I am trying to publish a shiny app, but getting the following error. My code is working fine in Rstudio though. Only get this error when I try to publish it.

       install.packages("BiocManager")

 
     BiocManager::install("Rgraphviz")

Error: Unhandled Exception: Child Task 1195199124 failed: Error parsing manifest: Unable to determine package source for Bioconductor package BiocGenerics: Repository must be specified Execution halted

How can I solve this problem? How to specify a repository? TIA

CodePudding user response：

Before publishing your app, run options(repos = BiocManager::repositories()) on your console. Do NOT copy this code to your app scripts. Then, publish your app. No need of install.packages("BiocManager") or BiocManager::install("Rgraphviz")
