下面就是在R中利用ggplot画出带有error bar的简单斜率图的基本步骤。 首先,导入数据,test_data是一个只含有3个变量的数据集,分别为自变量X,调节变量M和因变量Y,三个变量均为连续变量。 library(readxl) test_data <- read_excel("Desktop/test_data.xlsx", col_types = c("numeric", "numeric", "numeric...
library(ggplot2) # 创建一个数据框 data <- data.frame( group = rep(LETTERS[1:4], each = 3), value = c(2, 3, 4, 8, 6, 5, 10, 9, 7), sd = c(0.5, 0.8, 0.7, 1.2, 0.9, 1.1, 0.6, 0.7, 0.8) ) # 绘制分组柱形图并添加errorbar plot <- ggplot(data, aes(x = group, ...
ggplot(tgc, aes(x = dose, y = len, colour = supp)) + geom_errorbar(aes(ymin = len - ci, ymax = len + ci), width = 0.1, position = pd) + geom_line(position = pd) + geom_point(position = pd) 黑色的误差线 - 注意 'group=supp' 的映射 -- 没有它,误差线将不会避开(就...
rownames(a)=c('Normal','Cancer') 接下来就是先绘制Bar图。 b <- barplot(a$mean, names.arg =rownames(a), col = c("green", "blue"), ylim = c(0, 20),axes = F, font = 2) 核心的部分来了,那就是生成标准差的的顶部横线。 arrows(b[1], a$mean[1], b[1], a$sd[1],angle...
It is possible to change error bar types thanks to similar function:geom_crossbar(),geom_linerange()andgeom_pointrange(). Those functions works basically the same as the most commongeom_errorbar(). # Load ggplot2library(ggplot2)# create dummy datadata <-data.frame(name=letters[1:5],value...
discrimination_plot <- ggplot(discrimination, aes(y = rank, x = Mean)) + geom_point(shape = 18, size = 1) + geom_errorbarh(aes(xmin = cilow, xmax = cihigh), height = 0.25) + geom_vline(xintercept = 0, color = "red", linetype = "dashed", cex = 1, alpha = 0.5) + ...
ggplot(data, aes(Group, Mean))+# ggplot function draws plot properlygeom_bar(stat="identity") The output of the previous R syntax is shown in Figure 1: A ggplot2 barchart. The error message does not appear anymore. Video & Further Resources ...

ggplot(data, aes(x1, x2)) + # Try to create plot geom_point() # Error in .Call.graphics(C_palette2, .Call(C_palette2, NULL)) : # invalid graphics stateThis code may sometimes work perfectly fine. However, it might happen that the error message “invalid graphics state” is ...
