plot function

Plot a smn.lmm or smsn.lmm object

Fitted values versus residuals plot.

## S3 method for class 'SMN'
plot(x, type = "response", level = "conditional",
     useweight = TRUE, alpha = 0.3, ...)

## S3 method for class 'SMSN'
plot(x, type = "response", level = "conditional",
     useweight = TRUE, alpha = 0.3, ...)

Arguments

• x: An object inheriting from class SMN or SMSN, representing a fitted scale mixture of (skew) normal linear mixed model.
• type: Type of residual that should be used. For details see residuals.SMN. Default is "response", indicating raw residuals.
• level: Level of residual that should be used. For details see residuals.SMN. Default is "conditional".
• useweight: A logical value indicating if the estimated weights should be used as color in the plot.
• alpha: Transparency parameter to be used (0<alpha<1). Meaningless if useweight = TRUE.
• ...: Additional arguments.

Returns

A ggplot object.
