替换.Rdata文件中的数据

Question

Is there a way I could replace the table in .Rdata file with another one? I can edit it with edit(x) command, but it would take an enormous amount of time to do this manually; besides, I haven't found a way to add rows to it.

Answer 1

I think you need to read a few 'intro to R' guides.

A .Rdata file is generally a saved session, and can have any number of 'things' saved in it, scalars, vectors, data.frames, lists, functions etc etc. I assume you have a data file that has been read into R into a data.frame and that is saved within a .Rdata file. You can load the .Rdata file with load("....Rdata") then you can 'replace' your table (a data frame), by loading another one over top, if that's what you want to do, so assuming it's called dat, dat <- read.csv("new_data.csv", ...) , and then save the session again, save.image("....Rdata") . I've assumed a lot of things there though...
