# R Functions List (+ Examples) | All Basic Commands of the R Programming Language

There are thousands and thousands of functions in the R programming language available – And every day more commands are added to the Cran homepage.

To bring some light into the dark of the R jungle, I’ll provide you in the following with a (very incomplete) list of some of the **most popular and useful R functions**.

For many of these functions, I have created **tutorials with quick examples**. Just click on the function you are interested in, in order to get more information.

Let me know in the comments, in case you are interested in any particular function. I’ll try my best to publish a tutorial for this function as soon as possible.

Hi Joachim, the compilation is getting better day by day. Small suggestion, in the list of R Commands & Functions can you please add Tidyverse grammar such as “pull” etc.

Thank you

Nara

Hey Nara,

That’s great to hear, thank you! π I am planning to do a series on tidyverse functions soon. I’ll keep you updated on that.

Regards,

Joachim

Hey Nara,

As promised, I have produced a series of tutorials on the dplyr package. You can either search on this page for [dplyr] or you can check out this page: https://statisticsglobe.com/dplyr-r-package

Regards,

Joachim

Muchas gracias por todo el material que publican. Un gran trabajo. Felicitaciones

Muchas gracias Oreste! Nice to hear your positive feedback!

Hi,

It would be nice to add the “subset” function to the list.

Hi Ali,

Thank you for the suggestion!

I’m planning to do a series with new R-function tutorials starting this week. I’ll also include a tutorial on the subset function to this series.

You may follow me on Twitter to get regular updates on the newest R-function tutorials: https://twitter.com/JoachimSchork

Regards,

Joachim

This is great! Thank you. Could you include the switch command and information on how to write functions within functions lines of code (if not done already; I did not check for that)?

Hey Cessar,

Thanks a lot for the nice feedback!

Actually, I have created a tutorial on the switch function just a few days ago and haven’t added it to the list yet. You can find it here: https://statisticsglobe.com/switch-function-in-r/

Could you elaborate what you mean with “how to write functions within functions lines of code”? I’m not sure if I got what you are looking for. π

Regards,

Joachim

I am still wondering why anyone would take the effort to try to use an archaic programme like R. A command prompt? We are living in 2020 and not 1980. Why not use Excel? For anyone not used to typing commands and programming it is a disaster which leads to frustration also caused by thousands of add-ons which is the reason why copying commands in tutorials and examples does not work because you just havenβt downloaded the right add-on.

Hi Cristo,

Thank you for your comment and your thoughts.

In my opinion, there are numerous reasons for both R and Excel and I think discussing this here in detail would be beyond the scope of this article.

However, you can find many discussions that are highlighting the pros and cons of both programmes:

https://www.northeastern.edu/graduate/blog/r-vs-excel/

https://www.rforexcelusers.com/excel-vs-r-when-to-use-what/

https://www.quora.com/What-really-differentiates-R-from-Excel

Personally, I prefer R since I like to control everything my software is doing in a script. One thing I don’t like in Excel is that it often formats data automatically without telling the user (e.g. numeric data to dates).

However, as I said I think both softwares have pros and cons and in the end this heavily depends on personal taste.

Regards,

Joachim

Hola Joachim. I just want to add on your comment to Cristo: you have to decide if you want to be limited on what to do, but in an easy way (Excel) versus doing what you really want to do, with some extra work in R (not much extra work thanks to people like Joachim). Best.

Hola Denny,

Thanks a lot for these additional thoughts. I definitely agree with what you said.

Also, thank you very much for the kind words! π

Regards,

Joachim

Great tutorial thank you for sharing

Thank you for the kind words Rajesh!

Hi!

This side is very nice and helpful! Really good job, specially on the examples.

Maybe you can link the functions. F.e. when you use the mean function in your aggregate example you can link it – so it gets easy to click through your list. By now this is not a big problem but it might get if you include others from different packages. It also might create a more connected learning.

But nevertheless really love your page!!

Greetz

Simon

Hey Simon,

Thanks a lot for the kind words and the feedback!

In fact, I already try to include links to other functions in case I’m referring to them in a tutorial. It is sometimes difficult to add links to older tutorials when publishing a tutorial about a new function though.

I have added a link to the mean function within the text of the aggregate tutorial. However, please let me know in case you spot other missing links! π

Thanks again!

Joachim

Hey Joachim, Very useful content.

Have one query, is there any library or package where we can perform goodness of fit test and estimates its parameter for the following distribution

List of distribution

1. Two Parameter Exponential

2. Two Parameter Weibul

3. Smallest Extreme Value

4. 3 Parameter Gamma

5. Logistic

6. Log Logistic

Hey Vijeyachander,

Thank you very much for the kind words! π

I’m not an expert for this topic, but maybe the EWGoF package helps: https://rdrr.io/cran/EWGoF/man/EWGoF-package.html

Regards,

Joachim

This appears as a useful listing. Could it be organised to subgroups? Like data manipulation functions in the same group, probability in one group etc.

Hi Juho,

Thanks a lot for the feedback! This is something I have planned for the future, and I hope I can realize it soon.

Regards

Joachim

Wow! This is amazing! I just started an R Class for a Business Degree, having no knowledge of computers, and was so confused. Thank you so much Joachim! May your life be blessed!

Thanks a lot for this awesome feedback Lewis! I’m very glad to hear that you like this list! π

Regards

Joachim

It’s amazing

Thanks Lawrence! π

Well written. π

Thanks a lot Tulsi, glad to hear that! π

The use of class() is useful to me when establishing the type of variable we e.g. data frame so is it eligible to be included? The list does look to be useful. Thank you for this accomplishment.

Hey Angus,

Indeed, the class function should be on this list. Thanks for the hint, I will add it soon.

Hey Joachim,

I am writing a package for r and possibly python and found this list in my research. I realize this is an older thread, but you seem to be active still. The package is pretty simple and I would love to get your input on it.

Hey Craig,

I have never developed a package myself, so I’m not sure whether I’m the right person to ask. However, do you have any specific questions?

Hello….. How is it possible to find the oblateness and skewness of the Weibull distribution and the Beta distribution

Hey Wakkae,

Hey Joachim,

What an amazing website you have created, I find it very helpful! However I can’t seem to find the method to sum different elements in a large data frame. For example, this particular data frame has 500 rows and 5 columns, then I would like to find the sum of row 1 column 6, row 6 column 6, and row 11 column 6 elements. How do you think should I this?

Thanks in advance for your reply!

Regards,

Hans

Hey Hans,
