A TwasWeightsRow object.

Examples

twe <- twasWeightsRow(
  variantIds = sprintf("chr1:%d:A:G", 100L * (1:4)), weights = rep(0.1, 4),
  cvResult = list(rsq = 0.5), weightStandardized = FALSE)
tw <- TwasWeights(studyName = "s1", context = "brain", trait = "g1",
  method = "susie", entry = list(twe))
twasWeights(tw, studyName = "s1", context = "brain", trait = "g1",
  method = "susie")
