Package: SpaTopic Type: Package Title: Topic Inference to Identify Tissue Architecture in Multiplexed Images Version: 1.3.1.9000 Date: 2026-05-27 Authors@R: c( person("Xiyu", "Peng", email = "pansypeng124@gmail.com", role = c("aut", "cre"),comment = c(ORCID = "0000-0003-4232-0910")), person("Nikki", "Xiao", email = "xmq041117@gmail.com", role = c("aut")) ) Description: A novel spatial topic model to integrate both cell type and spatial information to identify the complex spatial tissue architecture on multiplexed tissue images without human intervention. The Package implements a collapsed Gibbs sampling algorithm for inference. The method is highly scalable to large-scale image datasets without extracting neighborhood information for every single cell. The package supports spatially resolved cell-level data analysis, topic inference, visualization, and downstream biological interpretation of tissue microenvironments.
