R: Boolean Equality Testing Function

omxCheckTrue {OpenMx} | R Documentation

## Boolean Equality Testing Function

### Description

This function tests whether an object is equal to TRUE.

### Usage

    omxCheckTrue(a)

### Arguments

`a` | the value to test.

### Details

Checks element-wise whether an object is equal to TRUE. If any of the elements are false, then an error will be thrown. If ‘a’ is TRUE, by default the function will print a statement informing the user the test has passed. To turn off these print statements use `options("mxPrintUnitTests" = FALSE)`.
