I'll be presenting the research design for my second PhD project during the PYMS Online Lunch Meetings next week

(and there are also many other very interesting presentations lined up)

Sign up to attend!

Short overview of program of the online lunch meetings.

Registration is now open for our online presentation series!

Every day from April 20–24 (12:00 CEST), two ECRs will present their work. Finished projects, raw ideas, and everything in between

#preprint

In our new preprint, "Collaborative Grant Writing: A Successful Case of Coordination in a Funding Application", @lakens.bsky.social and I describe how 12 members of the Netherlands Metascience Coalition (a group of 20 researchers across 12 Dutch universities) came together to develop two

how many tools and explanations exist for making code reproducible (or at least for sharing package and R versions), yet I can't find a single clear overview of what to actually do with that information across different operating systems, or how to solve the common errors that come up. [2/2]

Yes, I know it's possible. But take the R version as an example: once you know it, you also need to match the Rtools version on Windows, a compiler on Mac, and something different again on Linux.

All of this is possible of course. But it surprises me ... [1/2]

Any good resources on reproducing the R environment of somewhat old code?

There's material on how to make your code reproducible, but little I can find about how to reproduce code written in an older R version, with old packages etc.

Sounds easy, but seeing more errors than I would like

Awesome, this is what I was looking for! Will definitely test it out today, thank you for sharing!

Right? Seems like a missing link!

It’s doable to write something like that sure, but I would have just expected there to be a basic counter function to the sessionInfo() one already

Yes I always use renv myself! But I wanted to reproduce an analysis by someone else who only shared sessionInfo() output. So then I wondered if there isn’t an easy way to automatically update the environment using that output

Yes, packages in the right version, and ideally also the R version

For basic reproducibility sharing sessionInfo() output is sometimes recommended

But I can't find a function to automatically install the right package version (let alone R vers)

Do you install them by hand? Write own code to install automatically? Seems cumbersome for output that is standardized

We examined reporting- and open science practices in simulation studies in psychology with a questionnaire

Importantly, we asked ‘why?’

Why were results omitted? Why weren’t MCSEs reported?

Also: how do researchers evaluate simulation studies in their field?

🧵

I've talked about this with some of the developers here at the Bennett Institute over the years and they don't think CC is a great fit for code and while MIT isn't perfect, it does the job better. Honestly, we probably need some legal minds to come up with a new license type for open science usage.

That’s perfect thank you!

Yes, because the code is not really 'software' it is shared for reproducibility

As far as I understand, no license strictly means that no one could ever use the code again (does that also mean to reproduce the paper?)

Because I want people to be free to do whatever with it, I wanted to license it

Ah thank you!

So what license do you use for analysis code that belongs to a paper? The MIT license?

On Github, the CC by 4.0 International license is not one of the standard options when creating a repository.

Does anyone know why that is? Is the MIT license more appropriate for code somehow? Permission to sell seems so strange to me...

But I know rather little about licensing #helpmechoose

It's been a week, but we left inspired after #PSE8 in Leiden.

Thanks to all who participated in our mentor-mentee lunch! Hopefully you all had interesting conversations, and made new connections.

Leif’s #PSE8 keynote was ridiculously good, basically a live episode of @datacolada.bsky.social ... if anyone deserves a detective/sitcom series based in their work, it’s Leif, not Ariely – take note @netflix.com

Thanks to everyone that was interested in my poster for the great conversations and discussions!

The preprint on reporting, open science, and trustworthiness in simulation studies is available here: osf.io/jn9sy_v2

Ready for day two of #PSE8!
