如何在以下图表中将y轴标签格式更改为常规（xxx.xxx）而非科学？

df <- read.table(textConnection("
    ypogr_act  amount           cumSum

library(lattice)
library(zoo)
x <- zoo(df[2:3], df$ypogr_act)

win.graph(12,8)

print( xyplot(x, lwd=2,xlab='Μήνας',
              col=c(rgb(127, 201, 127, max = 255),rgb(56, 108, 176, max = 255)),
              scales = list(y=list(rot = 0,abbreviate=FALSE)) ))
trellis.focus("panel", 1, 1, highlight = F)
panel.grid(h = -1, v = 0, col = "grey", lty = 3)
trellis.unfocus()

编辑是一个更简单的解决方案：只需设置options(scipen=10)然后运行您的代码即可。要暂时更改选项，您可以执行以下操作：

oscipen <- options(scipen=10)
## <Your plotting code>
options(oscipen)

可能有一个更简单的解决方案，但这就是我要做的事情：

## Write a customized axis annotation function 
## (Uses latticeExtra::xscale.components.log() et al. as templates.)
yscale.components.custom <- function (lim, logsc = FALSE, ...) {
    ans <- yscale.components.default(lim, logsc = logsc, ...)
    ans$left$labels$labels <- format(ans$left$labels$at, digits=3, scientific=10)
    ans
}

## Point to the customized function via xyplot's 'yscale.components=' argument
xyplot(x, lwd=2,xlab='???a?',
       col=c(rgb(127, 201, 127, max = 255),rgb(56, 108, 176, max = 255)),
       scales = list(y=list(rot = 0,abbreviate=FALSE)),
       yscale.components = yscale.components.custom)
