使用ggdotchart函数绘制Cleveland点图
加载所需R包
library(ggpubr)
基本用法：
Usage
ggdotchart(data, x, y, group = NULL, combine = FALSE, color = "black",
palette = NULL, shape = 19, size = NULL, dot.size = size,
sorting = c("ascending", "descending"), add = c("none", "segment"),
add.params = list(), x.text.col = TRUE, rotate = FALSE, title = NULL,
xlab = NULL, ylab = NULL, facet.by = NULL, panel.labs = NULL,
short.panel.labs = TRUE, select = NULL, remove = NULL, order = NULL,
label = NULL, font.label = list(size = 11, color = "black"),
label.select = NULL, repel = FALSE, label.rectangle = FALSE,
ggtheme = theme_pubr(), ...)
theme_cleveland(rotate = TRUE)常用参数
Arguments
data #所需数据框 a data framex, y #变量x和y x and y variables for drawing.group #分组变量 an optional column name indicating how the elements of x are grouped.combine #对于多类型数据是否分面 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.color, size #设置点的颜色和大小 points color and size.palette #自定义颜色画板 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".shape #设置点的形状 point shape. See show_point_shapes.dot.size #点的大小 numeric value specifying the dot size.sorting #设定升序还是降序排列 a character vector for sorting into ascending or descending order. Allowed values are one of "descending" and "ascending". Partial match are allowed (e.g. sorting = "desc" or "asc"). Default is "descending".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_mad", "median_range"; see ?desc_statby for more details.add.params #添加其他参数 parameters (color, size, linetype) for the argument 'add'; e.g.: add.params = list(color = "red").rotate #设置坐标轴水平还是垂直放置 logical value. If TRUE, rotate the graph by setting the plot orientation to horizontal.title #设置标题 plot main title.xlab #设置x轴标题 character vector specifying x axis labels. Use xlab = FALSE to hide xlab.ylab #设置y轴标题character vector specifying y axis labels. Use ylab = FALSE to hide ylab.facet.by #设置分组分面 character vector, of length 1 or 2, specifying grouping variables for faceting the plot into multiple panels. Should be in the data.panel.labs #设置分面各组的标题 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.select #选择需要展示的变量 character vector specifying which items to display.remove #移除不需要展示的变量 character vector specifying which items to remove from the plot.order #选定变量的排列顺序 character vector specifying the order of items.label #设置列标签 the name of the column containing point labels. Can be also a character vector with length = nrow(data).font.label #设置标签字体 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").repel #是否避字体免重叠 a logical value, whether to use ggrepel to avoid overplotting text labels or not.label.rectangle #是否给标签添加方框 logical value. If TRUE, add rectangle underneath the text, making it easier to read.ggtheme #设置画图主题 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(), ....... #设置其他参数 other arguments to be passed to geom_histogram and ggpar.使用示例
