This Communication contains the Project Report, which describes the Internet-Based Health and Air Pollution Surveillance System (iHAPSS), along with Comments from some members of the HEI Health Research and Review Committees and other experts who had used the data.

The Johns Hopkins Biostatistics Center offers comprehensive data management and biostatistical services, consulting for Bloomberg School students, and consulting for researchers inside and outside the Johns Hopkins community.

Interested readers are also en-couraged to visit the Internet-based Health and Air Pollution Surveillance System (IHAPSS) website at http://www.ihapss.jhsph.edu/ which contains more details about how the data were originally pro-cessed. The NMMAPSdata package can be loaded into R in the usual way.

The NMMAPSdata package can be downloaded from http://www.ihapss.jhsph.edu/data/NMMAPS/R/. The package does not currently reside on CRAN, although it passes all R CMD check quality control tests. A source package as well as a Windows binary package are available for download.

2004年7月21日 · NMMAPSdata is an R package which contains time series data on air pollution, weather, and mortality for 108 United States cities for the years 1987--2000. These data were originally assembled for the National Morbidity, Mortality, and Air Pollution Study sponsored by the Health Effects Institute and have since been updated.
