Please, no hate.

I'm in the early stages of learning R. My friend said that learning R isn't worth my time because AI is taking over data analytics. Thoughts?

How to I direct my learning to include AI?

I think I've actually never used "<-" in my R code, and I've never noticed any harm in this.

Couldn't the R community abandon this? Even for the new stylistic guide, I think that "=" would better server programmers than "<-"

I've found tons of articles about this, but I'm just a beginner with no programming experience so they are all waaay over my head. Something about comparing vectors and dfs with other data types? I'm totally lost. Can somebody please dumb this way down for me?

In this case I'm using it with filter as part of the argument:

filter(site %in% c("Site1 name", "Site2 name"))

Is this just telling R that I'm using a vector as an argument? If so, why is that even necessary?

I need to generate 50000 samples from a certain distribution and for each sample calculate several confidence intervals for a certain parameter and check whether the true value of the parameter falls in the confidence intervals and the width of the intervals, then at the end compute the coverage probability and the average width for each method, and i need to replicate this for various sample sizes

I know how to do this with for loop but it's painfully slow considering one of the method is bootstrap and there is a for loop even there.

I have three for loops one for sample sizes one for the 50000 reps and one for bootstrap, i know for loop is slow in r but i don't know any other alternatives

How can i optimize my code ?

Hola buenas, les comento mi situación. Estoy por rendir una materia libre ya que no pude cursar todas las materias por el tema del laburo. el problema comienza con la profesora que no le gusta que rindamos libre y me dio un problema a realizar con el programa Estadistico R, el cual ella no enseña en la catedra. Tengo algo de idea pero tengo tan poco tiempo para hacerlo que no se si llegare. mi pregunta es si alguien me puede ayudar , se lo agradecería. o si conocen a alguien que trabaje con eso y le compro lo que seria el ejercicio? muchas gracias.
