将 qdap package 安装到 R 时出现问题

Question

I want to install "qdap" package to run a text mining project. I tried installing the package in many different ways: 1. intsall.packages("qdap") 2. Downloading the file locally then installing 3. Using devtools

library(devtools)
install_github("trinker/qdapDictionaries")
install_github("trinker/qdapRegex")
install_github("trinker/qdapTools")
install_github("trinker/qdap")

I always had the same problem. It seems to be related to rJava package. I tried to install rJava but I wasn't successful.

I'm more of a data analyst than a developer so I don't have much experience with development (using terminal commands or fixing java on my mac).

I'd really like to use this "qdap" package. Could you please help me figure out in a simple manner?

Here's the error message after I install the package:

Answer 1

Maybe the key is in the following

Unable to find any JVMs matching version "(null)".
No Java runtime present, try --request to install.

and

Warning in system("/usr/libexec/java_home", intern = TRUE) :
  running command '/usr/libexec/java_home' had status 1

Are you sure you have installed a JVM? And if yes, the correct one? Because it seems to not find it.

You can download JVM from here .

I hope this helps!
