In ifultools: Insightful Research Tools

Description Usage Arguments Value See Also Examples

Tests the input for being a vector (as defined by the isVectorAtomic function and checks the class of the vector. This function is meant to be used internally for function input argument verification and typically will not be used otherwise.

1	checkVectorType(x, isType="numeric")

`x`	an S-PLUS object.
`isType`	a character string defining the class of the object to be checked ala `is(x,isType)`. Default: `"numeric"`.

no output is returned. If these tests fail, a stop condition is executed.

isVectorAtomic, checkScalarType, checkRange.

## expect no output from the following calls 
checkVectorType(rnorm(1024),"numeric")
checkVectorType(1:3,"integer")
checkVectorType(letters,"character")
