In rsample: General Resampling Infrastructure

simple numerics

Code
  str1b <- make_strata(x1, depth = 500)
Condition
  Warning:
  The number of observations in each quantile is below the recommended threshold of 500.
  * Stratification will use 2 breaks instead.

simple character

Code
  str2a <- make_strata(x2, pool = 0.05)
Condition
  Warning:
  Stratifying groups that make up 5% of the data may be statistically risky.
  i Consider increasing `pool` to at least 0.1.

Code
  str2b <- make_strata(x2, pool = 0.05)
Condition
  Warning:
  Stratifying groups that make up 5% of the data may be statistically risky.
  i Consider increasing `pool` to at least 0.1.

bad data

Code
  s0 <- make_strata(x3)
Condition
  Warning:
  Too little data to stratify.
  * Resampling will be unstratified.

Code
  s1 <- make_strata(x3, pool = 0.06)
Condition
  Warning:
  Stratifying groups that make up 6% of the data may be statistically risky.
  i Consider increasing `pool` to at least 0.1.

Code
  s2 <- make_strata(mtcars$mpg)
Condition
  Warning:
  The number of observations in each quantile is below the recommended threshold of 20.
  * Stratification will use 1 breaks instead.
  Warning:
  Too little data to stratify.
  * Resampling will be unstratified.

Code
  s3 <- make_strata(seq_len(50), breaks = -1)
Condition
  Warning:
  The bins specified by `breaks` must be >=2.
  * Resampling will be unstratified.

don't stratify on Surv objects

Code
  check_strata("surv", df)
Condition
  Error:
  ! strata cannot be a <Surv> object.
  i Use the time or event variable directly.
