R中的旋转轴标签

Question

我需要帮助旋转下图的轴标签。按照目前的设置，最终的label因为有限space没有显示。我理解文本，srt 代码用于此目的但无法旋转当前显示的标签（新数字反而出现在图表本身）：

Xmin=0-2
Xmax=0+2
plot(x, y, type='n', xlab='x-axis',                               
    col.axis="grey", cex.axis=0.7, tck=-.02, xaxt="n")
x <- c(-2,2)
y <- c(-1,1)
plot(x, y, type='n', xlab='x-axis', col.axis="grey", cex.axis=0.7,       
tck=-.02, xaxt="n")
abline(a=-.6, b=-.2, lty=1, pch=15, lwd=1, col='black') 
abline(a=.03, b=.2, lty=5, pch=15, lwd=1, col='black')
axis(1, at=c(-2, -1, 1.9, 2), labels=c("8.07", "8.976", "11.7",          
"11.9"), tck=.01, cex.axis=0.9, srt=45, col.ticks = "grey")

Answer 1

尝试添加 las=2

axis(1, at=c(-2, -1, 1.9, 2), labels=c("8.07", "8.976", "11.7",          
               "11.9"), tck=.01, cex.axis=0.9, srt=45, col.ticks = "grey", las=2)
