我有一个包含不同列的数据集。看起来像那样
df <- data.frame(PatientID = c("0002" ,"0004", "0005", "0006" ,"0009" ,"0010" ,"0018", "0019" ,"0020" ,"0027", "0039" ,"0041" ,"0042", "0043" ,"0044" ,"0045", "0046", "0047" ,"0048" ,"0049", "0055"),

above threshold 的额外列。 , 那将是 TRUE/FALSE基于以下条件:成为
TRUE ，患者需要在 6 列(A、B、C、D、E 或 G)中的任意 3 列中具有高于阈值的值，阈值是:否则是
FALSE基本上 3 个或更多列需要为 TRUE，最后一列为 TRUE。输出看起来像这样(高于阈值 == TRUE 被涂成绿色):
我怎么能设置这个？ - 我希望这很清楚，但如果不是，请询问!
非常感谢!
最佳答案
我们创建了一个名为 list (或命名 vector )，遍历除“PatientID”以外的列，提取 list具有列名 ( cur_column() ) 的元素，通过添加后缀 _new 创建一个新的逻辑列在 .names ，然后使用 rowSums检查每行的 TRUE 数量是否大于或等于 3 以创建“above_threshold”
library(dplyr)
lst1 <- list(A = 990, B = 990, C = 1000, D = 1000, E = 1005, G = 1005)
df %>%
mutate(across(A:G, ~ . > lst1[[cur_column()]],
.names = '{.col}_new'),
above_threshold = rowSums(select(cur_data(), ends_with('new')),
na.rm = TRUE) >=3) %>%
select(names(df), above_threshold)
PatientID A B C D E G above_threshold
