R boxplot;将轴标签置于刻度线

标签: r boxplot par labeling

我使用以下代码绘制了一个数据帧(6个变量中有16700个障碍物):

labels <–c("X2137_Fe20","X2137_FeXS","vtc1_Fe20",
"vtc1_FeXS","VTC1c_Fe20","VTC1c_FeXS") #labels x axis
[1]col <- c("chartreuse3", "chocolate2", "chartreuse3", "chocolate2", 
"chartreuse3", "chocolate2") #colors

#Plot
boxplot(CVtable, 
    outline = FALSE, 
    ylim = c(-0.5,70), 
    main="CV Replicas",
    ylab="RSD(%)",
    range = 1.5,
    width = c(9,9,9,9,9,9),
    plot = TRUE,
    col = col,
    par (mar = c(5,4.5,5,0.5) + 0.1), 
    par(cex.lab=2), 
    par(cex.axis=1.7), 
    notch = TRUE,
    labels = labels)
dev.off()

This is the result

我喜欢这个盒子情节,但我想调整一些事情。我需要为x轴标签保留这个字体大小,但正如您所看到的那样,标签太大而且错过了部分标签。解决方案是将它们旋转45度,但我无法找到一个简单的代码插入我的脚本。

我尝试删除原始轴(axes=FALSE),然后按

设置新轴
boxplot(CVtable, 
    outline = FALSE, 
    ylim = c(0.5,70), 
    ylab="RSD(%)",
    range = 1.5,
    width = c(9,9,9,9,9,9),
    plot = TRUE,
    col = col,
    par (mar = c(5,4.5,5,0.5) + 0.1), 
    notch = TRUE,
    par(cex.lab=1.7),
    axes=FALSE)

axis(1, at = c(1,2,3,4,5,6), labels = F, tick = 2, line = NA,
 pos = -1, outer = F, font = 3, lty = "solid",
 lwd = 2, lwd.ticks = 3, col = NULL, col.ticks = NULL,
 hadj = NA, padj = 0)

axis(2, at = c(0,10,20,30,40,50,60,70) , labels = 
 c(0,10,20,30,40,50,60,70), tick = 2, line = NA,
 pos = 0.5, outer = FALSE, font = 1, lty = "solid",
 lwd = 2, lwd.ticks = 3, col = NULL, col.ticks = NULL,
 hadj = NA, padj = 0, par(cex.lab=1.5))

text(x=c(1,2,3,4,5,6), 
 y=par()$usr[3]-0.1*(par()$usr[4]-par()$usr[3]),
 labels=labels, srt=45, adj=1, xpd=TRUE, par(cex.lab=2))

这是输出:img2 好吧,我不知道如何将标签置于刻度标记下方,以及如何将x轴扩展到图形的原点(左侧)和最后一个方框的末尾(右侧)。此外,用于修复x轴标签字体大小的参数par(cex.lab=2)似乎不再适用于该字符串。

有什么好的建议吗?

我自己做了:

 #RSD
boxplot(CVtable[1:6], 
    outline = FALSE,
    ylim = c(0.5,70), 
    ylab="RSD(%)",
    range = 1.5,
    width = c(9,9,9,9,9,9),
    plot = TRUE,
    col = col,
    par (mar = c(7,4.5,1,0.5) + 0.1),  
    notch = TRUE,
    par(cex.lab=1.7),
    axes=FALSE)

axis(1, at = c(0.5,1,2,3,4,5,6,7), labels = F, tick = 2, line = NA,
 pos = -1, outer = F, font = 3, lty = "solid",
 lwd = 2, lwd.ticks = 3, col = NULL, col.ticks = NULL,
 hadj = NA, padj = 0)

axis(2, at = c(0,10,20,30,40,50,60,70) , labels = 
c(0,10,20,30,40,50,60,70), tick = 2, line = NA,
 pos = 0.5, outer = FALSE, font = 4, lty = "solid",
 lwd = 2, lwd.ticks = 3, col = NULL, col.ticks = NULL,
 hadj = NA, padj = 0, par(cex=1.4))

text(x=c(0.7,1.7,2.7,3.7,4.7,5.7), 
 y=par()$usr[3]-0.14*(par()$usr[4]-par()$usr[3]),
 labels=labels, srt=45, adj=0.6, xpd=TRUE, cex=1, font=2)

dev.off()

这是结果: enter image description here
