The gateR package is a suite of R functions to identify significant spatial clustering of mass and flow cytometry data used in immunological investigations. The gateR package can be used for a panel of all surface markers, or a mixture of surface markers and functional read outs. The gateR package performs a gating technique that estimates statistically significant fluorescent marker combination values within which one immunologically distinctive group (i.e., disease case) is more associated than another group (i.e., healthy control), successively, using various combinations (i.e., "gates") of fluorescent markers to examine features of cells that may be different between groups. For a two-group comparison, the gateR package uses the spatial relative risk function that is estimated using the [sparr](https://CRAN.R-project.org/package=sparr) package. The gates are conducted in two-dimensional space comprised of two fluorescent markers.
