RQDA is an R package for computer assisted qualitative data analysis or CAQDAS. It is installable from, and runs within, the R system, but has a separate window running a graphical user interface (through RGtk2).

In the graphical interface it has the following functions:

• Import documents from plain text
• Support non-English documents, Simplified Chinese Character is well-tested under Windows
• Support character-level coding
• Memos for documents, codes, coding, project, files etc.
• Retrieve coding, and easily gets back to the original file. Conditional retrieval is supported as well.
• Single-file (*.rqda) format, which is basically the SQLite database
• Categorize codes (tree-like categories are avoided)
• Categorize files
• Search files by keywords and can highlight keyword in the open file
• Show attributes of files, which is useful for content analysis
• Categorise cases and related attributes of cases (to bridge qualitative and quantitative research)
• Search information about selected cases from the web
• Rename files, codes, code categories, cases etc.
• Write and organize fieldwork journals

Through use of R functions, it can:

• Import a batch of files
• Calculate the relation between two codings, given the coding indexes
• Give a summary of coding and inter-code relationship.
• Export file/case attributes and show subset of files/cases.
• Allow for more flexible conditional retrieval.
• Boolean operations of and, or and not.
