I'm using R 4.5.2 with RStudio 2026.01.0 Build 392 under Windows 11 using Defender for protection. In spite of giving R and Rstudio access to all controlled folders, I find debugging impossible.
If I source a file after setting a breakpoint and then try and explore data in the console when execution stops at the breakpoint, RStudio takes my input, appears to execute it if it has no errors, but doesn't print anything! I can view data using View(), but not in any other way. Has anyone experienced this problem, and if so, how can I work interactively with R in RStudio?
Sincerely
Thomas Philips
