我正在尝试使用 R 中的 reshape 函数在表中排列我的数据时间点。我用来分割它的变量是数字的，但是当 reshape 排列表格时，它错误地放置了 2,0.5,4,6,8,0,24...168，而不是 0.0 , 0.5 , 2.0 , 4.0 , 6.0 、8.0、24.0、48.0...168.0
非常感谢任何帮助。 这是我的数据：

我正在做这个：
G2r = reshape(G2, direction = "wide",
idvar = c("Animal","Sex"),
times = Time,
timevar = "Time"
)
我明白了：
> head(G2r)

我尝试对时间进行排序并将其设置为 times = sort(unique(G2$Time))，但它不起作用。 我还尝试了 na.omit(Time) 和 na.omit(Sugar) 以防 NA 产生问题。但也没有成功。
如果您对进入
reshape()G2[order(G2$Animal, G2$Sex, G2$Time), ]G2r = reshape(G2[order(G2$Animal, G2$Sex, G2$Time), ], direction = "wide",
idvar = c("Animal","Sex"),
times = Time,
timevar = "Time"
)
