The Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute (NCI) is an authoritative source of information on cancer incidence and survival in the United States. The SEER*Stat software developed by NCI provides a convenient, intuitive mechanism for the analysis of SEER and other cancer-related databases. SEER*STAT presents results in matrix session and users can export results into data file (either in plain text format or gz format) and dictionary information into dic file. read.SeerStat reads data and dictionary information from SEER*STAT export files. write.SeerStat writes data and dictionary information to files in the formats of SEER*STAT export files
