Get specific object from Rdata file

I have a Rdata file containing various objects: New.Rdata |_ Object 1 (e.g. data.frame) |_ Object 2 (e.g. matrix) |_... |_ Object n Of course I can load the data frame with load('New.Rdata') , however, is there a smart way to load only one specific object out of this file and discard the others? .RData files don't have an index (the contents are serialized as one big pairlist). You could hack a way to go through the pairlist and assign only entries you like, but it's not easy since you can't do it at the R level. However, you can simply convert the .RData file into a lazy-load database which

What are the main differences between .RData, .Rda and .Rds files? More specifically: Are there differences in compression etc? When should each type be used? How to convert one type to another? Rda is just a short name for RData. You can just save(), load(), attach(), etc. just like you do with RData. Rds stores a single R object. Yet, beyond that simple explanation, there are several differences from a "standard" storage. Probably this R-manual Link to readRDS() function clarifies such distinctions sufficiently. So, answering your questions: The difference is not about the compression, but

问题 I saw some similar qestions and I tried to work it out on my own, but I couldn\'t. This is my problem: I have to load a isfar.RData file to use it in other computation (which are not important to describe here). And I would like to simply see how looks data in this isfar.RData file e.g. what numbers, columns, rows it carries. First I load my file: isfar<-load(\"C:/Users/isfar.RData\") When I try to obtain this information (I\'m using Rcmdr) by ls() function or marking isfar at the beginning

How can I load an object into a variable name that I specify from an R data file?

问题 When you save a variable in an R data file using save , it is saved under whatever name it had in the session that saved it. When I later go to load it from another session, it is loaded with the same name, which the loading script cannot possibly know. This name could overwrite an existing variable of the same name in the loading session. Is there a way to safely load an object from a data file into a specified variable name without risk of clobbering existing variables? Example: Saving
