Re: [R] object names from character strings
Consider storing the dataframes in a list so that you do not have to create unique names and it will also give you better control by keeping all the data together in one object.

I'm looping through an array, doing various calculations and
producing a resulting data frame in each loop iteration. I need to
give each data frame a different name. Although I can easily create
a new character string for writing each frame to an output file, I
cannot figure out how to convert such strings to corresponding
object names within the R workspace itself, so as to give each d.f.
a distinct name. The closest I got were various attempts with the
as.name function, but couldn't get that to work either. Any help
appreciated. Thanks.
Here's the first example in the help(assign) page:
or(i in 1:6) { #-- Create objects 'r.1', 'r.2', ... 'r.6'
nam <- paste("r",i, sep=".")
assign(nam, 1:i) }
ls(pattern = "^r..$")

[R] object names from character strings
I realize this is probably pretty basic but I can't figure it out. I'm looping through an array, doing various calculations and producing a resulting data frame in each loop iteration. I need to give each data frame a different name. Although I can easily create a new character string for writing each frame to an output file, I cannot figure out how to convert such strings to corresponding object names within the R workspace itself, so as to give each d.f. a distinct name. The closest I got were various attempts with the as.name function, but couldn't get that to work either. Any help appreciated.
