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.
Usage
checkVectorType(x, isType="numeric")
Value
no output is returned. If these tests fail, a stop condition
is executed.
Arguments
x
an S-PLUS object.
isType
a character string defining the class of the
object to be checked ala is(x,isType). Default: "numeric".
## expect no output from the following calls checkVectorType(rnorm(1024),"numeric")
checkVectorType(1:3,"integer")
checkVectorType(letters,"character")
