[R-pkg-devel] Package update submission to CRAN fails on pretest

[Wolfgang Lenhard]

Dear list,
I am getting problems when trying to submit an update of the package 
cNORM to CRAN. I am developing the package with RStudio and devtools and 
I am using Travis for automatic testing. The package is tested locally 
on Win10 and Mac OS X and on Travis with Ubuntu and Mac both for 
development and release versions of R. All local tests and tests on 
Travis work flawlessly - no errors, warning or notes. When submitting to 
CRAN, a note and an error show up on some of the Linux OS (Fedora & 
Solaris) and Mac OS X, while others display an 'OK' (Win, Debian). The 
results: https://cran.r-project.org/web/checks/check_results_cNORM.html

- error: This seems to be related to the vignette with the following 
message:
> * checking examples ... ERROR
> Running examples in ‘cNORM-Ex.R’ failed
I can however not identify the location of the error

- Note: Check: data for non-ASCII characters

The strange thing is: I checked all data files multiple times. They 
mainly consist of data.frames with numerics and all colnames  are ASCII. 
I am not able to replicate the issue. The same is true for the error, 
which does not show up on Travis and as well locally. And finally, the 
results state, that the version of the package is 1.0.1, which had been 
the first submission to CRAN a month ago. The current version of the 
package is 1.1.1. Could this be the reason for the problem?

Do you have an idea how to progress with the testing or how to locate 
the errors? Any help is welcome.

Best regards,
     Wolfgang Lenhard
