条件付きサイズと顔geom_text_repel

Question

かなり大きな散布図に取り組んでおり、重複するラベルを避ける方法としてggrepelを使用しています。しかし、私はいくつかのデータポイントを区別する必要があり、その考え方はsizeとfaceに依存することも考えられます。

私は、データセットを投稿：

), row.names = c(NA, -95L), class = c("tbl_df", "tbl", "data.frame" 
)) 

は現在、私はプロットを指定するには、以下のコードを使用します。

ggplot(dat, aes(horizontal, vertical)) + 
    geom_point(data=subset(dat, dat$issue=="issue"), 
      color = 'black', size=5, shape=3) + 
    geom_point(data=subset(dat, dat$issue=="party"), 
      color = 'black', aes(shape=year), size=2) + 
    scale_shape_manual(values=c(19,15,17,10,11,12,18,13,14,7,8,9,0,5,1))+ 
    geom_text_repel(data=subset(dat, dat$issue=="party"), 
        aes(horizontal, vertical, label = object_n), size=2.5, family = "Franklin Gothic Demi") + 
    geom_text_repel(data=subset(dat, dat$issue=="issue"), 
        aes(horizontal, vertical, label = object_n), size=3.2, 
        family = "Franklin Gothic Demi", 
        fontface = 'bold') + 
    theme_classic(base_size = 16) + 
    theme(axis.line=element_blank(),axis.text.x=element_blank(), 
     axis.text.y=element_blank(),axis.ticks=element_blank(), 
     axis.title.x=element_blank(), 
     axis.title.y=element_blank(),legend.position="none", 
     panel.background=element_blank(),panel.border=element_blank(),panel.grid.major=element_blank(), 
     panel.grid.minor=element_blank(),plot.background=element_blank()) 

これは正常に動作し、次のプロット生成します。

を

しかし、私が指定したのは、です2つのサブセットのでは、ラベルが重なり合って、このジオムを使用する点が殺されます。 geom_text_repelを条件付きsizeとfaceで設定する方法はありますか？私はwhat is suggested hereに似た何かを試してみましたが、私は継続的にエラーに遭遇：

ff <- function(issue){ifelse(dat$issue=="issue",3.2,2.5)} 

mds <- ggplot(dat, aes(horizontal, vertical)) + 
    geom_point(data=subset(dat, dat$issue=="issue"), 
      color = 'black', size=5, shape=3) + 
    geom_point(data=subset(dat, dat$issue=="party"), 
      color = 'black', aes(shape=year), size=2) + 
    scale_shape_manual(values=c(19,15,17,10,11,12,18,13,14,7,8,9,0,5,1))+ 
    geom_text_repel(dat,aes(horizontal, vertical, label = object_n, size = factor(issue)), 
        family = "Franklin Gothic Demi") + scale_size_manual(values=ff(issue)) + 
    theme_classic(base_size = 16) + 
    theme(axis.line=element_blank(),axis.text.x=element_blank(), 
     axis.text.y=element_blank(),axis.ticks=element_blank(), 
     axis.title.x=element_blank(), 
     axis.title.y=element_blank(),legend.position="none", 
     panel.background=element_blank(),panel.border=element_blank(),panel.grid.major=element_blank(), 
     panel.grid.minor=element_blank(),plot.background=element_blank()) 
mds 

： ggplot2は、私が試してみました何これは、例えばある

unevalクラスのデータに対処する方法を知りません

何か助けていただければ幸いです！

Answer 1

これは役に立ちますか？ただ、fontfaceのための新しい変数を作成し、既存のテキストのサイズを模倣するscale_size_manualを使用して：

library(tidyverse) 
library(ggrepel) 

# this is a nice helper fxn if you are using the same theme a lot :) 
theme_set(theme_classic(base_size = 16) + 
        theme(axis.line=element_blank(),axis.text.x=element_blank(), 
         axis.text.y=element_blank(),axis.ticks=element_blank(), 
         axis.title.x=element_blank(), 
         axis.title.y=element_blank(),legend.position="none", 
         panel.background=element_blank(),panel.border=element_blank(),panel.grid.major=element_blank(), 
         panel.grid.minor=element_blank(),plot.background=element_blank())) 

dat$ff <- ifelse(dat$issue == "issue", "bold", "plain") 

ggplot(dat, aes(horizontal, vertical)) + 
    geom_point(data=subset(dat, dat$issue=="issue"), 
       color = 'black', size=5, shape=3) + 
    geom_point(data=subset(dat, dat$issue=="party"), 
       color = 'black', aes(shape=year), size=2) + 
    scale_shape_manual(values=c(19,15,17,10,11,12,18,13,14,7,8,9,0,5,1)) + 
    geom_text_repel(aes(label = object_n, size = issue, fontface = ff)) + 
    scale_size_manual(values = c(3.5, 2.5)) 

は、テキストの最終サイズは、あなたが記録するために使用しているグラフィックスデバイスのサイズによって部分的に規定されようとしていることを忘れないでください。これは、800 pxと511ピクセルの高さの幅を持つPNGなどのようになります。

Answer 2

は、このコードを見てください：

ggplot(dat, aes(horizontal, vertical)) + 
    geom_point(data=subset(dat, dat$issue=="issue"), 
      color = 'black', size=5, shape=3) + 
    geom_point(data=subset(dat, dat$issue=="party"), 
      color = 'black', aes(shape=year), size=2) + 
    scale_shape_manual(values=c(19,15,17,10,11,12,18,13,14,7,8,9,0,5,1))+ 
    geom_text_repel(data=dat,aes(horizontal, vertical, label = object_n, size = issue == "issue"), 
        family = "Franklin Gothic Demi") + scale_size_manual(values=c(1,5)) + 
    theme_classic(base_size = 16) + 
    theme(axis.line=element_blank(),axis.text.x=element_blank(), 
     axis.text.y=element_blank(),axis.ticks=element_blank(), 
     axis.title.x=element_blank(), 
     axis.title.y=element_blank(),legend.position="none", 
     panel.background=element_blank(),panel.border=element_blank(),panel.grid.major=element_blank(), 
     panel.grid.minor=element_blank(),plot.background=element_blank()) 
mds 

あなたが本当に機能を必要としない、それはあなたが大きさらに

エラーを選択することsize = issue == "issue"、さらにscale_size_manual(values=c(1,5))を使用する場合は十分にある

error: ggplot2 doesn't know how to deal with data of class uneval

あなたが欠けていた原因が data=
