[程式范例]:
require(data.table) # v1.9.7
require(feather) # v0.0.0.9000
require(readr) # v0.2.2
DTn = function(N) data.table(
str1=sample(sprintf(“%010d”,sample(N,1e5,replace=TRUE)), N, replace=TRUE),
str2=sample(sprintf(“%09d”,sample(N,1e5,replace=TRUE)), N, replace=TRUE),
str3=sample(sapply(sample(2:30, 100, TRUE), function(n)
paste0(sample(LETTERS, n, TRUE), collapse=””)), N, TRUE),
str4=sprintf(“%05d”,sample(sample(1e5,50),N,TRUE)),
num1=sample(round(rnorm(1e6,mean=6.5,sd=15),2), N, replace=TRUE),
num2=sample(round(rnorm(1e6,mean=6.5,sd=15),10), N, replace=TRUE),
str5=sample(c(“Y”,”N”),N,TRUE),
str6=sample(c(“M”,”F”),N,TRUE),
int1=sample(ceiling(rexp(1e6)), N, replace=TRUE),
int2=sample(N,N,replace=TRUE)-N/2
)
set.seed(21)
DT = DTn(1e6)
Either ram disk :
setwd(“/dev/shm”)
or HDD/SDD :
setwd(“~”)
system.time(fwrite(DT,”fwrite.csv”))
