One can define the irreducible components of an analytic space (see [Con99]). A compact analytic space $Z$ has finitely many irreducible components $Z_{i}$. Then we define the cycle ${\rm cyc}(Z)$ associated to $Z$ as a positive formal ${\mathbb{Z}}$-linear combination of the irreducible components $Z_{i}$ by restriction to affinoid subdomains and then by glueing (see [Gu98], §2). One can show that the weighted $n$-dimensional polyhedral complex $({\varphi_{\rm trop}})_{*}({\rm cyc}(Z))$ depends only on ${\rm cyc}(Z)$ and this dependence is linear. We leave the details to the reader.
