Values of a vector without variable names-CodePudding

In R you can do this to retrieve the values of the elements of an numeric vector where time > 20

time <- c(17, 16, 20, 24, 22, 15, 21, 15, 17, 22)
time[time>20]

But how could I do this without first assigning the vector? Is there something like:

c(17, 16, 20, 24, 22, 15, 21, 15, 17, 22)[%>20]

CodePudding user response：

Use a pipe operator (|>) from base R

c(17, 16, 20, 24, 22, 15, 21, 15, 17, 22) |> 
     {\(x) subset(x, x > 20)}()

-output

[1] 24 22 21 22

Or with dplyr/magrittr %>%

c(17, 16, 20, 24, 22, 15, 21, 15, 17, 22) %>% 
  .[. > 20]
[1] 24 22 21 22
