我正在尝试在情节中使用女性符号♀。这是非常模糊的(嗯,在我的实际图形上看起来是模糊的),所以我希望将其变为大胆的面孔。
df <- data.frame(x = c(0, 1), y = c(0, 1))
ggplot(df, aes(x, y)) + geom_point() +
theme_bw() +
annotate("text", x = 0.5, y = 0.7, label = "2016 ♀",
size = 7, hjust = 0, colour = "grey50")
我已经尝试了以下方法,但似乎都没有效果:
ggplot(df, aes(x, y)) + geom_point() +
annotate("text", x = 0.5, y = 0.7, label = "2016~bold(♀)",
size = 7, hjust = 0, parse = TRUE)
# error message: Error in parse(text = as.character(lab)) : <text>:1:11: unexpected '<'
#1: 2016~bold(<
^
ggplot(df, aes(x, y)) + geom_point() +
annotate("text", x = 0.5, y = 0.7, label = "2016~bold(u2640)",
size = 7, hjust = 0, parse = TRUE)
ggplot(df, aes(x, y)) + geom_point() +
annotate("text", x = 0.5, y = 0.7, label = "2016~bold(\u2640)",
size = 7, hjust = 0, parse = TRUE)
我也找到了this post,但不确定是否可以修改以下代码以在ggplot中使用?
plot(df)
text( locator(1), "\\VE", vfont=c("sans serif","bold"), xpd=TRUE) # Venus
最佳答案
@Axeman的评论帮助我找到了答案-我不知道您可以加载其他软件包来获取ggplot2的更多字体。谢谢!我使用以下代码:
install.packages("extrafont")
library(extrafont)
font_import() # Prepare for this to take several minutes
loadfonts(device = "win")
ggplot(df, aes(x, y)) + geom_point() +
theme_bw() +
annotate("text", x = 0.5, y = 0.7, label = "2016 ♀",
size = 7, hjust = 0, colour = "grey50", family = "Calibri", fontface = "bold")
