我需要按升序在 R 内按升序排序，并分别对其他列进行排序。我尝试首先将其分配给名为table的变量：
table <- read.csv("assessment.csv")
之后，当我尝试将该表存储到名为sortedTable的新表中时：
sortedTable <- table[order(time),]
我收到此错误：
顺序错误（时间）：参数1不是向量
我设法做了一次，我不知道怎么做，但即便如此，桌子已经排序但是在某个地方，连续14:00，这很奇怪。如何正确对表格进行排序？

从左到右要order data.frame的列，请使用do.call。例如：
mtcars[do.call("order",mtcars),]
mpg cyl disp hp drat wt qsec vs am gear carb
Lincoln Continental 10.4 8 460.0 215 3.00 5.424 17.82 0 0 3 4
Cadillac Fleetwood 10.4 8 472.0 205 2.93 5.250 17.98 0 0 3 4
Camaro Z28 13.3 8 350.0 245 3.73 3.840 15.41 0 0 3 4
Duster 360 14.3 8 360.0 245 3.21 3.570 15.84 0 0 3 4
Chrysler Imperial 14.7 8 440.0 230 3.23 5.345 17.42 0 0 3 4
Maserati Bora 15.0 8 301.0 335 3.54 3.570 14.60 0 1 5 8

如果table很大（很多行），使用数据表可能会更快：
library(data.table)
dt <- data.table(table)
sorted <- setkeyv(dt,colnames(dt))
