Cannot install qdap on RStudio

[vivvi87]

Hi ! I am trying to install the package but running into the following message when I load it:

 install.packages("qdap")
trying URL 'https://cran.rstudio.com/bin/macosx/el-capitan/contrib/3.6/qdap_2.4.3.tgz'
Content type 'application/x-gzip' length 3619579 bytes (3.5 MB)

No Java runtime present, try --request to install.
Error: package or namespace load failed for ‘qdap’:

  call: fun(libname, pkgname)
  error: JVM could not be found
In addition: Warning messages:
1: package ‘qdap’ was built under R version 3.6.2 
2: In system("/usr/libexec/java_home", intern = TRUE) :
  running command '/usr/libexec/java_home' had status 1
3: In fun(libname, pkgname) :
  Cannot find JVM library 'NA/lib/server/libjvm.dylib'
Install Java and/or check JAVA_HOME (if in doubt, do NOT set it, it will be detected)

I have found some possible solutions online but no one of them seems to work (also it seems like none of the person who had a similar problem had the same error message as I get). Any suggestion? Thanks !

You may encounter this error when R is cannot find JAVA _HOME on your system. You can download Oracle Java installation guide here. Once the installation is done, you may need to restart RStudio to install the package.
