这是我的数据
decay<- c("None", "None", "11, 55, 64", "None", "54, 66, 74", "47, 74, 55")
我想将所有数字列表转换为"Yes"。我该怎么办？

可能您需要：
decay[grepl("\\d", decay)] <- "Yes"
decay
#[1] "None" "None" "Yes" "None" "Yes" "Yes"

尝试使用gsub：
> gsub(".*\\d.*","Yes",decay)
[1] "None" "None" "Yes" "None" "Yes" "Yes"

也许可以尝试相反的选择，任何不是“无”的内容都是“是”：
decay[ decay != "None" ] <- "Yes"
decay
# [1] "None" "None" "Yes" "None" "Yes" "Yes"
