how can I solve this (> library(SimDesign) Error: package or namespace load failed for ‘SimDesign’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there is no package called ‘future’)

library(SimDesign)
Error: package or namespace load failed for ‘SimDesign’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
there is no package called ‘future’

Try running

install.pakcages("future")

and then calling library(SimDesign).
