Generate example data tables as presented in "Accelerated Testing" by Wayne Nelson

Description

This function generates life test data tables suitable for use in example scripts.

Usage

	NelsonData(x)

Arguments

x	Either a character string defining one of "table2.2", "table3.1", "table4.1" or "table5.1 or a numeric of the table digits.

Details

This method of data provision has been found necessary since inclusion of table3.1 and table5.1 created a problem with a "Warning: object '.Random.seed' is created by more than one data call" which prevented lazyData=yes to be in the package definition. Without lazyData I could never seem to make data files avialable to example scripts within the package.

Table 2.1 is presented on page115 of Wayne Nelson's book "Accelerated Testing". It purports to represent a series tests on a Class H insulation at elevated temperatures (in deg C)

Table 3.1 is presented on page129 of Wayne Nelson's book "Accelerated Testing". It purports to represent a series tests on an insulating fluid at elevated voltages.

Table 4.1 is presented on page135 of Wayne Nelson's book "Accelerated Testing". It purports to represent a series tests on a Class B insulation at elevated temperatures (in deg C)

Table 5.1 is presented on page 393 of Wayne Nelson's book "Accelerated Testing". It is interesting to note that items $T190, $T220, $T240, and $T260 represent a Table 5.1 presented on page 140. In Chapter 7 this data forms an example of competing modes analysis covering modes of failure on motorette turns, phase, and ground.

Value

The returned object is either a dataframe or a list that can be accessed by the names of the olumns or elments.
