addDataDensity: Add data from a density defined by a vector of integers

In simstudy: Simulation of Study Data

Add data from a density defined by a vector of integers

Description

Data are generated from an a density defined by a vector of integers.

Usage

addDataDensity(dtOld, dataDist, varname, uselimits = FALSE, na.rm = TRUE)

Arguments

dtOld	Name of data table that is to be updated.
dataDist	Numeric vector. Defines the desired density.
varname	Character. Name of the variable.
uselimits	Logical. If TRUE, the minimum and maximum of the input data vector are used as limits for sampling. Defaults to FALSE, in which case a smoothed density that extends beyond these limits is used.
na.rm	Logical. If TRUE (default), missing values in 'dataDist' are removed. If FALSE, the data will retain the same proportion of missing values.

Value

A data table with the generated data.

Examples

def <- defData(varname = "x1", formula = 5, dist = "poisson")

data_dist <- data_dist <- c(1, 2, 2, 3, 4, 4, 4, 5, 6, 6, 7, 7, 7, 8, 9, 10, 10)

dd <- genData(500, def)
dd <- addDataDensity(dd, data_dist, varname = "x2")
dd <- addDataDensity(dd, data_dist, varname = "x3", uselimits = TRUE)
