Question

我很难生成使用xtable包的LaTex格式表。我试图做三件事：

没有第一列只是编号的行。
让列为固定宽度。
使用longtable环境，因为它是一个大表。

以下是我尝试导出为LaTex表格的对象：

structure(list(Name = structure(c(23L, 20L, 21L, 22L, 14L, 11L, 
12L, 13L, 15L, 5L, 4L, 3L, 2L, 6L, 7L, 8L, 9L, 10L, 17L, 18L, 
19L, 24L, 25L, 28L, 29L, 27L, 26L, 16L, 1L), .Label = c("age.cat", 
"ALQ101", "BMXBMI", "BMXHT", "BMXWT", "CBD070", "CBD090", "CBD110",

10L, 1L, 9L, 18L, 7L, 8L, 17L, 3L, 29L, 12L, 6L, 11L, 20L, 24L, 
23L, 22L, 21L, 19L, 14L, 13L, 27L, 28L, 15L, 16L, 26L, 5L, 4L,

"Used Tobacco/Nicotine in Last 5 Days", "Weight (kg)"), class = "factor"), 
    Values = structure(c(1L, 8L, 20L, 10L, 26L, 25L, 7L, 9L, 
    2L, 21L, 23L, 19L, 26L, 17L, 13L, 15L, 16L, 18L, 14L, 6L, 
    5L, 26L, 26L, 12L, 11L, 22L, 24L, 3L, 4L), .Label = c("", 
    "0-4999, 5000-9999, 10000-14999, 15000-19999, 20000-24999, 25000-34999, 35000-44999, 45000-54999, 55000-64999, 65000-74999, Over 20000, Under 20000, 75000-99999, 100000 and over",

    "Range of values 82 – 204.5", "Underweight, Normal, Overweight, Obese", 
    "United States, Other", "Yes, No"), class = "factor")), .Names = c("Name", 
"Description", "Values"), class = "data.frame", row.names = c(NA, 
-29L))

如果我只使用命令xtable(df)，我会得到一个四列表，其中第一列只是对行进行编号。我怎能不这样做？

我知道xtable有一个align参数，但是当我使用时（从this solution复制）

xtable(df, align=c("l","l","l","p\{5cm\}"))

我收到错误：

\{ is an urecognized escape in character string starting ""p\{".

我尝试过使用双反斜杠，但这也不起作用。

一旦我解决了前两个问题，我相信命令只是print(df, tabular.environment = "longtable")，对吗？

Answer 1

要修复错误，请在align字符串中使用两个反斜杠，如下所示：

xtable(df, align=c("l", "l", "l", "p\\{5cm\\}"))

您的数据框没有行名称，默认情况下在打印xtable对象时包含这些行名称，因此它使用行号。为避免这种情况，请在include.rownames=FALSE函数中使用print()。

print(xtable(df, align=c("l", "l", "l", "p\\{5cm\\}")),
      include.rownames=FALSE,
      tabular.environment="longtable")

xtable：使用align参数添加了额外的列和错误
