R尝试加载qdap包时出错

Question

So I am trying to run the

library(ggplot2)
library(qdap)

but this error keeps coming up:

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:

I am using R in Rstudio on a mac, and I've trawled through quite a few similar questions but none seem to work. I am quite new to using R and any help would be great thanks.

I tried using

install.packages("openNLPdata")

and this showed up which I think is a good thing

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

But the error still occurs.

Thanks in advance

It seems like that package might need rJava to run, which may not be loaded in your environment. Try:

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