我无法替换表中的某些值。我不确定grepl函数为何适用于某些单元格，但不适用于某些单元格。
我有下表：
table = structure(list(V1 = c("Report", "Report", "Report",
"Report", "Report", "Report",
"Report", "Report", "Report",
"Report", "Report", "Report",
"Report", "Report", "Report",
"Report", "Report", "Report",
"Report"), V2 = c("Deanna", "Deanna", "Deanna",
"Phil", "Phil", "Phil", "Phil", "Mark", "Mark", "Mark",
"Mark", "Stacey+Phil", "Stacey+Phil", "Stacey+Phil", "Stacey+Phil",
"Total", "Total", "Total", "Total"), RiskType = c("Sales",
"Sales", "Sales", "Sales", "Sales", "Sales", "Sales",
"Sales", "Sales", "Sales", "Sales", "Sales", "Sales",
"Sales", "Sales", "Sales", "Sales", "Sales", "Sales"
), CurrencyResults = c("AUD", "NZD", "Total", "AUD", "NZD", "Total", "USD",
"AUD", "NZD", "Total", "USD", "AUD", "NZD", "Total", "USD", "AUD",
"NZD", "Total", "USD"), Negative = c(-51620.213555, 771045.326333,
-771144.54622, 10556202.43205, 055.2236103, 117135173.415,

-4267021.367)), class = "data.frame", row.names = c(NA, -19L
))
如果我使用
table %>% mutate(V2 = replace(V2, str_detect(V2, "^Mark$"), "Terry"))
它运作良好（并用特里代替了马克斯。
但是如果我尝试同样的事情，
table %>% mutate(V2 = replace(V2, str_detect(V2, "^Stacey+Phil$"), "Terry"))
它不起作用。
我已经做了一些搜索，我认为它可能与正则表达式有关，但是我没有找到解决方法。我正在寻找一种仅用短语“ Terry”代替“ Stacey + Phil”的方法。任何帮助将不胜感激。
