makePSData: Create a survey data set manually

Description

Create a survey data set from the command line rather than reading data in from a file. This function is likely to be only useful where there are a very small number of group sizes, or sizes of groups of glass.

Usage

makePSData(n, count = NULL, type = c("P", "S"), notes = NULL)
makeData(n, count = NULL, type = c("P", "S"), notes = NULL)
createPSData(n, count = NULL, type = c("P", "S"), notes = NULL)

Value

an object of type psData---see readData for more details.

Arguments

n

Either the number of groups of glass or the size of different groups of glass, or a vector of observed groups of glass, or group sizes. See details for a longer explanation.

count

Either the number of people in the survey sample who had \(n\) groups of glass on their clothing, or the number of people who had a group of glass of size \(n\).

type

either "P" or "S"

notes

a bibentry or a character string which allows extra information about the data to be stored, such as the source, or reference. NULL by default.

Details

If count is NULL, then it is assumed that n consists of actual observed group sizes or numbers of groups of glass found on a survey of N individuals. That is, one could provide n = rep(0:1, 98, 1) or n = 0:1, count = c(98, 1). The former is more useful when performing simulation studies.

Examples

## recreate the data read in the readData example
p1 = makePSData(n = c(0, 1, 2), count = c(98, 1, 1), type = "P")
s1 = makePSData(n = 1:3, count = c(1, 1, 1), type = "S")
