# will produce lints
lint(
  text = "sample(1:10, 2)",
  linters = sample_int_linter()
)

lint(
  text = "sample(seq(4), 2)",
  linters = sample_int_linter()
)

lint(
  text = "sample(seq_len(8), 2)",
  linters = sample_int_linter()
)

# okay
lint(
  text = "sample(seq(1, 5, by = 2), 2)",
  linters = sample_int_linter()
)

lint(
  text = "sample(letters, 2)",
  linters = sample_int_linter()
