Experiment not running online on Pavlovia

[Khushbus21]

Hey, I wanted to run your experiment online on Pavlovia but after starting it gives an error, Just after the clicking spacebar on the instructions page. Can you help me solve this, please?
error statement:
ReferenceError: stimuli_count is not defined

Hi @Kbs21 thanks for reaching out! Can you share with me your PsychoPy version? (Asking because there are some version related incompatibilities with complex span as reported in #3)

[Khushbus21]

yes sure, my Psychopy version is 2021.1.4

Did you make any changes to the experiment file that you downloaded on this repo? Seems like the initiation of stimuli_count was not properly done before the first phase (presentation of individual letters) started. Can you check if stimuli_count is set to 2 under "Begin Experiment" in the customized code component under the show_letters routine?

Otherwise, you can try updating to the latest PsychoPy version 2021.2.0 here: https://github.com/psychopy/psychopy/releases/tag/2021.2.0

[Khushbus21]

Yes, it is set to 2. I did not make any change to this repo after downloading it.

Also I have one more issue, I am trying to run the source on R studio and it gives this error :

Can you please help me figure this out, there is no extra '<' in the code, the code is from your experiment description, the first step-" # Download the function used to preprocess the data " part.

Could you upgrade your PsychoPy version to the 2021.2.0 and let me know if this works? (It should since it's working on my local copy using the latest version)

Regarding the source code error, could you

1. set the working directory of your R script to the statistics folder of the repo ("../ComplexSpan/statistics")
   and
2. try with source("preprocessing.R") and source("processing.R")

Hey, thanks for the reply. It turns out that easystats ecosystem is currently undergoing a bit of restructuring, and this is the reason why I can't download the packages (I'll have to wait until easystats/effectsize#361 is merged).

For now, it is recommend that I download the needed packages from CRAN. Can you please help me with the required packages

[zen-juen]

Hi @Kbs21 the easystats package is needed only if you want to produce the figures using make_figures.R in this repo, but otherwise to run the preprocessing and processing scripts you can simply install.packages(c("tidyverse", "dplyr")) before running the code 😄

[Khushbus21]

Hey, I am getting this error on using process_WM function, can you help resolve this, I tried resinstalling packages magrittr and dplyr but the session gets aborted or it does not help and gives the same error.

process_WM(path_to_csv)
Error in dplyr::mutate(data, Span_Simple = max(Simple_Task$Set_Size) - :
could not find function "%>%"

[zen-juen]

if you have tidyverse installed already, could you run library(tidyverse) before running the source code?

Thanks a lot for your help, it all worked :)
