Distributed Data Structures in R (ddR)
Provides distributed data structures and simplifies distributed computing in R.
Jackknife Estimates of Kaplan-Meier Estimators or Integrals (jackknifeKME)
Computing the original and modified jackknife estimates of Kaplan-Meier estimators.
Imputing the Last Largest Censored Observation(s) Under Weighted Least Squares (imputeYn)
Method brings less bias and more efficient estimates for AFT models.
Simulated Survival and Hazard Analysis for Time-Dependent Exposure (SimHaz)
Generate power for the Cox proportional hazards model by simulating survival events data with time dependent exposure status for subjects. A dichotomous exposure variable is considered with a single transition from unexposed to exposed status during the subject’s time on study.
Automated Schema on Read (SchemaOnRead)
Provides schema-on-read tools including a single function call (e.g., schemaOnRead(‘filename’)) that reads text (‘TXT’), comma separated value (‘CSV’), raster image (‘BMP’, ‘PNG’, ‘GIF’, ‘TIFF’, and ‘JPG’), R data (‘RDS’), HDF5, NetCDF, spreadsheet (‘XLS’, ‘XLSX’, ‘ODS’, and ‘DIF’), Weka Attribute-Relation File Format (‘ARFF’), Epi Info (‘REC’), SPSS (‘SAV’), Systat (‘SYS’), and Stata (‘DTA’) files. It also recursively reads folders (e.g., schemaOnRead(‘folder’)), returning a nested list of the contained elements.
