Description

Usage

generateTestData(n = 500, ...)

Arguments

n	number of observations for the test data (default: 500)
...	further named (artificial) variables to add to the data set

The further named parameters are either functions of the form FUN(n) which generates n values or a vector of values from which is sampled by sample(v, size=n, replace=TRUE). You may overwrite the internal functions (sex, ...) to generate your own values.

Value

a data frame

Examples

# create a single data set
d <- generateTestData(25)
str(d)
# create a single data set with an additional 'points' variable
d <- generateTestData(25, points=function(n) { sample(20, size=n, replace=TRUE)} )
str(d)
# generate panel data with two time points:
# 20 obs only in t1, 
# 10 in t1 and t2 and 
# 15 only in t2
n <- list(c(20, 1), c(10, 1, 2), c(15, 2))
d <- generateTestData(n)
str(d)
# generate panel data with three time points:
# 6 obs only in t1, 
# 5 in t1 and t2, 
# 8 in t1 and t3, 
# 7 in t1, t2 and t3
# 4 only in t2
# 3 in t2 and t3
# 2 only in t3
n <- list(c(6, 1), c(5, 1, 2), c(8, 1, 3), c(7, 1, 2, 3), c(4, 2), c(3, 2, 3), c(2, 3))
d <- generateTestData(n)
str(d)
