Package: spacescans Type: Package Title: Link Time-Referenced Geolocation Data to the Spatial and Contextual Exposome Version: 0.3.4 Authors@R: c( person("Xuguang", "Ai", email = "xuguang.ai@outlook.com", role = c("aut", "cre")), person("Regenstrief Institute", role = "aut")) Description: R client for the 'spacescans' 'Python' pipeline, which links time-referenced geolocation data (location episodes of study participants) to the spatial and contextual exposome and returns one row per participant or per location episode. The pipeline runs in a separate 'Python' process that the package talks to through JSON request and result files and 'Parquet' tables, so a crash or an interrupt in 'Python' never takes the R session down. 'ss_install()' builds the 'Python' environment with 'uv'.
