gg_partialR Documentation

Visualize effect estimates for specific covariate combinations

Description

Depending on the plot function and input, creates either a 1-dimensional slices, bivariate surface or (1D) cumulative effect.

Usage

gg_partial(data, model, term, ..., reference = NULL, ci = TRUE)

gg_partial_ll(
  data,
  model,
  term,
  ...,
  reference = NULL,
  ci = FALSE,
  time_var = "tend"
)

get_partial_ll(
  data,
  model,
  term,
  ...,
  reference = NULL,
  ci = FALSE,
  time_var = "tend"
)

Arguments

data

Data used to fit the model.

model

A suitable model object which will be used to estimate the partial effect of term.

term

A character string indicating the model term for which partial effects should be plotted.

...

Covariate specifications (expressions) that will be evaluated by looking for variables in x. Must be of the form z = f(z) where z is a variable in the data set and f a known function that can be usefully applied to z. Note that this is also necessary for single value specifications (e.g. age = c(50)). For data in PED (piece-wise exponential data) format, one can also specify the time argument, but see "Details" an "Examples" below.

reference

If specified, should be a list with covariate value pairs, e.g. list(x1 = 1, x2=50). The calculated partial effect will be relative to an observation specified in reference.

ci

Logical. Indicates if confidence intervals for the term of interest should be calculated/plotted. Defaults to TRUE.

time_var

The name of the variable that was used in model to represent follow-up time.
