从R中的图中删除'y'标签

Question

有没有人知道如何从y轴提取'y',同时在下图中保留变量名称:

par(mar = c(5,7,4,2) +.01)
matrix <- matrix(rnorm(100) ,ncol = 2, nrow =6)
y <- 1:6
par(mar = c(5,7,4,2) +.01)
plot(matrix[,1], y, cex = .8, pch = 20, xlab = "Standardized Mean Differences", col = "darkblue",   main = "Balance Assessment", yaxt = "n")
points(matrix[,2], y, cex = .8, pch = 20, col ="cyan")
abline(v = 0, col = "gray50", lty =2)   
text(y =1:6, par("usr")[1], labels = c("Var1", "Var2", "Var3", "Var4", "Var5", "Var6"), pos = 2, xpd = TRUE, srt = 0, cex = .8, font = 1, col = "blue")

这很小,但它让我发疯.谢谢!

只是设置ylab=''删除它.
