RDQA is a package for Qualitative Data Analysis.It includes a number of standard Computer-Aided Qualitative Data Analysis features.

By the GUI, it can:
# Import documents from plain text
# Support non-English documents, Simplified Chinese Character is well-tested under Windows
# Character-level coding using codes
# Memos of documents and codes
# Retrieval of coding
# Single-file (*.rqda) format, which is basically SQLite database
# Temporary deletion of files and codes

By R functions, it can:
# Show the temporary deletion files and codes
# Undo the temporary deletion
# Permanently erase the temporary deletion

There are lots of works ahead, but the current version is workable for basic QDA.
