omxCheckWithinPercentError {OpenMx} | R Documentation |

This function tests whether two numeric vectors or matrixes are approximately equal to one another, within a specified percentage.

omxCheckWithinPercentError(a, b, percent = 0.1)

`a` |
A numeric vector or matrix. |

`b` |
A numeric vector or matrix. |

`percent` |
A non-negative percentage. |

Arguments ‘a’ and ‘b’ must be of the same type, ie. they must be either vectors of equal dimension or matrices of equal dimension. The two arguments are compared element-wise for approximate equality. If the absolute value of the difference of any two values is greater than the percentage difference of ‘a’, then an error will be thrown. If ‘a’ and ‘b’ are approximately equal to each other, 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)`
