- data
a data frame
- x
character string containing the name of x variable.
- y
character vector containing one or more variables to plot
- combine
logical value. Default is FALSE. Used only when y is a vector
containing multiple variables to plot. If TRUE, create a multi-panel plot by
combining the plot of y variables.
- merge
logical or character value. Default is FALSE. Used only when y is
a vector containing multiple variables to plot. If TRUE, merge multiple y
variables in the same plotting area. Allowed values include also "asis"
(TRUE) and "flip". If merge = "flip", then y variables are used as x tick
labels and the x variable is used as grouping variable.
- color
outline color.
- fill
fill color.
- palette
the color palette to be used for coloring or filling by groups.
Allowed values include "grey" for grey color palettes; brewer palettes e.g.
"RdBu", "Blues", ...; or custom color palette e.g. c("blue", "red"); and
scientific journal palettes from ggsci R package, e.g.: "npg", "aaas",
"lancet", "jco", "ucscgb", "uchicago", "simpsons" and "rickandmorty".
- title
plot main title.
- xlab
character vector specifying x axis labels. Use xlab = FALSE to
hide xlab.
- ylab
character vector specifying y axis labels. Use ylab = FALSE to
hide ylab.
- facet.by
character vector, of length 1 or 2, specifying grouping
variables for faceting the plot into multiple panels. Should be in the data.
- panel.labs
a list of one or two character vectors to modify facet panel
labels. For example, panel.labs = list(sex = c("Male", "Female")) specifies
the labels for the "sex" variable. For two grouping variables, you can use
for example panel.labs = list(sex = c("Male", "Female"), rx = c("Obs",
"Lev", "Lev2") ).
- short.panel.labs
logical value. Default is TRUE. If TRUE, create short
labels for panels by omitting variable names; in other words panels will be
labelled only by variable grouping levels.
- shape
point shape
- size
Numeric value (e.g.: size = 1). change the size of points and
outlines.
- select
character vector specifying which items to display.
- remove
character vector specifying which items to remove from the plot.
- order
character vector specifying the order of items.
- add
character vector for adding another plot element (e.g.: dot plot or
error bars). Allowed values are one or the combination of: "none",
"dotplot", "jitter", "boxplot", "point", "mean", "mean_se", "mean_sd",
"mean_ci", "mean_range", "median", "median_iqr", "median_hilow",
"median_q1q3", "median_mad", "median_range"; see ?desc_statby for more
details.
- add.params
parameters (color, shape, size, fill, linetype) for the
argument 'add'; e.g.: add.params = list(color = "red").
- error.plot
plot type used to visualize error. Allowed values are one of
c("pointrange", "linerange", "crossbar", "errorbar", "upper_errorbar",
"lower_errorbar", "upper_pointrange", "lower_pointrange", "upper_linerange",
"lower_linerange"). Default value is "pointrange" or "errorbar". Used only
when add != "none" and add contains one "mean_*" or "med_*" where "*" = sd,
se, ....
- label
the name of the column containing point labels. Can be also a
character vector with length = nrow(data).
- font.label
a list which can contain the combination of the following
elements: the size (e.g.: 14), the style (e.g.: "plain", "bold", "italic",
"bold.italic") and the color (e.g.: "red") of labels. For example font.label
= list(size = 14, face = "bold", color ="red"). To specify only the size and
the style, use font.label = list(size = 14, face = "plain").
- label.select
can be of two formats:
- repel
a logical value, whether to use ggrepel to avoid overplotting
text labels or not.
- label.rectangle
logical value. If TRUE, add rectangle underneath the
text, making it easier to read.
- jitter
the amount of jitter.
- position
position adjustment, either as a string, or the result of a
call to a position adjustment function. Used to adjust position for
multiple groups.
- ggtheme
function, ggplot2 theme name. Default value is theme_pubr().
Allowed values include ggplot2 official themes: theme_gray(), theme_bw(),
theme_minimal(), theme_classic(), theme_void(), ....
- ...
other arguments to be passed to
geom_jitter, ggpar and
facet.
