You can install forge from CRAN with

install.packages("forge")

You can install the development version from GitHub with

devtools::install_github("rstudio/forge")

Examples

library(sparklyr)
sc <- spark_connect(master = "local")

spark_vector <- function(sc, x) {
  v <- forge::cast_double_list(x)
  invoke_new(sc, "org.apache.spark.ml.linalg.DenseVector", v)
}

spark_vector(sc, 1:3)
