The future3.0
package is a convenience package for those stuck with R versions lower than 2.15 but want the functions introduced in 3.0. If you are using a version of R that is older than 3.0 you would probably want to install the other 'future' packages as well to get the functions provided in those releases of R as well.
This package is incomplete at the moment and not all functions that will be introduced have been ported.
Currently there isn't a release on CRAN.
You can, however, download the zip ball or tar ball, decompress and run R CMD INSTALL
on it, or use the devtools package to install the development version:
## Make sure your current packages are up to date
update.packages()
## devtools is required
library(devtools)
install_github("future3.0", "Dasonk")
# The 'future' package loads the other future packages so you
# don't need to remember to load all of them at once.
install_github("future")
