qualif(x, which = "", ...)
qualif(x, which, check = TRUE) <- value
# S4 method for gbFeature
qualif(x, which, fixed = FALSE, use.names = TRUE)
# S4 method for gbFeature
qualif(x, which, check = TRUE) <- value
# S4 method for gbFeatureTable
qualif(x, which = "", fixed = FALSE,
  use.names = TRUE)
# S4 method for gbRecord
qualif(x, which = "", fixed = FALSE,
  use.names = TRUE)

Examples

# NOT RUN {
load(system.file("extdata", "marine_metagenome.rda", package = "biofiles"))

## use shortcuts to common qualifiers
