省略图R中的轴

Question

我在R中使用了以下代码来生成此图:

x  <- c(0.916, 0.815, 0.101, -0.029, -0.166, 0.949, 0.073, -0.054, 1.006)
y  <- c(3.91,  5.17,  1.08,   1.28,   1.01,  4.37,  3.97,   0.77,  4.52)
sd <- c(0.35,  2.26,  0.17,   0.08,   0.27,  0.49,  0.65,   0.12,  1.45)
windows()
plot(x,y, ylim=c(0, 8), xlim=c(-0.4, 1.2), pch=19, cex.axis=0.8, 
     cex.lab=0.9, xlab="Male/Female expression ratio (log)", 
     ylab="Z/W expression ratio in females", las=1)
for (i in 1:9) {
  up  <- y[i] + sd[i]
  low <- y[i] - sd[i]
  segments(x[i],      low, x[i],      up)
  segments(x[i]-0.02, up,  x[i]+0.02, up)
  segments(x[i]-0.02, low, x[i]+0.02, low)
}

我的问题是我如何摆脱两个顶轴和右轴并且只保留左下轴？

Answer 1

如果您想保持盒状外观而不是"自由浮动"轴,bty ="l"请在plot命令中添加(小写L).

导致:

plot(x, y, ylim=c(0, 8), xlim=c(-0.4, 1.2), pch=19, cex.axis=0.8, 
     cex.lab=0.9, xlab="Male/Female expression ratio (log)", 
     ylab="Z/W expression ratio in females", las=1, bty = "l")

这只会移除上框架和右框架杆.也可以看看?par

编辑:
看看您的图表和您的计算似乎,您想要为特定组绘制平均值,然后还显示一些标准偏差.在这种情况下,我建议boxplot()您查看使用原始数据为您执行此操作的命令.看到?boxplot
