Re: how to check for NumericQ arbitrary data structure


data1 = {2, {Pi, 0.5}, {1/2, {I, 3 Sin[2]}, {6}}};
data2 = {a, {Pi, 0.5}, {1/2, {I, 3 Sin[2]}, {6}}}; 

VectorQ[Flatten[data1], NumericQ]
VectorQ[Flatten[data2], NumericQ] 
True
False

Hi,
I have a data structure e.g. {a,{b,c},{d,{e,f},{g}}}, which I want to check
for NumericQ. For vectors and matrices I can use VectorQ[x,NumericQ] or
MatrixQ[x,NumericQ]. Is there a way to check an arbitrary data structure
that all elements are NumericQ or I have to construct a function for each
data structure?
Thanks in advance,
--Ted
