In hutilscpp: Miscellaneous Functions in C++

Parallel fastmatching

Description

fastmatch::fmatch and logical versions, with parallelization.

Usage

fmatchp(
  x,
  table,
  nomatch = NA_integer_,
  nThread = getOption("hutilscpp.nThread", 1L),
  fin = FALSE,
  whichFirst = 0L,
  .raw = 0L
)

finp(x, table, nThread = getOption("hutilscpp.nThread", 1L), .raw = 0L)

fnotinp(x, table, nThread = getOption("hutilscpp.nThread", 1L), .raw = 0L)

Arguments

x, table, nomatch	As in match.
nThread	Number of threads to use.
fin	TRUE | FALSE Behaviour of return value when value found in table. If FALSE, return the index of table; if TRUE, return TRUE.
whichFirst	integer(1) If 0L, not used. If positive, returns the index of the first element in x found in table; if negative, returns the last element in x found in table.
.raw	integer(1) 0 Return integer or logical as required. 1 Return raw if possible.

Examples

x <- c(1L, 4:5)
y <- c(2L, 4:5)
fmatchp(x, y)
fmatchp(x, y, nomatch = 0L)
finp(x, y)
