Error in $.shinyoutput

[Jacqvb]

Hello, The Netherlands here, I was looking for a new way to do IRT analysis and DexterGUI seemed like a good place to start! However I’ve run into some problems: I use: R version 3.6.2 (2019-12-12) RStudio Version 1.2.5033 (both updated to newest versions after I suspected that the error was due to older versions)

After loading the packages this happens: --> I first open a new project, then select a file for the scoring rules (excel), following I get:

Warning: Error in $.shinyoutput: Reading from shinyoutput object is not allowed. [No stack trace available]

Could you please inform me if I’m doing anything wrong or if this is a bug indeed? If you need more info please let me know. Thanks in advance!

Hi,

It's a horrible error message certainly so that should be corrected. Not sure if it's a bug per sé. Could you include some lines from your scoring rules file to help me make sense of the problem?

Hi,

Thank you for the quick response! These are the first 10 lines, including column names:

item_id	nOptions	key
CRa_1	5	E
CRa_2	5	B
CRa_3	5	D
CRa_4	5	D
CRa_5	5	A
CRa_6	5	B
CRa_7	5	B
CRa_8	5	C
CRa_9	5	C
CRa_10	5	A

I did get an error trying to read your keys, though it wasn't the same as yours. It was a bug that surfaced because of a recent update of dplyr. Anyway, I fixed that and I hope it fixes your problem.

If you could try installing the new version like:

devtools::install_github('jessekps/dextergui')

and let me know if the problem is fixed?

Hi, thanks! I will try that later (probably this evening, I'm away from my computer today). I'll let you know what happens.

I've installed the new version as above and now it works great. Thank you for the quick response and solution!
