Grouping of markers depending on correlation structure
1 | tagSNP(mat, threshold = 0.8)
|
mat |
(p x p) correlation matrix |
threshold |
lower value of correlation considered for grouping |
Grouping of markers is based on the correlation matrix. Apart from this, the strategy for grouping is similar to Carlson et al. (2004). A representative marker is suggested for each group.
list (LEN number of groups) of lists (LEN 2); marker names correspond to column names of mat
snps
vector of marker IDs in group
tagsnp
representative marker suggested for this group
