## Usage

```
plot_cme(
x,
effect = NULL,
condition = NULL,
type = "response",
vcov = NULL,
conf_level = 0.95,
draw = TRUE,
...
)
```

## Arguments

- condition
character vector or named list of length smaller than 4. Character vectors must be the names of the predictor variables to display. The names of the list must The first element is displayed on the x-axis. The second element determines the colors. The third element creates facets. Other variables are held at their means or modes. Lists can include these types of values:

Numeric vector

Function which returns a numeric vector or a set of unique categorical values

Shortcut strings for common reference values: "minmax", "quartile", "threenum"

- type
string indicates the type (scale) of the predictions used to compute contrasts or slopes. This can differ based on the model type, but will typically be a string such as: "response", "link", "probs", or "zero". When an unsupported string is entered, the model-specific list of acceptable values is returned in an error message. When

`type`

is`NULL`

, the default value is used. This default is the first model-related row in the`marginaleffects:::type_dictionary`

dataframe.- vcov
Type of uncertainty estimates to report (e.g., for robust standard errors). Acceptable values:

FALSE: Do not compute standard errors. This can speed up computation considerably.

TRUE: Unit-level standard errors using the default

`vcov(model)`

variance-covariance matrix.String which indicates the kind of uncertainty estimates to return.

Heteroskedasticity-consistent:

`"HC"`

,`"HC0"`

,`"HC1"`

,`"HC2"`

,`"HC3"`

,`"HC4"`

,`"HC4m"`

,`"HC5"`

. See`?sandwich::vcovHC`

Heteroskedasticity and autocorrelation consistent:

`"HAC"`

Mixed-Models degrees of freedom: "satterthwaite", "kenward-roger"

Other:

`"NeweyWest"`

,`"KernHAC"`

,`"OPG"`

. See the`sandwich`

package documentation.

One-sided formula which indicates the name of cluster variables (e.g.,

`~unit_id`

). This formula is passed to the`cluster`

argument of the`sandwich::vcovCL`

function.Square covariance matrix

Function which returns a covariance matrix (e.g.,

`stats::vcov(model)`

)

- conf_level
numeric value between 0 and 1. Confidence level to use to build a confidence interval.

- draw
`TRUE`

returns a`ggplot2`

plot.`FALSE`

returns a`data.frame`

of the underlying data.- ...
Additional arguments are passed to the

`predict()`

method supplied by the modeling package.These arguments are particularly useful for mixed-effects or bayesian models (see the online vignettes on the`marginaleffects`

website). Available arguments can vary from model to model, depending on the range of supported arguments by each modeling package. See the "Model-Specific Arguments" section of the`?marginaleffects`

documentation for a non-exhaustive list of available arguments.

## Examples

```
mod <- lm(mpg ~ hp + wt, data = mtcars)
plot_predictions(mod, condition = "wt")
mod <- lm(mpg ~ hp * wt * am, data = mtcars)
plot_predictions(mod, condition = c("hp", "wt"))
plot_predictions(mod, condition = list("hp", wt = "threenum"))
plot_predictions(mod, condition = list("hp", wt = range))
