The EdSurvey package uses appropriate methods for analysis of the NCES data sets with a small memory footprint. Existing system control files, included with the data, are used to read in and format the data for further processing.
To get started using EdSurvey, see the vignettes covering
installation, first use, use of the
getData function to get data than can be further manipulated
or analyzed, and use of the accommodations datasets. Use
browseVignettes(package="EdSurvey") to see the vignettes.
The package provides a function called readNAEP
to read in NAEP data.
The functions lm.sdf, cor.sdf,
edsurveyTable, and achievementLevels
can then be used to analyze data while getData extracts
the data of interest as a data.frame for further processing.
