bcMVNmtQTL {FastMtQTL} | R Documentation |
This function calculates the LOD (log of odds) for multi-trait QTL analysis using the properties of multivariate normal distribution.
bcMVNmtQTL(inData, phenoCols, Chrs, markerInterval=1.01)
inData |
Input data set for multi-trait QTL analysis. |
phenoCols |
Column numbers in the phenotype matrix which should be used in the analysis. |
Chrs |
Vector of chromosome number(s) for which LOD scores should be calculated. |
markerInterval |
Maximum distance (in cM) between positions at which the genotype probabilities are calculated, though for step = 0, probabilities are calculated only at the marker locations. |
It will return a dataframe with the values of log of odds (LOD) statistic for multi-trait QTL mapping.
