Arguments

fpath

(character(1))
File path.

pname

(character(1))
Parser name (e.g. "table4" - see docs).

schemas_all

(tibble())
Tibble with name, version and schema list-col.

delim

(character(1))
File delimiter.

...

Passed on to readr::read_delim.

Examples

path <- system.file("extdata/tool1", package = "nemo")
x <- Tool$new("tool1", pkg = "nemo", path)
schemas_all <- x$config$get_schemas_raw()
pname <- "table4"
fpath_latest <- file.path(path, "latest", "sampleA.tool1.table4.tsv")
fpath_v1 <- file.path(path, "v1.0.0", "sampleA.tool1.table4.tsv")
(d_latest <- parse_file_nohead(fpath_latest, pname, schemas_all))
