head(map)
# create a gpData object
gpTest <- create.gpData(pheno=pheno, geno=geno, map=map, repeated = c("loc", "wdh"), modCovar = c("loc", "wdh"))


O seguinte erro aparece : 
> gpTest <- create.gpData(pheno=pheno, geno=geno, map=map, repeated = c("loc", "wdh"), modCovar = c("loc", "wdh"))
Error: could not find function "create.gpData"


Alguém poderia me ajudar ???
Desde já agradeço.
