R- ggplot labs(subtitle=...和caption=...)不工作
R- ggplot labs(subtitle=...和caption=...)不工作
提问于 2018-11-24 00:26:28
在将文本元素正确添加到某些图表中的绘图时，我遇到了问题。我使用ggplot2和+ labs(...)但是只有一些元素包含在我的图中。
这是其中一个图表：
colnames(dane.trust)[1] = "Country" #GEO.INDIC_WB
w5 <- ggplot(dane.trust, aes(x = reorder(Country, Trust.Index), y = Trust.Index, fill=Country)) + scale_fill_brewer(palette = "Set2")
w5 + geom_bar(stat="identity") + #guides(fill=FALSE) +
geom_text(data=dane.trust[,c(1,6)], label = round(Trust.Index, digits = 2),vjust = -0.5, aes(inherit.aes = TRUE, fontface=2)) +
theme_bw() + labs(x="", y="Average Rating (0-10)", title = "Overall trust levels", subtitle="Index of trust to political and legal systems, police and others") +
theme(title = element_text(face = "bold", color = "black"), axis.title = element_text(face = "bold", color = "black"), panel.grid.major.x = element_blank())Title、x.label和y.label运行得很好，但我看不到字幕和标题。
没有错误，只是那些元素不存在。
有没有人知道问题出在哪里？
EDIT1:这是> dput(dane.trust)的输出
structure(list(Country = structure(1:5, .Label = c("Bulgaria",
"Hungary", "Poland", "Romania", "Slovakia"), class = "factor"),
Trust.in.the.political.system = c(2.6, 4.5, 3.5, 4.8, 3.5
), Trust.in.the.police = c(3.6, 5.7, 5.2, 6.4, 4.4), Trust.in.others = c(4.2,
5.3, 6, 6.4, 5.8), Trust.in.the.legal.system = c(3, 5.1,
4.2, 5.8, 3.6), Trust.Index = c(3.35, 5.15, 4.725, 5.85,
4.325)), .Names = c("Country", "Trust.in.the.political.system",
"Trust.in.the.police", "Trust.in.others", "Trust.in.the.legal.system",
"Trust.Index"), row.names = c(NA, -5L), class = "data.frame")EDIT2:我刚刚在另一台计算机上检查了我的原始代码，它工作了。是什么导致了这种情况？
好了，在重新安装R和RStudio之后，一切都正常了，感谢大家的回答:)。

这样就可以了
w5 <- ggplot(dane.trust, aes(x = reorder(Country, Trust.Index), y = Trust.Index, fill=Country)) + scale_fill_brewer(palette = "Set2")
w5 + geom_bar(stat="identity") + #guides(fill=FALSE) +
geom_text(vjust = -0.5, aes(fontface=2), label = dane.trust$Trust.Index) +
theme_bw() + labs(x="", y="Average Rating (0-10)", title = "Overall trust levels", subtitle="Index of trust to political and legal systems, police and others") +
theme(title = element_text(face = "bold", color = "black"), axis.title = element_text(face = "bold", color = "black"), panel.grid.major.x = element_blank())如果提供了Trust.Index，则geom_text()中的参数label只能计算aes()内的data。您可以在aes()外部的label = ...中指定向量，也可以在aes()内部插入label =...，如下所示：geom_text(data = dane.trust[, c(1, 6)], ..., aes(label = Trust.Index))
