Dimensions of a dataset

Usage

dimensions(x)

dimensions(x, sdmx_attributes = NULL) <- value

Arguments

x: A data.frame or inherited tibble, data.frame, or a structured list.
sdmx_attributes: The optional dimensions and attributes that conform with SDMX. c("time", "geo") will mark the "time" and "geo" attributes as conforming to sdmx. See sdmx-attribute.
value: The name or column number of the within the dataset.

Value

A data frame of the names, class, isDefinedBy, and codeList properties of the dimensions columns of the dataset following the datacube model.

Details

Do not confuse with base::dim. The dimension in the definition of the DataSet is different from the 'dimension' definition of the R language.

Examples

df <- data.frame ( sex = c("M", "F"), value = c(1,2), unit = c("NR", "NR"))
dimensions(df, sdmx_attributes = "sex") <- "sex"
measures(df) <- "value"
attributes_measures(df) <- "unit"
dimensions(df)

#> sex   sex character
