我的R数据框data
(与dplyr
制造),我试图用ggplot()
绘制:目前我使用下面的代码绘制R:与position_dodge和ggplot注释geom_text微面
require(dplyr)
data <- structure(list(gGroup = structure(c(1L, 1L, 1L, 1L, 2L, 2L, 2L,
2L, 3L, 3L, 3L, 3L), .Label = c("MC", "R", "UC"), class = "factor"),
Episode = structure(c(2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L,
2L, 2L, 2L), .Label = c("Morning", "Day", "Night", "24 hour"
), class = "factor"), variable = c("HF", "HF", "LF", "LF",
"HF", "HF", "LF", "LF", "HF", "HF", "LF", "LF"), parameter = c("RR",
"RT", "RR", "RT", "RR", "RT", "RR", "RT", "RR", "RT", "RR",
"RT"), mean = c(3.90575222833804, 4.24572828952087, 5.14491629837998,

"Episode", "variable", "parameter", "mean", "sd", "se"), class = c("grouped_df",
"tbl_df", "tbl", "data.frame"), row.names = c(NA, -12L), drop = TRUE, indices = list(
0:1, 2:3, 4:5, 6:7, 8:9, 10:11), group_sizes = c(2L, 2L,
2L, 2L, 2L, 2L), biggest_group_size = 2L, labels = structure(list(

"LF", "HF", "LF")), .Names = c("gGroup", "Episode", "variable"
), class = "data.frame", row.names = c(NA, -6L)))
:
require(ggplot2)
require(ggthemes)
pd <- position_dodge(width=0.9)
p <- ggplot(data, aes(x = gGroup, y = mean, fill = variable)) +
facet_grid(parameter~Episode) +
geom_bar(stat="identity", position=pd) +
geom_errorbar(aes(ymin = mean-se, ymax = mean+se), width = .3, position=pd) +
theme_hc() + scale_fill_hc() +
labs(y = "Logit transform of spectral power (m/s2), mean±SE", x= NULL)
ann_text <- data.frame(gGroup = "MC", mean = 6, variable = "LF", parameter = "RR", Episode = "Day")
p + geom_text(aes(ymax = 6.5, width = .2), data = ann_text, label="*", position=pd)
这给了我下面的情节:
我很结果令人满意,但正如您所看到的星号未正确对齐。我在网上查了一下,我读了this和this和手册。 每个人都看到使用position=position_dodge(width=0.9)
的建议,但这对我没有帮助。我试过hjust
可能会将星号移到正确的位置,但这也是没有用的。有趣的是,我的错误栏正确对齐。
我觉得我可以忽略一些非常简单的东西,但我无法弄清楚它是什么。 我在OSX 10.10.2上使用R 3.1.3,并加载最新版本的ggplot2
和ggthemes
。
用的东西[最小再现的示例](http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example)是它们应该是最小的,并重复性。你的例子既不是。 – shadow 2015-03-13 15:30:27
感谢您的评论! 我添加了一个dput和一些关于加载包的信息。我可以用提供的代码重现我的问题。我应该提供其他信息吗? – Jasper 2015-03-13 15:59:06
