R，改变轴刻度线和刻度线标签之间的距离

Question

In the following example, I plot a custom tick mark at .95 (edited to make labels horizontal as per Thomas' suggestion):

d = matrix(runif(40), ncol=4)
colnames(d) = c('a','b','c','d')

barplot(
    d,
    beside=T, 
    col=c('#CD4E3C', '#816DC3','#569340', '#A87929'), 
    ylim=c(0,1), 
    cex.axis=.80,
    main= 'Title',
    las=1

)

abline(h= 1:10/10, col = 'lightgray', lty=3)
axis(side=2, at=c(.95), cex.axis=.75, tck=-.01, las=1)
abline(h= .95, col = '#000000', lty=3)

Which gives:

My custom label is too close to the regular label (which I also need), and I'd like to bring the label closer to the tick mark. I looked through

help(par) 

How might a bring that label closer to the axis?

EDIT: Making the tick mark labels horizontal helped, but I'd still like to indent the label for .95 to reflect the shortened tick mark.

Answer 1

Quick solution is to put las=2 in both your barplot() and axis() calls to make labels horizontal and they'll be clearer.

EDIT: Use mtext instead of axis :

mtext("0.95",2,.5,at=.95,las=2,cex=.75)
