I tried to use  "R CMD BiocCheck" to check a package I am working on.

I got the following notes from checking:

I just want to know  if there is an easy way to format my codes. 

Or I have to format all codes line by line. 

* CONSIDER: Shortening lines; 214 lines (11%) are > 80 characters

      long.

* CONSIDER: Replacing tabs with 4 spaces; 3 lines (0%) contain

      tabs.

* CONSIDER: Indenting lines with a multiple of 4 spaces; 507 lines

      (26%) are not.

Hi, 

There are several ways you can check and format your code as suggested in BiocCheck.

These include:

goodpractice::gp (checker function - MangoTheCat/goodpractice github repository)

lintr (checker package)

formatR (text formatting package)

RStudio settings (best used when writing)

You can also ask this question about package development in the bioc-devel mailing list for more input. 

Best regards,

Marcel
