rjava操作说明及注意事项（Rjava operating instructions and precautions）

rjava操作说明及注意事项（Rjava operating instructions and precautions） R is a powerful tool for statistical computing, and JAVA is the mainstream language for application systems, both of which naturally have the need to integrate. JAVA is good for developing application systems, but mathematical modeling and computing capabilities are not good. If the system needs to do a lot of statistical or optimized calculations, calling R is a good way. JAVA is responsible for the construction of the system, and R is used as the computing engine to realize the combination of application and analysis. RJava is a R language and Java language communication interface, through the underlying JNI implementation call, allowing direct calls to objects and methods of Java in R. RJava also provides the ability to call R from Java, which is implemented through JRI (Java/R Interface). JRI has now been embedded into the rJava package, and we can also experiment with this functionality individually. There are two ways to call R through Java; one is Rserve, and the other is rJava. The rJava approach takes advantage of the functions in R by invoking the dynamic link library of R. Chapter introduction: 1. environment Installation of 2.rJava 3.rJava implements R call Java 4.rJava implements Java call R 1. environment: Win7+RStudio+Eclipse Installation of 2.rJava install.packages (rJava) After installation, you need to modify the environment variables, add%R_HOME%/bin and%R_HOME%/library/rJava/jri in PATH, and pay attention to the correct path of R_HOME, restart the system and make it effective. My R_HOME path is: D:\R-3.1.1 The section about rJava in PATH is: %R_HOME%\bin;%R_HOME%\library\rJava\jri;%R_HOME%\library\rJava\jri\i386; 3.rJava implements R call Java Library (rJava) Warning message: The program package rJava was built with the R version 3.1.2 Search () [1] .GlobalEnv, package:rJava, tools:rstudio [4] package:stats, package:graphics, package:grDevices [7] package:utils, package:datasets, pac
