R 我有置信区间向量，但如何将这些值添加到条形图中？

我有3个估计向量：

est1 <- c(0.0930, NA, NA, 0.0157, 0.0187, 0.0137, NA, NA, 0.0426, NA, NA, NA, 0.0129, 0.0075, 0.0131, 0.0194, 0.0129, 0.0435, 0.0338, 0.0276, 0.0382, -0.0070)
est2 <- c(0.0094, NA, NA, 0.0081, 0.0060, 0.0066, NA, NA, 0.0060, NA, NA, NA, 0.0067, 0.0061, 0.0043, 0.0067, 0.0060, 0.0092, 0.0101, 0.0118, 0.0133, -0.0011)
est3 <- c(0.0045, 0.0064, 0.0053, 0.0060, 0.0057, 0.0061, 0.0081, 0.0044, 0.0074, 0.0077,     0.0059, 0.0086, 0.0059, 0.0040, 0.0068, 0.0059, 0.0056, NA, NA, 0.0130, 0.0130, 0.0071)

对于散点图，我通常使用函数箭头（）添加置信区间，设置x0=x1：

arrows(x0, y0, x1, y1, angle = 90, code = 3, lwd = 3, length = 0.1, col = 7)

但我不知道如何将其应用于条形图的结构。我需要得到x轴的位置，并考虑这组条之间的间距。 有人能帮点忙吗？

谢谢!
