I think I found the main problem! I am developing the package under Linux and after R CMD build, manually compressing the folder TinnRcom inside of the folder TinnRcom.RCheck and installing in Windows.
As the APPDATA environment variable does not exist in Linux, the function Sys.getenv ("APPDATA") is returning an empty string. I think the problem is it, now it is necessary to find a solution. Does anyone have a clue? -- ///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\ Jose Claudio Faria Estatistica UESC/DCET/Brasil joseclaudio.faria at gmail.com Telefones: 55(73)3680.5545 - UESC 55(73)9100.7351 - TIM 55(73)8817.6159 - OI ///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\ ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
