RDQA is a R package for Qualitative Data Analysis, a free qualitative analysis software application (BSD license). It works on Windows, Linux/FreeBSD and Mac OSX platforms. RQDA is an easy to use tool to assist in the analysis of textual data.
At the moment it only supports plain text formatted data. All the information is stored in a SQLite database via the R package of RSQLite. The GUI is based on RGtk2, via the aid of gWidgetsRGtk2.
It includes a number of standard Computer-Aided Qualitative Data Analysis features. In addition it seamlessly integrates with R, which means that a) statistical analysis on the coding is possible, and b) functions for data manipulation and analysis can be easily extended by writing R functions.
To some extent, RQDA and R make an integrated platform for both quantitative and qualitative data analysis.
When RDQA is launched, it is better to minimize the main window of R (e.g. Rgui, Rterm, terminal from which R is launched). RQDA 0.2-8 is released on CRAN (2016-12-12). The most important changes include profile matrix (Kuckartz, 2014) and Portuguese translation, among others.
Unfortunately, this release is not compatible with RSQLite 1.1.0, which means that users need to downgrade RSQLite to 1.0.0 to make RQDA works properly. This problem will be fixed in development version on GitHub. The technical aspect is that RQDA needs to convert ' into '' using gsub in order to save it in the SQLite database, without proper locales, the conversion may not give users what users want.
