Answer 1

尝试这个

A4 <- within(A4, resize <- factor(Size > 1000, c("S", "L")))

Answer 2

cut正是这样做的。

A4$resize <- cut(A4$Size, breaks = c(-Inf, 1000, Inf), labels = c("S", "L"))

Answer 3

We can use findInterval

A4$resize <- with(A4, c('S', 'L')[findInterval(Size, 1000)])

---

Or using case_when

library(dplyr)
A4 %>%
   mutate(resize = case_when(Size > 1000 ~ "S", TRUE ~ "L"))
