O manual do R
diz o seguinte:




Note that this unfortunately depends on the exact version of the JRE/JDK
installed, and so may need updating if the Java installation is updated.
This can be done by running R CMD javareconf which updates settings in both
etc/Makeconf and R_HOME/etc/ldpaths. See R CMD javareconf --help for




Contudo, ao executar tal comando no Windows, recebo a seguinte msg:



C:\Program Files\R\R-3.2.0\bin>R CMD javareconf

'javareconf' não é reconhecido como um comando interno

ou externo, um programa operável ou um arquivo em lotes.



Ao executar o Help do comando, deparo com o seguinte:




C:\Program Files\R\R-3.2.0\bin>R --arch x64 --help

Usage: Rterm [options] [< infile] [> outfile] [EnvVars]


Start R, a system for statistical computation and graphics, with the

specified options


EnvVars: Environmental variables can be set by NAME=value strings



  -h, --help            Print usage message and exit

  --version             Print version info and exit

  --encoding=enc        Specify encoding to be used for stdin

  --encoding enc        ditto

  --save                Do save workspace at the end of the session

  --no-save             Don't save it

  --no-environ          Don't read the site and user environment files

  --no-site-file        Don't read the site-wide Rprofile

  --no-init-file        Don't read the .Rprofile or ~/.Rprofile files

  --restore             Do restore previously saved objects at startup

  --no-restore-data     Don't restore previously saved objects

  --no-restore-history  Don't restore the R history file

  --no-restore          Don't restore anything

  --vanilla             Combine --no-save, --no-restore, --no-site-file,

                          --no-init-file and --no-environ

  --max-mem-size=N      Set limit for memory to be used by R

  --max-ppsize=N        Set max size of protect stack to N

  -q, --quiet           Don't print startup message

  --silent              Same as --quiet

  --slave               Make R run as quietly as possible

  --verbose             Print more information about progress

  --internet2           Use Internet Explorer settings for proxies etc.

  --args                Skip the rest of the command line

  --ess                 Don't use getline for command-line editing

                          and assert interactive use

  -f file               Take input from 'file'

  --file=file           ditto

  -e expression         Use 'expression' as input


One or more -e options can be used, but not together with -f or --file


An argument ending in .RData (in any case) is taken as the path

to the workspace to be restored (and implies --restore)




Or: R CMD command args


where 'command' is one of:

  INSTALL  Install add-on packages

  REMOVE   Remove add-on packages

  SHLIB    Make a DLL for use with dynload

  BATCH    Run R in batch mode

  build    Build add-on packages

  check    Check add-on packages

  Rprof    Post process R profiling files

  Rdconv   Convert Rd format to various other formats

  Rdiff    difference R output files

  Rd2pdf   Convert Rd format to PDF

  Rd2txt   Convert Rd format to pretty text

  Stangle   Extract S/R code from vignette

  Sweave    Process vignette documentation

  config   Obtain configuration information about R

  open     Open a file via Windows file associations

  texify   Process a latex file



  R CMD command --help

for usage information for each command.




A questão é a seguinte:

Foi abandonado o suporte R ao java na versão 3.2, visto que tal comando
agora não existe?
