[R] how can i see all the .Rdata files within R

[jia ding]

For example, I saved several .Rdata files with different names:
a.Rdata, b.Rdata ...  But, if I forget the specific file name, how can
I get all files list?

One more question about .R file:

> source("~/Desktop/allchapters.R",local=FALSE)
Error in parse(file, n = -1, NULL, "?") : syntax error at
135: names(airquality)
136: [

why?
