Prepare ERA Data for XY Plot

PrepareXY standardizes ERA column names for use in generalized plotting functions that require selection of two out of three of the higher order ERA concepts of practice, outcome and product.

PrepareXY(
  Data,
  Comparison,
  CodeAxes = c("Yes", "Yes"),
  PLevel,
  OLevel,
  EULevel
)

Arguments

Data

a data.frame or data.table of ERA data (e.g. ERA.Compiled).

Comparison

a character vector of length one; accepted values: PxO practice vs. outcome,PxEU practice vs. product (experimental unit) or OxEU outcome vs. product. These are the respective x and y axes to be used in plotting.

CodeAxes

a character vector of length two; accepted values: Yes or No; default = c("Yes","Yes"); When set to Yes axes show coded names, when No axes show full names. Position 1 of this parameters refers to the x-axis and position 2 the y-axis of plots.

PLevel

character vector of length one; accepted values: T theme, P practice or S subpractice. This parameter indicates the practice level for analysis.

OLevel

character vector of length one; accepted values: P pillar, SP subpillar, I indicator or SI subindicator. This parameter indicates the outcome level for analysis.

EULevel

character vector of length one; accepted values: T type, S subtype or P product. This parameter indicates the product level for analysis. Note products are also referred to as experimental units (EU) in ERA.

Value

PrepareXY returns a list with two elements:

• [[Data]] returns a data.table of the supplied dataset with focal columns renamed to Axis1, Axis2 and Group.

• [[Lab]] returns a character vector of names corresponding to Axis1, Axis2 and Group.
