R上云也很容易-cloudyr项目

cloudyr项目目的旨在建立起R语言与云交互的接口，目前实现了aws大部分交互功能。像Google Cloud Services和Microsoft Azure也被列入计划，是一个值得期待的计划。

# 安装cloudyr生态下的R包，首先先添加源，方式如下：
if (!require("drat")) {
    install.packages("drat")
}
drat::addRepo("cloudyr", "http://cloudyr.github.io/drat")
install.packages("XXXXX")
# 每次安装cloudyr包，都需要执行上面的操作，为了方便可以添加
# drat::addRepo("cloudyr", "http://cloudyr.github.io/drat") 到
# .Rprofile或者Rprofile.site文件中

下面以aws.s3为例：

# 需要提前配置aws认证
library("aws.s3")

# 配置Key
Sys.setenv("AWS_ACCESS_KEY_ID" = "mykey",
           "AWS_SECRET_ACCESS_KEY" = "mysecretkey")

# 查看S3仓库列表
bucketlist()

# 获取某个具体的仓库
get_bucket(bucket = '1000genomes')

# 保存文件至本地
save_object("mtcars.Rdata", file = "mtcars.Rdata", bucket = "my_bucket")

# 上传文件到S3
put_object(file = "mtcars.Rdata", object = "mtcars2.Rdata", bucket = "my_bucket")

基本上和官方boto3类似，实现了大部分的接口，虽然有小部分功能还待完善，但是总体来说是一个好的开始。
