我正在尝试设置我需要的计划,但出现以下错误:
no_cores <- availableCores() - 2
plan(multisession, workers = no_cores, lazy = T, gc = T)
错误是:
Error in MultisessionFuture(expr = expr, envir = envir, substitute = FALSE, :
argument "expr" is missing, with no default
或者:
plan(multisession, workers = no_cores, lazy = T, gc = T)
Error in tweak.future(function (expr, envir = parent.frame(), substitute = TRUE, :
Future argument 'lazy' must not be tweaked / set via plan()
请告知如何设置/ 计划的workers
,lazy
和gc
其他参数。multisession
multicore
