Revise column name in sample phenocovar data file
revise yaml format to have genotypes give explicit encodings
Another adjustment to grav sampledata
sample data: add '-' as possible missing value
read_cross2.R: initial draft
read_cross2: output to have class "cross2"
Remove sampledata; I'm going to re-do it using the 2nd replicate
New sample dataset: 2nd replicate from Moore et al (2013)
sampledata: Revise comment in yaml file
read_cross2: split genotypes and maps into lists by chromosome
.gitignore: ignore inst/doc/*.Rmd
.Rbuildignore: ignore stuff in inst/doc; finally read and understand format
Fix a couple of bugs in helper files for read_cross2
