Hi, SPSS Factor method (Analyze > Dimension Reduction > Factor) can display the loading plot for two first components (the option is hidden in Rotation option dialog). It's very helpful to teach PCA. Is it possible to add this option to Jamovi Principal Component Analysis from Factor menu ? MEDA (Fa...

Scatterplot with labels

Hi, I often use the Scatterplot function from the scatr module, but I sometimes miss the ability to add labels to points (from a text/nominal variable), eg to display country names. Using the color/group field gives chart not easily readable with more than 10 values. With R, I would use ggplot(df, a...

Problem with snowCluster/LDA on Mac only

WIth the lastest version of jamovi (2.4.8 ) on Mac (M2 and M3), the latest version of snowCluster/LDA (Linear Discriminant Analysis) doesn't work. More precisely, it works with 2 covariates bu...

Re: Multiple Response Module

Jonathon,

I'm sorry about that. Option variables must be dichotomous variables (0/1 by default). I've included a sample dataset in the new version available at GitHub.

Re: Multiple Response Module

Thanks Maurizio for your help. Actually, I found an easier and more straightforward way to do it : use a menu with some preset sizes. I'll modify is later today.

Re: Multiple Response Module

Thank you very much. I already included your suggestions... but, you know, the min/max values in a.yaml. I really don't like the error message it shows to end users, which looks like a bug in the R code.

Multiple Response Module

Hi, I build my own module to deal with multiple response questions (n dichotomous variables 0/1) displaying table and bar chart... before I noticed UFS is also available as Jamovi Module. My R code uses a few lines from UFS/MultiResponse code, but since it has more options and includes a bar char, I...
