2つの異なるdfからプロットを作成したい

私のコード：

ggplot() +
  geom_boxplot(data=df.temp1, aes(x = sample2, y=delta_rn)) +
  theme_bw() +
  theme(plot.title = element_text(hjust = 0.5), axis.title = element_text(size=20),axis.text=element_text(size=15),
        axis.text.x=element_text(angle = -40, hjust = 0))+
  geom_boxplot(data=df.temp2, aes(x = 'rn',y=delta_rn))

df1：

structure(list(sample2 = c("p10_065", "p10_065", "p10_065", "p10_065", 
"p10_065", "p10_065", "p10_065", "p10_065", "p10_065", "p39_080",

43L, 44L, 45L, 46L, 47L, 48L, 49L, 50L))

およびdf2：

structure(list(sample2 = c("p10_065", "p39_080", "s36_068", "s32_066", 
"s43_078", "s29_083", "p1_065", "p2_080", "s21_077", "p41_072", 
"s22_066"), delta_rn = c(5121066L, 6585801L, 2955395L, 0L, 4636924L, 
4271671L, 2699432L, 1884355L, 4851650L, 1846467L, 1588973L)), class = "data.frame", row.names = c(101L, 
71L, 11L, 21L, 1L, 31L, 91L, 81L, 51L, 61L, 41L))

そしてここに私のプロットがあります：

問題は、「rn」ラベルが中央にあり、このx軸をカスタマイズできないことです。アルファベット順に並べ替えていますが、2番目のdfから取得したこのラベルを、プロットの左端または右端に配置したいと思います。わかりやすくするために、ラベルをdfで注文したいと思います...

を作成しlabels、axis使用の手動注釈を行うことができますscale_x_discrete(labels= xlabs)：

xlabs <- c("rn", levels(factor(df1$sample2)))

ggplot() +
  geom_boxplot(data=df1, aes(x = sample2, y=delta_rn)) +
  theme_bw()+
  theme(plot.title = element_text(hjust = 0.5), axis.title = element_text(size=20),axis.text=element_text(size=15),
        axis.text.x=element_text(angle = -40, hjust = 0))+
  geom_boxplot(data=df2, aes(x = '',y=delta_rn)) +  scale_x_discrete(labels= xlabs)
