我正在尝试rJava在Win 7 64位的计算机上安装.我跑的时候
install.packages("rJava")
一切似乎都很好:
Installing package(s) into ‘C:/Users/djq/Documents/R/win-library/2.13’
(as ‘lib’ is unspecified)
trying URL 'http://software.rc.fas.harvard.edu/mirrors/R/bin/windows/contrib/2.13/rJava_0.9-1.zip'
Content type 'application/zip' length 654936 bytes (639 Kb)
opened URL
downloaded 639 Kb
package 'rJava' successfully unpacked and MD5 sums checked
The downloaded packages are in
C:\TEMP\RtmpW2eAUw\downloaded_packages
但是当我尝试加载库时,library(rJava)我收到以下错误:
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: inDL(x, as.logical(local), as.logical(now), ...)
error: unable to load shared object 'C:/Users/me/Documents/R/win-library/2.13/rJava/libs/x64/rJava.dll':
LoadLibrary failure: %1 is not a valid Win32 application.
Error: package/namespace …我安装了iplots和rjava包.当我这个库(iplots),我得到以下错误.我的电脑上安装了JDK.
Loading required package: rJava
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: fun(libname, pkgname)
error: JAVA_HOME cannot be determined from the Registry
错误:无法加载包'rJava'
我想将csv文件转换为excel。
从Internet上的搜索中，我发现最好的建议是使用库（xlsx）并使用write.xlsx（..）将数据框写入excel文件。
但是，当我尝试加载并使用xlsx库并使用它时，会收到以下消息：
Loading required package: rJava
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: inDL(x, as.logical(local), as.logical(now), ...)
error: unable to load shared object 'C:/Users/Ban/Documents/R/win-library/3.1/rJava/libs/x64/rJava.dll':
LoadLibrary failure: Could not find the specified mode. unit.
还有其他方法可以将csv转换为excel，还是有人遇到过以前的问题？
