Re: Feature request: Plot multiple variables on same axes (repeated-measures data)

we might need a screenshot of the SPSS feature you're describing.

Re: plot$setSize() in .run() works interactively but fails on Export - looking for best practices

hi, yes, i would move your $setSize() into .init(). the general rule is to do as much in .init() as you can. you can also use $setSize2() https://dev.jamovi.org/api_image-sizing.html let me know if there are any outstanding issues after that. > How exactly does the saving process work? Does it trigg...

Re: Calculating mean based on different number of cells containing values

i think you're just missing a bracket on the end? IF(COUNT(v1,v2,v3,v4,v5,v6,v7,v8)>=7,(SUM(v1,v2,v3,v4,v5,v6,v7,v8)-MIN(v1,v2,v3,v4,v5,v6,v7,v8))/6, SUM(v1,v2,v3,v4,v5,v6,v7,v8)/6) not sure if the rest of the logic of your formula is correct, but this gets us passed the mis-specified error. reading...

Re: Chi-square test not working because of missing values

hi, you're right, this is a weakness in our chi-square test implementation. a work around would be to create a second variable which is a copy of the first, using computed variables. you'll see that the chi-square tests handle this second variable correctly. jonathon Screenshot 2026-02-06 at 09.57.2...

Re: Factor analysis core functions: more options for stochastic parallel analysis?

we're planning on adding a "determinism mode" to jamovi for teaching purposes. but yeah, in general statistical software has handled it pretty poorly. it's a positive that you've been able to discover that the results aren't particularly stable, where as adding a random seed would likely c...

Re: Cannot use Rj with system R

thanks for letting us know. i think Rj doesn't handle this particular combo of registry information correctly. i've created a PR to fix the issue, and i'm just waiting on maurizio to review it for me, then we'll push out a fixed version.

with thanks

Re: Cannot use Rj with system R

hi, i think there's something unusual about the values in your registry can you tell us the values of these registry entries? # Try HKEY_LOCAL_MACHINE first regHLM <- file.path("SOFTWARE", "R-core", "R64", fsep = "\\") entries <- try(readRegistry(regHLM, hive ...

Re: Questions regarding Inter-Analysis Object Sharing and Custom File I/O Capabilities

hi, 1. isn't possible (without relying on approaches that aren't kosher ... and arbitrary R objects can be difficult to work with, on account of them often ending up very huge when serialised). 2. isn't possible at the moment either, but we're not too far from being able to implement something like ...

Re: jamovi desktop keeps crashing on me error Engine process terminated with exit code 255

hi,

figuring out what's going on in these situations usually requires a forensic deep dive, and is tricky for us to do without physical access to the machine. your best bet is probably to use the cloud version:
