test.psych {psych}R Documentation

Testing of functions in the psych package

Description

Test to make sure the psych functions run on basic test data sets

Usage

test.psych(first=1,last=5,short=TRUE)

Arguments

first first=1: start with dataset first
last last=5: test for datasets until last
short short=TRUE - don't return any analyses

Details

When modifying the psych package, it is useful to make sure that adding some code does not break something else. The test.psych function tests the major functions on various standard data sets. It also shows off a number of the capabilities of the psych package.

Uses 5 standard data sets:
USArrests Violent Crime Rates by US State (4 variables)
attitude The Chatterjee-Price Attitude Data
Harman23.cor$cov Harman Example 2.3 8 physical measurements
Harman74.cor$cov Harman Example 7.4 24 mental measurements
ability.cov$cov 8 Ability and Intelligence Tests

Value

out if short=FALSE, then list of the output from all functions tested

Warning

Warning messages will be thrown by fa.parallel and sometimes by factor.pa for random datasets.

Note

Although test.psych may be used as a quick demo of the various functions in the psych packge, in general, it is better to try the specific functions themselves. The main purpose of test.psych is to make sure functions throw error messages or correct for weird conditions.

The datasets tested are part of the standard R data sets and represent some of the basic problems encountered.
