lexisDS2

Description

The second serverside function called by ds.lexis.

Usage

lexisDS2(datatext = NULL, intervalWidth, maxmaxtime, idCol, entryCol,
  exitCol, statusCol, vartext = NULL)

Arguments

datatext

a clientside provided character string specifying the data.frame holding the data set to be expanded

intervalWidth

a clientside generated character string specifying the width of the survival epochs in the expanded data

maxmaxtime

a clientside generated object specifying the maximum follow up time in any of the sources

idCol

a clientside generated character string specifying the variable holding the IDs of indivuals in the data set to be expanded

entryCol

a clientside specified character string identifying the variable holding the time that each individual starts follow up

exitCol

a clientside specified character string identifying the variable holding the time that each individual ends follow up (is censored or fails)

statusCol

a clientside specified character string identifying the variable holding the final censoring status (failed/censored)

vartext

is a clientside provided vector of character strings denoting the column names of additional variables to include in the final expanded table. If the 'variables' argument is not set (is null) but the 'data' argument is set the full data.frame will be expanded and carried forward

Details

This is the assign function which actually creates the expanded dataframe containing surival data for a piecewise exponential regression. lexisDS2 also carries out a series of disclosure checks and if the arguments or data fail any of those tests, creation of the exapanded dataframe is blocked and an appropriate serverside error message is stored. For more details see the extensive header for ds.lexis.
