Hi,

I am trying to Knit my Rmarkdown file in R Studio, but get this message:

Quitting from lines 12-55 (MBV-INFX410-transcriptomics.Rmd)
Error in eval(expr, envir, enclos) :
  could not find function "Biocexptpkg"
Calls: <Anonymous> ... in_dir -> inline_exec -> withVisible -> eval -> eval
Execution halted

Line 12 only contains this ## Experimental

Thanks, Jon

You need to load the BiocStyle package if you want to call functions from that package, which includes using that set of styles for your rmarkdown file.

Hard to tell what's going on, not enough info here, but:

I'm pretty sure that Rmd errors usually give the range of the chunk that threw the error, so the code is in lines 12-55 (not just line 12)

Run the chunks of your Rmd file one by one until you get to the code block that is giving the error. Step through that line by line and debug from there.

If you are in RStudio, this process is made easy with its "run all chunks above" and other run functions available from the toolbar in the editor.

Thanks a lot! Problem solved! :)
