1d:T4fe,# Reset a finished, failed, canceled, or interrupted future to a lazy future A future that has successfully completed, canceled , interrupted, or has failed due to an error, can be relaunched after resetting it. ```r reset(x, ...) ``` ## Arguments - `x`: A Future. - ``: Not used. ## Returns `reset()` returns a lazy, vanilla Future that can be relaunched. Resetting a running future results in a FutureError . ## Details A lazy, vanilla Future can be reused in another R session. For instance, if we do: ``` library(future) a <- 2 f <- future(42 * a, lazy = TRUE) saveRDS(f, "myfuture.rds") ``` Then we can read and evaluate the future in another R session using: ``` library(future) f <- readRDS("myfuture.rds") v <- value(f) print(v) #> [1] 84 ``` ## Examples ```r ## Like mean(), but fails 90% of the time shaky_mean <- function(x) { if (as.double(Sys.time()) %% 1 < 0.90) stop("boom") mean(x) } x <- rnorm(100) ## Calculate the mean of 'x' with a risk of failing randomly f <- future({ shaky_mean(x) }) ## Relaunch until success repeat({ v <- tryCatch(value(f), error = identity) if (!inherits(v, "error")) break message("Resetting failed future, and retry in 0.1 seconds") f <- reset(f) Sys.sleep(0.1) }) cat("mean:", v, "\n") ```1e:T49a,M7.49933 0.25C3.49635 0.25 0.25 3.49593 0.25 7.50024C0.25 10.703 2.32715 13.4206 5.2081 14.3797C5.57084 14.446 5.70302 14.2222 5.70302 14.0299C5.70302 13.8576 5.69679 13.4019 5.69323 12.797C3.67661 13.235 3.25112 11.825 3.25112 11.825C2.92132 10.9874 2.44599 10.7644 2.44599 10.7644C1.78773 10.3149 2.49584 10.3238 2.49584 10.3238C3.22353 10.375 3.60629 11.0711 3.60629 11.0711C4.25298 12.1788 5.30335 11.8588 5.71638 11.6732C5.78225 11.205 5.96962 10.8854 6.17658 10.7043C4.56675 10.5209 2.87415 9.89918 2.87415 7.12104C2.87415 6.32925 3.15677 5.68257 3.62053 5.17563C3.54576 4.99226 3.29697 4.25521 3.69174 3.25691C3.69174 3.25691 4.30015 3.06196 5.68522 3.99973C6.26337 3.83906 6.8838 3.75895 7.50022 3.75583C8.1162 3.75895 8.73619 3.83906 9.31523 3.9
