),
which provides a cross2
object to use with that package. Alternatively there's also data
available from the R/qtl2data repository.
This package was written mostly for personal convenience to help in performing QTL mapping in the Arabidopsis multiparent advanced generation intercross (MAGIC) lines (described in Kover P .. Mott R 2009).
This might however be useful for anyone using the Arabidopsis MAGIC lines. It
depends on the happy.hbrem
package,
which can be installed from https://github.com/tavareshugo/happy.hbrem
The package implements the same linear model approach in the available scripts, but with some more flexibility for specifying models and outputs tabular data that is convenient for downstream analysis and plotting.
To install this package, launch R and issue the following commands:
if(!require("remotes")) install.packages("remotes")
if(!require("happy.hbrem")) remotes::install_github("tavareshugo/happy.hbrem")
remotes::install_github("tavareshugo/MagicHelpR")
# If the above fails (it has done for me in Ubuntu), then do this instead
remotes::install_git("git://github.com/tavareshugo/MagicHelpR.git")
There's also a basic introduction vignette.
