[英]scale of the y axis on ggplot for geom_line is bunched up
我正在使用對沖基金數據為金融計量經濟學課程的作業制作R降價文件。 我的作業定於星期二進行,但我在pdf_document中如何渲染圖形時遇到一些問題。
```{r Q4}
library(dplyr)
library(ggplot2)
library(scales)
hedgefunds.long <- hedgefunds.long %>% group_by(Strategy) %>% mutate(RET = (log(NAV)- lag(log(NAV))) * 100)
ggplot(hedgefunds.long) + geom_line(aes(x = date, y = RET)) + scale_y_continuous(breaks=pretty_breaks(n=6)) + facet_wrap(~ Strategy, ncol = 2)
我遇到的另一個問題是,在編織pdf文檔時會截斷位。 我想知道是否有一種方法可以確保下面圖片中的圖例在頂部和底部沒有被剪掉。
編輯:(更改了Corrplot一點,仍然沒有弄清楚調整大小)
corrplot(hedgefundcormatrix, method = "color",addgrid.col = "gray50", tl.cex = 0.8,tl.offset = 0.5, tl.col = "black")
放在每個數據集上

嘗試一下,看看是否有效...如果有效,將編輯帖子。 R-更改Corrplot的軸標簽的大小
我沒有可復制的數據要檢查,但在我看來,數字太大了,迫使您的數字聚集在一起。
facet_wrap(~ Strategy, ncol = 2)
一下您的圖形窗口大小,特別是Q4中的高度,還要在facet_wrap(~ Strategy, ncol = 2)
, facet_wrap(~ Strategy, ncol = 2)
考慮facet_wrap(~ Strategy, ncol = 2)
ncol > 2
; 以及Q8的寬度和高度
可以添加fig.width和fig.height```{r fig.width = x,fig.height = y}
{r Q4, fig.width=7, fig.height=10} # plot()
如果圖形大小不能解決問題,則可以設置邊距
# ggplot margins
gg + theme(plot.margin = unit(c(t,r,b,l), "cm")) # replace t,r,b,l with appropriate values
# plot margins
par(mar=c(b,l,t,r)) # replace b,l,t,r with appropriate values
plot()
