R尝试加载qdap包时出错

Question

所以我正在尝试运行

library(ggplot2)
library(qdap)

但是这个错误不断出现：

Unable to find any JVMs matching version "(null)".
No Java runtime present, try --request to install.
Error: package or namespace load failed for ‘qdap’:
 .onLoad failed in loadNamespace() for 'rJava', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so':
  dlopen(/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so, 6): Library not loaded: @rpath/libjvm.dylib
  Referenced from: /Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so
  Reason: image not found
In addition: Warning message:
running command '/usr/libexec/java_home' had status 1 

我在mac上使用Rstudio中的R，我已经解决了很多类似的问题，但似乎都不起作用。我对R的使用还很陌生，如果有任何帮助，我将不胜感激。

我试着用

install.packages("openNLPdata")

我认为这是一件好事

trying URL 'https://cran.rstudio.com/bin/macosx/el-capitan/contrib/3.4/openNLPdata_1.5.3-4.tgz'
Content type 'application/x-gzip' length 7323402 bytes (7.0 MB)
==================================================
downloaded 7.0 MB


    The downloaded binary packages are in
        /var/folders/h5/_5bjqp9j0g5gqr1794sw1xwh0000gn/T//RtmpaknsV6/downloaded_packages

但是错误仍然会发生。

提前感谢

似乎该包可能需要rJava才能运行，而您的环境中可能没有加载该包。尝试：

install.packages('rJava')
library('rJava')
