Caros,

executei a instalação do Rmysql no ubuntu sem sucesso. já executei o primeiro passo das instruções mas nao sei como fazer o segundo passo... alguma sugestão?

Configuration error:
  could not find the MySQL installation include and/or library
  directories.  Manually specify the location of the MySQL
  libraries and the header files and re-run R CMD INSTALL.

INSTRUCTIONS:

1. Define and export the 2 shell variables PKG_CPPFLAGS and
   PKG_LIBS to include the directory for header files (*.h)
   and libraries, for example (using Bourne shell syntax):

      export PKG_CPPFLAGS="-I<MySQL-include-dir>"
      export PKG_LIBS="-L<MySQL-lib-dir> -lmysqlclient"

   Re-run the R INSTALL command:

      R CMD INSTALL RMySQL_<version>.tar.gz

2. Alternatively, you may pass the configure arguments
      --with-mysql-dir=<base-dir> (distribution directory)
   or
      --with-mysql-inc=<base-inc> (where MySQL header files reside)
      --with-mysql-lib=<base-lib> (where MySQL libraries reside)
   in the call to R INSTALL --configure-args='...' 

   R CMD INSTALL --configure-args='--with-mysql-dir=DIR' RMySQL_<version>.tar.gz
