2013年1月26日 · rda() will take data frames when called in the rda(X, Y, Z) mode. The arguments in ?rda take about a community data matrix but a data frame is acceptable and even assumed as we convert those inputs via as.matrix() and therein lies the problem.

2017年8月4日 · People ask this sort of thing on the R-help and R-dev list and the usual answer is that the code is the documentation for the .RData file format. So any other implementation in any other language is hard++. I think the only reasonable way is …

2015年10月6日 · I thought that putting an internal dataset for a package into R/sysdata.rda would make the data accessible to my functions. But I can't seem to figure out how to actually access this dataframe. N...

You can create a new environment, load the .rda file into that environment, and retrieve the object from there. However, this does impose some restrictions: either you know what the original name for your object is, or there is only one object saved in the file. This function returns an object loaded from a supplied .rda file.

2011年6月11日 · I want to write code in R which: (1) loads the 'anrdatafile.rda' file; (2) finds the name of the data frame in that file (3) combines the found data frame with another data frame say mydata2. How do I achieve step 2?

I have an rda R file (df) that I want to save as a non binary file (such as txt or csv) so I can use it in a text editor program... Is there a way to do this? Right now using write.csv(df, file=out.csv) or even, saveRDS(df, file=out.rds) gives me an empty file.
