This is from your .Rbuildignore file.

`\` is usually interpreted as an escape character, e.g., to interpret '.' as a literal period rather than a wild-card one would write `\.`. I think you're trying to use it as a file path delimiter, and the easiest solution is to adopt the Linux convention `/ignore`.

(but there is no 'ignore' folder in your git repository, so maybe you can just delete the line from .Rbuildignore?)

The change is likely because R has changed, in the 4.0 release branch, the underlying 'perl-compatible regular expression' (PCRE) library it uses for regular expression matching.

    Hello,
    
    My package HPAanalyze (https://doi.org/doi:10.18129/B9.bioc.HPAanalyze) has
    been having problem with the devel build/check, and I am not sure how to
    troubleshoot it. The release branch has the same content, but does not have
    this issue. The error note for all platforms are the same below:
    
    * checking for file ‘HPAanalyze/DESCRIPTION’ ... OK
    * preparing ‘HPAanalyze’:
    * checking DESCRIPTION meta-information ... OK
    Warning in grepl(e, files, perl = TRUE, ignore.case = TRUE) :
      PCRE pattern compilation error
    	'unrecognized character follows \'
    	at 'ignore'
    Error in grepl(e, files, perl = TRUE, ignore.case = TRUE) :
      invalid regular expression '^\ignore'
    Execution halted
    
    I looked at the "ignore" folder, but it doesn't seem to contain any special
    characters. This branch was pushed a few month ago, but only started having
    this problem recently.
    
    May you help me to figure out what's wrong, please?
    
    Thank you very much.
    Sincerely,
    Anh Tran.
