I am currently conducting a large-scale event study. I am using R and the EventStudy package. It turns out that I am only able to upload around 2000 stock prices otherwise I receive the error code:
Request Status Code: 500
Error: Argument 'txt' must be a JSON string, URL or file
Is there any way to use the package for a large amount of data e.g. 200k stock prices in the overall analysis?
Dear Dr. Schimmer,
when I try to use the API, I receive the following error message. This happens even when I use the sample data from the package:
Loading required package: shiny
Listening on http://127.0.0.1:5750
 "Validate input files."
 "Perform Event Study"
 "Check batch process: Step 0"
Warning: Error in UseMethod: no applicable method for 'http_error' applied
to an object of class "data.frame"
Until Wednesday it worked fine. Now not anymore. May you tell me whats the reason for it and how to solve it? I despaire of it!
