Tibble doesn't recycle difftimes properly. #284

Thanks. AFAIK, tibbles recycle only length-1 vectors. |

Bug fixes --------- - Values of length 1 in a `tibble()` call are recycled prior to evaluating subsequent arguments, improving consistency with `mutate()` (#213). - Recycling of values of length 1 in a `tibble()` call maintains their class (#284). - `add_row()` now always preserves the column data types of the input data frame the same way as `rbind()` does (#296). - `lst()` now again handles duplicate names, the value defined last is used in case of a clash. - Adding columns to zero-row data frames now also works when mixing lengths 1 and 0 in the new columns (#167). - The `validate` argument is now also supported in `as_tibble.tbl_df()`, with default to `FALSE` (#278). It must be passed as named argument, as in `as_tibble(validate = TRUE)`. Formatting ---------- - `format_v()` now always surrounds lists with `[]` brackets, even if their length is one. This affects `glimpse()` output for list columns (#106). - Factor levels are escaped when printing (#277). - Non-syntactic names are now also escaped in `glimpse()` (#280). - `tibble()` gives a consistent error message in the case of duplicate column names (#291).

If a
difftime
variable is included in a tibble, and the specified number of observations is equal to the other variable(s), then the class of the variable is maintained.However, if the specified number of observations in the
difftime
variable is a proper factor of the number of observations in the other variable, so that thedifftime
variable is recycled, then the class of the variable silently changes tonumeric
:From the StackOverflow link, this may be occurring because
tibble::tibble
uses as.vector if recycling is necessary, which strips the attributes of the vector.The text was updated successfully, but these errors were encountered:
