Initialize Corpus Query Processor (CQP).

Source: R/cqp.R

CQP needs to know where to look for CWB indexed corpora. To initialize CQP, call cqp_initialize. To reset the registry, use the function cqp_reset_registry. To get the registry used by CQP, use cqp_get_registry. To get the initialization status, use cqp_is_initialized

cqp_initialize(registry = Sys.getenv("CORPUS_REGISTRY"))

cqp_is_initialized()

cqp_get_registry()

cqp_reset_registry(registry = Sys.getenv("CORPUS_REGISTRY"))

Arguments

registry

the registry directory

Examples

cqp_is_initialized() # check initialization status
#> [1] TRUE
if (!cqp_is_initialized()) cqp_initialize()
cqp_is_initialized() # check initialization status (TRUE now?)
#> [1] TRUE
cqp_get_registry() # get registry dir used by CQP
#> [1] "/var/folders/m_/431fjnbs1t32_62d35wvs7pr0000gp/T//Rtmp2Z1wFX/registry_tmp"

registry <- if (!check_pkg_registry_files()) use_tmp_registry() else get_pkg_registry()
if (cqp_get_registry() != registry) cqp_reset_registry(registry = registry)
cqp_list_corpora() # get list of corpora
#> [1] "UNGA"    "REUTERS"
