Olá, O manual do R (http://cran.r-project.org/doc/manuals/r-release/R-admin.html#Java-support) diz o seguinte: <PRINT> 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 details. </PRINT> Contudo, ao executar tal comando no Windows, recebo a seguinte msg: <PRINT> 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. </PRINT> Ao executar o Help do comando, deparo com o seguinte: <PRINT> 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 Options: -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 Use R CMD command --help for usage information for each command. </PRINT> A questão é a seguinte: Foi abandonado o suporte R ao java na versão 3.2, visto que tal comando agora não existe?
