+# Description
+
+R/qtl2 handles multi-parent populations, such as DO, HS rat and the collaborative cross (CC). It also comes with an LMM implementation. Here we describe using and embedding R/qtl2 in GN2.
+
+# Tasks
+
+
+## R/qtl2
+
+R/qtl2 is packaged in guix and can be run in a shell with
+
+
+```
+guix shell -C r r-qtl2
+R
+library(qtl2)
+```
+
+R/qtl2 also comes with many tests. When starting up with development tools in the R/qtl2 checked out git repo
+
+```sh
+cd qtl2
+guix shell -C -D r r-qtl2 r-devtools make coreutils gcc-toolchain
+make test
