R_base_tools/strings.html7_78_0.txt | Typically, however, your strings will be one column of a data frame, and
you’ll want to use filter instead:
df <- tibble(
word = words,
i = seq_along(word)
)
df %>%
filter(str_detect(word, "x$"))
#> # A tibble: 4 × 2

R_base_tools/stringr.html3_4_0.txt |
str_length("abc")
#> [1] 3
This is now equivalent to the base R function ` nchar() ` . Previously it was
needed to work around issues with ` nchar() ` such as the fact that it
returned 2 for ` nchar(NA) ` . This has been fixed as of R 3.3.0, so it is no
longer so important. | |

BRIGHT: stackoverflow
A format conversion of the standard passage-retrieval setting of
BRIGHT: A Realistic and Challenging Benchmark for Reasoning-Intensive Retrieval,
by the original BRIGHT authors. Source: xlangai/BRIGHT,
pinned to 3066d29c9651a576c8aba4832d249807b181ecae. This is a converted mirror, not an independently annotated dataset.
The original dataset is distributed under CC BY 4.0.
See SOURCE_README.md for the original dataset card and attribution.
| Table | Rows | Columns |
|---|---|---|
| corpus | 107,081 | id, title, text |
| queries | 117 | id, text |
| qrels | 478 | query-id, corpus-id, score |
| exclusions (optional) | 0 | query-id, corpus-id |
All published configs use the test split. corpus.text is exactly the original
documents.content; title is empty. Query IDs, document IDs and original examples.query
strings are preserved without normalization. qrels is the unique set of gold_ids pairs,
with binary score 1. Duplicate labels are collapsed; no relevance judgments are added.
Gold reasoning, gold answers, gold_ids_long, generated query rewrites and long_documents
are not part of the converted evaluation inputs.
This subset has no real excluded documents; the optional exclusions table is omitted.
The N/A exclusion sentinel is removed. Excluded IDs and positive IDs are validated against
the corpus and must be disjoint for each query. Keep ignore_identical_ids=false: matching
query/document ID strings alone do not imply a BRIGHT exclusion.
Evaluate each BRIGHT subset against its own complete corpus. Report nDCG@10 per subset and the unweighted mean across the 12 subsets. Record encoder context limits and truncation. The original evaluation code defines the protocol.
Converted with scripts/preprocess/dataset/convert_bright.py in the SPARSE project.
conversion.json records source and output SHA-256 hashes, row counts and validation checks.
