I have developed my own R library (called HAM)

When I use the install() command from the library roxygen2, the result looks as shown below:

* installing *source* package 'HAM' ...
** R
** preparing package for lazy loading

What is the problem? All relevant libraries are installed on my PC, so there should not be an error message claiming that a dependent library is missing.

  • You need to show us the `DESCRIPTION` and `NAMESPACE` files. Apparently one of your dependencies needs to launch a Java VM, and is unable to do so. Do you have Java SDK installed on your computer? – tchakravarty Jan 26 '15 at 09:25
  • Description file looks as follows Description: The library collects all user-defined functions of Hinder Asset Management. It is work in progress and will expand continuously. Depends: R (>= 3.1.1), PerformanceAnalytics, xts, zoo, lmtest, car, sandwich, strucchange, tseries, urca, gmm, png, grid, Rbbg, openxlsx, xlsx, calibrate, reshape, lubridate, fAssets, fPortfolio, BurStFin, quantmod, tawny License: GPL 3 LazyData: true I do have JRE Version 8, Update 25 installed. – user2157086 Jan 26 '15 at 10:08
  • Please add this to the original post. Based on a quick look through the dependencies, `xlsx` would be a problem. Please add `sessionInfo()` output to your question, and also whether you are able to install and load all the dependencies on your system, outside of the package installation. – tchakravarty Jan 26 '15 at 10:12
  • Thx for help. I was able to track down the problem: one cannot have the two libraries {openxlsx} and {xlsx} being used/loaded in the same library since they interfere with each other. – user2157086 Jan 27 '15 at 08:34
