klassR (version 1.0.2)

update_klass: Update multiple Klass codes to a desired date.

Description

Update multiple Klass codes to a desired date.

Usage

update_klass(
  codes,
  dates = NA,
  classification = NULL,
  date = NULL,
  graph = klass_graph(classification, date),
  output = "code",
  report = FALSE,
  combine = TRUE
)

Value

If output = "code", a vector of length length(codes)

containing either a code if the update is successful or NA if the code has been split. If combine = FALSE, a code being combined with another code will also return NA.

If output == TRUE, a list of length length(codes) containing

data.frames detailing the codes visited through the node search. The tables have the following columns.

---

If report == TRUE and length(output) > 1 | TRUE, the result will be a list of data.frames with number of rows equal to the number of codes in the sequence of changes between the input codes and output codes. The columns in the data.frames are specified with

output.

If report == TRUE and length(output) == 1, the result will be a list of character vectors with length equal to the number of codes in the sequence of changes between the input code and output code. The contents of the character vectors is specified with output.

If report == FALSE and length(output) > 1 | TRUE the result will be a list of data.frames with one row representing the last code in the change sequence and columns specified by output. If a code has been split, the result will be NA. If combine == FALSE and a code is the result of a combination of codes, the result will be NA.

If report == FALSE and length(output) == 1, the result will be a character vector containing information about the updated codes specified by output. If a code has been split, the result will be

NA. If combine == FALSE and a code is the result of a combination of codes, the result will be NA.

Arguments

codes

Codes to be updated.

dates

Optional. Can be used to specify what date each of the codes was valid in. Supply a character vector of either length 1 to specify the same valid date for all codes, or of the same length as codes to specify valid dates for each code. The character vector(s) should have a format coercible by as.Date, e.g. YYYY-MM-DD. The function will return an error if a code was not valid at the specified date.

classification

The ID of the desired classification.

date

Optional. Can be used to specify the date the codes should be updated to, e.g. if you have codes that are valid in year T, but want to change the codes to the corresponding version in year T-1. If unspecified (the default), the function will update codes to the most recent version.

graph

Optional. A graph object generated by klass_graph. If you're making multiple calls to [update_klass], you can save some time by generating the graph beforehand and reusing it for each call to [update_klass] with this parameter. If providing the graph directly, you do not need to provide the classification and date parameters.

output

Either a character vector, containing one or more of the items in the list below, or TRUE to include all columns.

"code"

The Klass code.

"name"

The Klass name.

"validFrom"

The date that the code is valid from.

"validTo"

The date that the code is valid to.

"split"

Logical: Does the code split into two or more codes?

"combined"

Logical: Does two or more codes become this code?

"nextCode"

If split == FALSE, gives the code this code changed into. NA otherwise.

report

TRUE or FALSE. See the return section.

combine

TRUE or FALSE. See the return section.

Examples

library(klassR)
codes <- get_klass(131, date = "2020-01-01")[["code"]]

if (FALSE) {
updated_codes <- update_klass(codes,
  dates = "2020-01-01",
  classification = 131
)
}
