在R中保存数据文件 [英] saving a data file in R

问题描述

我已成功将.txt文件加载到R中.我想保存数据，以便可以实际使用它.保存文件的命令是什么?我是将文件保存到现有软件包之一(UsingR，MASS)中，还是将其保存为单独的文件?

I have successfully loaded a .txt file into R. I want to save the data so I can actually actively use it. What is the command for saving a file? Will I save the file to one of the existing packages (UsingR, MASS), or just as a separate file?

推荐答案

您要查找的命令是以下任一命令:

The command you look for is either one of these :

• save():将提到的对象另存为R个对象(扩展名.RData).这些文件是二进制文件，可以使用load()
再次快速读取.
• write():是cat()的包装，用于从对象(通常是矩阵)创建文本文件.
• write.table()和write.csv():是用于使用特定分隔符将数据帧写为文本文件的命令.

• save() : saves the mentioned objects as R objects (extension .RData). These files are binary and can be read very quickly again with load()
• write() : is a wrapper for cat() and is used to create text files from objects, usually matrices.
• write.table() and write.csv() : are commands to write data frames as text files with a specific separator.

还请检查sink()，用于将其他输出重定向到文件(通常用于记录目的).

Check also sink(), used to redirect other output to a file (usually used for logging purposes).

请阅读R的手册:
