#GETTING RJAVA IN R INSTALL#

I didn't save the original error, but my experience on Linux was similar. onLoad failed in loadNamespace () for rJava, details: call: inDL (x, as.logical (local), as.logical. Install.packages( "rJava ", type = 'source ') # Success! The downloaded binary packages are in C:UsersabhishAppDataLocalTempRtmp0oCqXidownloadedpackages > library (RJDBC) Loading required package: rJava Error: package or namespace load failed for ‘rJava’. So now that I updated the compiler and runtime environment (JDK) and reconfigured R, I tried installing rJava from source, then installing RWeka.

Similarly, () suggested that the issue my colleague came across was due to mismatched compiler and runtime version (possibly with the runtime version being older than the compiler). A stackoverflow post (that I didn't save) suggested installing and compiling rJava from source, then installing your package. Then reconfiguring R from the command line: I first tried reinstalling the Java JDK with an up-to-date version: # error: JNI_GetCreatedJavaVMs returned -1 onLoad failed in loadNamespace() for 'RWekajars', details: We can install it with the classic: install. It also provides functionality to include our java resources into R packages easily. It allows creation of objects, calling methods and accessing fields of the objects. The rJava package provides a low-level interface to Java virtual machine. # JavaVM FATAL: Failed to load the jvm library. The rJava package an R to Java interface. # JavaVM: Failed to load JVM: /bundle/Libraries/libserver.dylib # JavaVM: requested Java version ((null)) not available. I have not been able to reproduce this exact error, but installing RWeka on both my Linux desktop (Mint 18) and my laptop (macOS 10.12.3) produced other errors. You'll probably end up hacking about to get it working. The document 'R, Java, rJava and macOS adventures' isn't complete and doesn't work off the cuff. ‘ / private / var / folders / l5 / jzzl6pp135b66b_rpb8tph_m0000gp / T / RtmpsIPZ5e / downloaded_packages’ Following the link provided in the comments below, I managed to get the latest version of Java JDK running through rJava in RStudio.

By using that, I basically skip the installation steps that rJava performs for R CMD INSTALL. Installing package into ‘ / Users / / Library / R / 3.3 / library’ R Workbench or RStudio:This is the GUI used to run R scripts.
