我有一个名为示例的数据帧，其中出现了一些语义特征：
> str(examples)
Classes ‘spec_tbl_df’, ‘tbl_df’, ‘tbl’ and 'data.frame': 50 obs. of 12 variables:
$ filename : chr "Text01" "Text02" "Text03" "Text04" ...
$ Control : num 1 3 0 0 0 6 0 1 0 1 ...
$ Economic : num 1 3 0 0 0 0 1 0 1 2 ...
$ ExternalVoices: num 1 2 1 1 1 2 1 4 0 1 ...
$ JobsSkills : num 0 0 0 0 0 2 0 3 0 0 ...
$ LegalStatus : num 0 3 4 0 5 0 1 0 4 0 ...
$ Modals : num 4 6 1 5 4 4 2 6 2 2 ...
$ Orign : num 2 6 8 6 3 5 3 3 2 6 ...
$ Sanctions : num 1 3 0 3 0 3 2 1 1 0 ...
$ Subjectivisms : num 2 3 4 4 3 2 1 1 2 4 ...
$ Verbs : num 3 7 3 11 6 2 7 7 4 5 ...
$ LineTotal : num 130 274 258 419 268 210 379 244 172 199 ...

head(examples)
A tibble: 6 x 12

6 Text06 6 0 2 2 0 4 5 3 2 2 210
我需要应用一个公式，将每个单元格的值乘以1000，然后除以行的总和，即递归地除以列"LineTotal"：
(cellx1000(/LineTotal
LineTotal每行的变化。
我甚至想不出一种方法来完成它。任何帮助都会很棒！
谢谢！

谢谢！
这里有一个使用tidyverse的可能解决方案：
library(tidyverse)
examples %>%
mutate_at(
vars(-matches("filename|LineTotal")),
~ .x * 1000 / LineTotal
)
我想这就是您想要的
1( 定义行总的列号
colname_tot = which(colnames(examples) == "LineTotal") -1
2( 使用apply在每行上执行此操作
examples = rbind(examples[, 1], as.data.frame(t(apply(examples[, -1], 1, function(x) {x = x*1000/x[colname_tot]})))
希望这能有所帮助，
我认为这就是您想要的(其中example是您的数据帧(
example[,2:ncol(example)] <- lapply(2:ncol(example), function(X) example[,X]*1000/sum(example[,X]))
编辑：一个问题是数据帧的第一列中有字符。这段新代码使用了您提供的示例数据。
