Arguments

type

Character string indicating the type of the vector; possible values: double,numeric,integer,logical,character,any.

reserve

The number of slots to be pre-allocated in the stdvector.

sdv

A stdvector object, as returned by stdvectorCreate.

...

optional arguments passed to inner print and toString methods. Unused.

x

A stdvector object, as returned by stdvectorCreate.

values

Values to be appended (in stdvectorPushBack) or set (in stdvectorReplace).

indexes

Indexes used to subset the current stdvector, in case of out of bounds indexes an error will be raised.

indexFrom

Used by stdvectorErase as starting index (inclusive) for the range of elements to be removed from stdvector.

indexTo

Used by stdvectorErase as ending index (inclusive) for the range of elements to be removed from stdvector.

  # create a stdvector

  # add 100 values to it
  for(i in 1:100){
    # note that sv is modified in-place
    stdvectorPushBack(sv,i)
  }
  # get a normal R vector from the stdvector
  v <- stdvectorToVector(sv)
