如何使用轴（）在y轴上水平书写标签

Question

目的

在axis()之后用barplot()水平标记标签。

代码

par(mai=c(2, 1, 1, 1), lwd=2)
barplot(as.numeric(c(2, 4, 1, 6)), col = c("lightblue"), main="Bar plot",
        names.arg=c("This is bar 1...1","This is bar 1...2",
                    "This is bar 1...3","This is bar 1...4"),
        xpd=TRUE, las=2, lwd=2, axes=FALSE, axis.lty=1,
        cex.axis=1, cex.names=1, cex.main=1, ylim=c(-5,8.5),xlim=c(-6,5))
axis(2, -3:9)

你快到了！您可以为x轴设置las，但不为y设置（单独调用）。这里：

par(mai=c(2, 1, 1, 1), lwd=2)
barplot(as.numeric(c(2, 4, 1, 6)), col = c("lightblue"), main="Bar plot",
        names.arg=c("This is bar 1...1","This is bar 1...2",
                    "This is bar 1...3","This is bar 1...4"),
        xpd=TRUE, las=2, lwd=2, axes=FALSE, axis.lty=1,
        cex.axis=1, cex.names=1, cex.main=1, ylim=c(-5, 8.5), xlim=c(-6, 5))
axis(2, -3:9, las=2)
