there is no package called 'withr'

[MCube78]

• JASP version: 0.9.2 (this bug was not present in 0.9.1)

• OS name and version: Windows 10

• Analysis:
  Attached figure 1: Binary Logistic Regression > Plots display conditional estimates > Show data points
  Attached figure 2: Descriptives-->Jitter elements

• Bug description: When I try to display individual datapoints on graphs it gives this error (this bug was not present in the 0.9.1 version)
  TEXT from JASP output:
  This analysis terminated unexpectedly.
  Error in loadNamespace(name): there is no package called 'withr'
  Stack trace
  f(...)
  with_seed_null(params$seed, transform_position(data, trans_x, trans_y))

• Add JASP files as a zip:

• Screenshot:
  Example 1 (binary logistic)
  

Example 2 (descriptives, boxplot jitter elements)

• Expected behaviour: see individual points on graphs
• Steps to reproduce:
  Example 1. Go to binary logistic regression > Plots > Display conditional estimates plot > show data points (error happens here -- see figure)
  Example 2. Go to descriptives > select some variable > Plots > Boxplot > Jitter element (error happens here -- see figure)

UPDATE: I re-installed JASP0.9.1 and, on the exact same data set, I am able to plot without an issue individual data points. So this must definitely be something that has changed between 0.9.1 and 0.9.2. I hope this helps solve it.

Hi @MCube78

Thanks for reporting this.
This is indeed an omission in the R framework package list we deliver.
We will solve this asap. As a work-around I've attache a zip file with the missing package.
If you unzip this and copy this to the C:\Program Files\JASP\R\library folder you'r problem will be solved.
withr.zip

Kind regards
