如何将所有变量从项目导出到.csv，以便随后将其导入Python环境？

Question

I have a large project in RStudio that I would like to attempt some things with in Python and want to know if there is a way of effectively packaging up all of the environment variables (data frames, lists, atomic vectors, etc.) and importing those into Spyder (Python).

If not directly possible, I am aware that I can read files into Python in numerous ways, and as such am wondering if there is a method I could use to iterate through my R environment and save all of the variables as .csv files so that I can later read them into Spyder?

I have tried this code but to no avail:

files <- mget(ls())

for (i in 1:length(files)){
  write.csv(files[[i]], paste(names(files[i]), ".csv", sep = ""))
}

I would recommend looking at some of the packages for transferring data, but to specifically answer your question:

x1 <- "hello"
x2 <- "these are some"
x3 <- "objects"

for (i in names(.GlobalEnv)) {
  write.csv(.GlobalEnv[[i]], file = sprintf("%s.csv", i))
}

You could more explicitly export the objects by storing the objects for export in a separate environment, too.
