label_size in ggarrange() ?

[G-Thomson]

In cowplot the plot.grid() function has the label_size option to change the size of labels?

Could this be implemented in ggarrange() too?

Hi,

as the argument font.label is used in many ggpubr functions (see ggboxplot) to customize labels, I keep the same naming convention for ggarrange().

New arguments in ggarrange() to customize plot labels:
- font.label
- label.x and label.y
- hjust and vjust

Examples:

library(ggpubr)
data("ToothGrowth")
df <- ToothGrowth
df$dose <- as.factor(df$dose)

# Create some plots
# ::::::::::::::::::::::::::::::::::::::::::::::::::
bxp <- ggboxplot(df, x = "dose", y = "len",
    color = "dose", palette = "jco")
dp <- ggdotplot(df, x = "dose", y = "len",
    color = "dose", palette = "jco")
dens <- ggdensity(df, x = "len", fill = "dose", palette = "jco")

# Arrange
# ::::::::::::::::::::::::::::::::::::::::::::::::::
ggarrange(bxp, dp, dens, ncol = 2, nrow = 2,
          labels = c("A", "B", "C"),
          font.label = list(size = 16, color = "red"))

Nice. It really works

Hi, I'm beginner with R and I'm learning for my thesis data analysis (and fancy custom presentation of results), I want to know how can i center the graphic labels, because it looks on the y axis at the boxplot.

I'm using this code:
ggarrange(q, s, u, w, y, d, f, h, j, ncol = 3, nrow = 3,
labels = c("LT", "LA", "LE", "TD", "LH", "L1", "L2", "L3", "L1L2"),
font.label = list(size = 16, color = "black"), common.legend = TRUE, legend = "top")
for the plots (example):
p<-ggplot(data, aes(x=Embalse, y=LT, fill=Embalse)) +
geom_boxplot()
q <- p+ stat_summary(fun.y=mean, geom="point", shape=1, size=3)+theme_classic()+theme(axis.title = element_blank())
and same for the rest variables.

UPDATE:
tried with hjust=-8, vjust= 0.6 but can't get all panel labels centered, some are more at the left and some more at the right, and some, yes, centered (it's a 3x3 panels-plots).

what's wrong?
thanks for your help.
