Collapse a visreg_list into a single visreg object

Takes a visreg_list, as produced by visreg_list() or visreg(), and collapses it down into a single visreg object. This is equivalent to calling visreg_list() with collapse = TRUE in the first place; it is provided separately so that a visreg_list can be collapsed after the fact, e.g. visreg_list(v1, v2) |> collapse().

Usage

collapse(x, labels)

Arguments

x

A visreg_list object.

labels

A character vector with length corresponding to the number of visreg objects in x that provides labels for the different objects in subsequent plots. If missing, the response variable names are used (or Y1, Y2, ... if these are not unique).

Value

A visreg object.

Examples

fit <- lm(Ozone ~ Solar.R + Wind + Temp, data = airquality)
v1 <- visreg(fit, "Wind", plot = FALSE, alpha = 0.2)
v2 <- visreg(fit, "Wind", plot = FALSE, alpha = 0.01)
labs <- c("Confidence: 0.80", "Confidence: 0.99")
vv1 <- visreg_list(v1, v2, collapse = FALSE) |> collapse(labels = labs)
vv2 <- visreg_list(v1, v2, collapse = TRUE, labels = labs)
identical(vv1, vv2)
#> [1] TRUE
