我成功（似乎）正在读取名为abalone的csv文件，该文件有9个变量。但我似乎无法对它们做任何事情，例如情节：
abalone <- read_csv("~/Abalone/abalone/abalone.csv")
Parsed with column specification:
cols(
Sex = col_character(),
Length = col_double(),
Diameter = col_double(),
Height = col_double(),
`Whole weight` = col_double(),
`Shucked weight` = col_double(),
`Viscera weight` = col_double(),
`Shell weight` = col_double(),
Rings = col_integer()
)
Diameter
Error: object 'Diameter' not found
Rings
Error: object 'Rings' not found
summary(abalone)

这就是我正在尝试的：
plot(Length ~ Sex, data=abalone)
错误：
Error in plot.window(...) : need finite 'xlim' values
另外：警告信息：
1: In xy.coords(x, y, xlabel, ylabel, log) : NAs introduced by coercion
2: In min(x) : no non-missing arguments to min; returning Inf
3: In max(x) : no non-missing arguments to max; returning -Inf
