Troubleshooting RJSONIO Installation on R 3.0.2 and Debian Wheezy 7.3

Introduction

R, the popular statistical programming language, has a vast ecosystem of packages that can be installed using the install.packages() function. One such package is RJSONIO, which provides an interface to read and write JSON data in R. In this article, we will delve into the issues faced by a new R user while installing RJSONIO on R 3.0.2 and Debian Wheezy 7.3.

Background

RJSONIO is a package that allows users to easily work with JSON data in R. It provides an interface to read and write JSON files, as well as perform common operations such as parsing and generating JSON data. The package is available for various platforms, including Windows, macOS, and Linux.

Debian Wheezy 7.3 and R 3.0.2

In this article, we will focus on troubleshooting the installation of RJSONIO on Debian Wheezy 7.3 with R 3.0.2. The target system uses an older version of gcc, which might lead to compatibility issues.

Installation Steps

The user has successfully installed R and RStudio using the official R installation guide. They have then tried to install packages needed for RHadoop, including RJSONIO, using the following commands:

R CMD INSTALL Rcpp_0.10.6.tar.gz
R CMD INSTALL stringr_0.6.2.tar.gz
R CMD INSTALL plyr_1.8.tar.gz
R CMD INSTALL functional_0.4.tar.gz
R CMD INSTALL digest_0.6.4.tar.gz

However, the user encountered issues while installing RJSONIO using the following command:

R CMD check RJSONIO_1.0-3.tar.gz

The error message produced is as follows:

rlibjson.c: In function 'R_json_stream_parse':
rlibjson.c:449:5: warning: passing argument 1 of 'json_new_stream' from incompatible pointer type [enabled by default]
In file included from Rlibjson.h:1:0,
                 from rlibjson.c:1:
./libjson/libjson.h:68:18: note: expected 'json_stream_callback_t' but argument is of type 'void (*)(void *)'
rlibjson.c:449:5: error: too few arguments to function 'json_new_stream'

The warning and error messages indicate a compatibility issue between the RJSONIO package and the gcc version used on the target system.

Solution

To resolve this issue, we need to install the RJSONIO package using a different repository. The recommended solution is to use the Omega Hat repository, which provides the latest versions of R packages, including RJSONIO.

Here’s how you can do it:

install.packages("RJSONIO", repos = "http://www.omegahat.org/R", type="source")

This command will download and install the RJSONIO package from the Omega Hat repository, which is compatible with R 3.0.2 on Debian Wheezy 7.3.

Conclusion

In this article, we discussed the issues faced by a new R user while installing RJSONIO on R 3.0.2 and Debian Wheezy 7.3. We examined the installation steps and error messages to identify the compatibility issue between the RJSONIO package and the gcc version used on the target system.

By using the Omega Hat repository, we were able to resolve the issue and successfully install the RJSONIO package. This highlights the importance of regularly updating your packages to ensure compatibility with the latest versions of R.

Troubleshooting Tips

• Ensure that you are using the correct version of gcc for your target system.
• Regularly update your packages to ensure compatibility with the latest versions of R.
• Use a different repository, such as the Omega Hat repository, when installing packages that are incompatible with the default repositories.
