使用paste0的中缀（％＆gt;％）运算符

Question

所以我想在%>% way中堆叠字符串。说，我有一个字符向量

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

和一个字符串：

phrase <- "Name is "

通常的方法是paste0：

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

有没有办法用%>%执行此操作？我能够以相反的顺序连接这些：

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

Answer 1

您可以尝试：

phrase %>% paste0(names)

哪个给出了

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

或者，您可以使用.：

访问LHS

names %>% paste0(phrase, .)

还会返回：

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