RfastOfficial / Rfast

A collection of Rfast functions for data analysis. Note 1: The vast majority of the functions accept matrices only, not data.frames. Note 2: Do not have matrices or vectors with have missing data (i.e NAs). We do no check about them and C++ internally transforms them into zeros (0), so you may get wrong results. Note 3: In general, make sure you give the correct input, in order to get the correct output. We do no checks and this is one of the many reasons we are fast.

Rfast::Dist() causes Rstudio-Tab call of doc to freeze the app until kill #19

Melkiades commented 4 years ago

So, it has been a nightmare because it is very hardly reproducible and it was since a bit I added Rfast (which is incredibly fast, thanks for that :) ) to my work pipeline. This freezing happens on Ubuntu 18.04 LTS and Mac OS X catalina with the latest versions of R, Rfast, Rstudio and tidyverse. To reproduce the error, it is enough to run Rfast::Dist() or to attach the pkg to the environment and to Tab complete a function from tidyverse like mutate_all and this freezes Rstudio completely!

I hope it is reproducible with this degree of precision! I do not know what is the problem, but could it be a documentation related loop? maybe related to the fact that Dist is too similar to the rbase dist?

Thank you for your time and sorry if the problem was already, for some to me unknown reasons, solved.

Can you give me an example? I have never use tidyverse package...

Melkiades commented 4 years ago

yes, it is enough to run the following: library(Rfast); library(tidyverse) and then take a function like mutate_all() and try to tab-complete it and to press again tab to call the function variable documentation and Rstudio freezes until killing. This is somehow connected with Rstudio because just from terminal it is not freezing the session.

Hi Melkiades, this is Michail. I tried what you said in R and it works perfectly fine. But, when I pressed the "tab" in Rstudio it jammed. I will agree with you, this has something to do with Rstudio.

I test it in my laptop with last version of R and Rstudio and it works fine. Maybe it is Rstudio.

I sincerely doubt it. I made a video of what still happens in R 4.0.0 (version of 5 days ago), Rstudio 1.2.5042 (latest version, 28 days ago). Also, I run everything on the latest Catalina (10.15.4). In addition, the problem is still present also on Rstudio server and on Ubuntu 18.04 LTS.

I am aware it is not directly your problem, but, as they said the problem is still present in the dev version of Rstudio 1.3 and as many of us code using Rstudio, I would keep this issue open. I mean it is completely impossible to use Rfast on Rstudio... must be something to keep an eye on isn't it?

I attach a 1 min video that can show you what happens (what you do not see is that I press tab many times).

In my laptop it is fine. Tidyverse shows conflicts about same functions on different packages. Personally in C++ it is a bad practice to use library mechanism because of those conflicts. Although I use it for readability. These conflicts might be the problem. Generally, when I run library ("tidyverse") it took one minute to finish. Jesus... A lot of time for a small thing... But it checks for a lot of things as you see. Sometime, I waited and I thought that there is a problem but eventually it just needed time. I don't know what to tell you...
