ggplot geom_errorbar？
ggplot geom_errorbar？

我的数据看起来像这样：
df1 <-
structure(
list(
y = c(-0.19, 0.3,-0.05, 0.15,-0.05, 0.15),
lb = c(-0.61,
0.1,-0.19,-0.06,-0.19,-0.06),
ub = c(0.22, 0.51, 0.09, 0.36,
0.09, 0.36),
x = structure(
c(1L, 2L, 1L, 2L, 1L, 2L),
.Label = c("X1",
"X2"),
class = "factor"
),
Group = c("A", "A", "B", "B", "C",
"C")
),
.Names = c("y", "lb", "ub", "x", "Group"),
row.names = c(NA,-6L),
class = "data.frame"
)我想用ggplot2绘制由group着色的带有错误条lb, ub的点x,y。因为x是离散的，所以我想要jitter，这样点和条就不会重叠。现在，我可以对点执行jitter操作，但不能对直线执行操作。另外，我希望点的顺序是A，B，C
ggplot(data = df1, aes(x, y, color = Group)) + geom_point(size = 4, position = "jitter") +
geom_errorbar(
aes(ymin = lb, ymax = ub),
width = 0.1,
linetype = "dotted"
) +
geom_hline(aes(yintercept = 0), linetype = "dashed") + theme_bw()

可以使用position_dodge来获得所需的顺序和在点位置绘制的误差线
ggplot(data = df1, aes(x, y, color = Group)) +
geom_point(size = 4, position=position_dodge(width=0.5)) +
geom_errorbar(
aes(ymin = lb, ymax = ub),
width = 0.1,
linetype = "dotted",
position=position_dodge(width=0.5)) +
geom_hline(aes(yintercept = 0), linetype = "dashed") +
theme_bw()

如果你想要抖动，我会这样做：
ggplot(data = df1, aes(x, y, color = Group)) +
geom_pointrange(aes(ymin = lb, ymax = ub),
position=position_jitter(width=0.5),
linetype='dotted') +
theme_bw()
