plot.ls_means function

Bar Plots of LS-Means

Bar plots of LS-means using the ggplot2 package.

## S3 method for class 'ls_means'
plot(x, y = NULL, which = NULL, mult = TRUE, ...)

Arguments

• x: an ls_means object.
• y: not used and ignored with a warning.
• which: optional character vector naming factors for which LS-means should be plotted. If NULL (default) plots for all LS-means are generated.
• mult: if TRUE and there is more than one term for which to plot LS-means the plots are organized in panels with facet_wrap.
• ...: currently not used.

Returns

generates the desired plots and invisibly returns the plot objects.

Examples

# Fit example model with 2 factors:
data("cake", package="lme4")
cake$Temp <- factor(cake$temperature, ordered = FALSE)
model <- lmer(angle ~ recipe * Temp + (1|recipe:replicate), cake)

# Extract LS-means:
(lsm <- ls_means(model))

# Multi-frame plot of the LS-means
plot(lsm)

# Compute list of 'single frame' plots:
res <- plot(lsm, mult=FALSE)

# Display each plot separately:
plot(res[[1]])
plot(res[[2]])

# Example with pairwise differences of LS-means:
(lsm <- ls_means(model, pairwise = TRUE))
plot(lsm, which="Temp")
