In wush978/RReadWriteBigDataFrame: Column based write and read list, data.frame and S4 object

Read and Write Big List, Data Frame and S4 Object

• Column-based Serialization
• Faster IO spead due to openmp parallization and comprression

library(RReadWriteBigDataFrame)
n <- 10^8
x <- list(
  numeric(n),
  logical(n),
  raw(n),
  integer(n)
  )
print("saveRDS")
system.time(saveRDS(x, "test1"))
print("Write")
system.time(Write(x, "test2"))
print("readRDS")
system.time(r1 <- readRDS("test1"))
print("Read")
system.time(r2 <- Read(dir_name = "test2"))
all.equal(r1, r2)

• Not support to CharacterVector
