Compare multiple core inflation measures

Takes multiple ik_core objects and facilitates side-by-side comparison. Produces summary statistics and a multi-line chart of all measures.

Usage

ik_compare(..., labels = NULL)

Arguments

...

One or more objects of class "ik_core", as returned by ik_core().

labels

Character vector or NULL. Labels for each measure. If NULL, labels are derived from each object's method name.

Value

An S3 object of class "ik_comparison" with elements:

measures

List of ik_core objects.

labels

Character vector of labels.

Examples

data <- ik_sample_data("components")
core_tm <- ik_core(data, method = "trimmed_mean")
core_wm <- ik_core(data, method = "weighted_median")
core_ex <- ik_core(data, method = "exclusion", exclude = c("Food", "Transport"))

comp <- ik_compare(core_tm, core_wm, core_ex)
print(comp)
