I need to make a call to an API separately for each row of my tibble. How can I introduce a small lag between each call? I need to do this because the API I am using limits the allowable number of requests per second.
How can I modify the following (psuedo) code to accomplish this? The code creates a list column called authors, which is populated by the result from the (made up) get_API_value API call.
library(tidyverse)
data %>%
rowwise() %>%
mutate(authors = list(get_API_value(arg1 = val1, arg2 = val2)))
In other words, how can I make the above code incorporate a lag (such as Sys.sleep(1))?
You could add a Sys.sleep() inside of curly braces, separated by a semi-colon
library(tidyverse)
data %>%
rowwise() %>%
mutate(authors = {Sys.sleep(1); list(get_API_value(arg1 = val1, arg2 = val2))})
