用R绘制置信区间数据

Question

我想按年计算平均CPUE并添加已计算的CI。

根据拖网调查数据的方法计算CI，因此我认为我不能使用R中可用的任何CI绘图功能。我真的很感激任何帮助。

我一直试图通过我在网上找到的示例来解决这个问题，但CI并未在我的数据点上绘制。我在Windows 8上有R版本3.1.0。这是我的代码。

dput(fall)

structure(list(Year = structure(1:7, .Label = c("2007", "2008", 
"2009", "2010", "2011", "2012", "2013", "2014"), class = "factor"), 
    Season = structure(c(1L, 1L, 1L, 1L, 1L, 1L, 1L), .Label = c("Fall", 
    "Spring"), class = "factor"), CPUE = c(2.67597320766895, 
    1.13720423803133, 3.33880765324431, 0.806172684858967, 1.4489759307485,

    0.362059980159386), lower = c(2.07563668109912, 1.01926446969017, 
    2.61363856286983, 0.584320068914576, 1.36908295705723, 9.92183627713643, 
    4.30084507885747), upper = c(3.27630973423878, 1.2551440063725, 
    4.06397674361879, 1.02802530080336, 1.52886890443977, 11.1767619128722, 
    4.7487357144182)), .Names = c("Year", "Season", "CPUE", "Variance", 
"SD", "Number", "CV", "lower", "upper"), row.names = c(NA, 7L
), class = "data.frame")

我的情节尝试是：

plot(fall$CPUE, type='n', xlab="Year", ylab='Mean CPUE', axes=F)
axis(1, at=1:8, labels=levels(fall$Year))
axis(2)
box()
lines(fall$Year, fall$CPUE, col=1)
points(fall$Year, fall$CPUE, col=1, pch=16)
arrows(y0 = fall$lower, y1 = fall$upper, x0 = fall$CPUE, x1 = fall$CPUE, 
length=0.1, code = 3, col = 4, angle = 90)
