安装AWS S3 R包

Question

我正在尝试在R上安装S3包，以便将csv输出保存在我正在运行的回归中。我尝试安装S3包来将Rstudio服务器链接到S3，但没有成功。这是我在尝试安装aws.s3包时收到的错误：

> install.packages("aws.s3", repos = c("cloudyr" = "http://cloudyr.github.io/drat"))

然后我尝试安装httr depence包，但同样没有成功。

is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:

同样，在安装openssl包时也是如此。我的EC2实例类型是t2.media。

Answer 1

在这里，在安装cloudyr的aws.s3包之前，需要一些OS和一些R依赖项。

aws.s3依赖于三个R包：curl、httr和xml。而这些又依赖于libssl、libxml2和libcurl4-openssl OS库。

在一个新的EC2实例上，假设有一个Ubuntu机器(当然，对于Fedora/CentOS/RedHat发行版，有相当的yum包)，必须首先安装操作系统依赖项：

sudo apt-get install -y build-essential libssl-dev libxml2-dev libcurl4-openssl-dev

然后，您可以按指定的顺序安装以下R包：

install.packages('curl')
install.packages('httr')
install.packages('xml2')
install.packages("aws.s3", repos = c("cloudyr" = "http://cloudyr.github.io/drat"))

希望这能有所帮助
