WinZip 14 provides support for Windows 7 libraries. Libraries group together folders with a common theme regardless of where the folders reside. For instance, the Windows 7 Pictures library groups all your separate folders that contain pictures in one convenient place. WinZip allows you to create and open Zip files in these. All Libraries (Zip All Libraries): this job zips all of the files and folders contained in all of the user's Libraries, including any custom Libraries that the user may have created. The resulting Zip file is called 'Libraries.zipx'. This pre-configured job is only available in Windows 7 or later. Documents Library (Zip Documents.
I'm trying to install rJava on a computer with Win 7 64 bit. (Note: many of folks in other answers/comments have said to remove JAVA_HOME, so consider that. I have not revisited this issue recently to know if all the steps below are still necessary.) Here is some quick advice on how to get up and running with R + rJava on Windows 7 64bit.
There are several possibilities, but most have fatal flaws. Here is what worked for me: Add jvm.dll to your PATH rJava, the RJava bridge, will need jvm.dll, but R will have trouble finding that DLL. It resides in a folder like C: Program Files Java jdk1.6.0_25 jre bin server or C: Program Files Java jre6 jre bin client Wherever yours is, add that directory to your windows PATH variable.
(Windows -> 'Path' -> 'Edit environment variables to for your account' -> PATH -> edit the value.) You may already have Java on your PATH. If so you should find the client/server directory in the same Java 'home' dir as the one already on your PATH. To be safe, make sure your architectures match.If you have Java in Program Files, it is 64-bit, so you ought to run R64. If you have Java in Program Files (x86), that's 32-bit, so you use plain 32-bit R. Re-launch R from the Windows Menu If R is running, quit.
From the Start Menu, Start R / RGUI, RStudio. This is very important, to make R pick up your PATH changes. Install rJava 0.9.2. Earlier versions do not work!
FileHippo App Manager will scan your computer for installed applications, check the versions and then send this data to FileHippo.com to ascertain if there are any newer releases available. From FileHippo App Manager is a great application that will keep your system up-to-date. Filehippo download.
Mirrors are not up-to-date, so go to the source at www.rforge.net:. Note the advice there “Please use `install.packages('rJava',,'to install.” That is almost correct. This actually works: install.packages('rJava',.libPaths()[1], 'Watch the punctuation! The mysterious “.libPaths()[1],” just tells R to install the package in the primary library directory. For some reason, leaving the value blank doesn’t work, even though it should default. Getting rJava to work depends heavily on your computers configuration: • You have to use the same 32bit or 64bit version for both: R and JDK/JRE. A mixture of this will never work (at least for me).
