帶粘貼的中綴（％>％）運算符

Question

所以我想以%>% way堆疊字符串。 說，我有一個角色向量

names <- c("Alice","Bob","Charles")

和一個字符串：

phrase <- "Name is "

通常的方法是paste0 ：

> paste0(phrase, names)
[1] "Name is Alice"   "Name is Bob"     "Name is Charles"

有沒有辦法用%>%做到這一點？ 我只能以相反的順序連接它們：

> names %>% paste0(phrase)
[1] "AliceName is "   "BobName is "     "CharlesName is "

Answer 1

你可以試試：

phrase %>% paste0(names)

這使

[1] "Name is Alice"   "Name is Bob"     "Name is Charles"

或者，您可以使用訪問LHS . ：

names %>% paste0(phrase, .)

還會返回：

[1] "Name is Alice"   "Name is Bob"     "Name is Charles"
