Hi,
can you please give a reproducible example and what's your sessionInfo()?
Many years ago when I started to develop the Object class in R.oo,
which is using environments, I also had problems saving environments
directly. I my case I think it was when I added a class attribute to
an environmen
If this is Windows, see shell.exec. On any platform, see browseURL.
Does help.search("url") not get you there?

states--e.g. between Colorado and Utah and between Michigan and Indiana.

Not so in general, so we need the details asked for in the posting guide,
including a reproducible example. (Environments get saved all the time:
they are a fundamental part of R's operations.)

Of course you said when you load it again. I just now loaded it,
without error.

I'm trying to calculate correlation coefficients between corresponding

Hi Erik,
Yes this is what I was trying and your example or the one of luke is working
fine with me.
So now I'm not sure if this is due to an environment which takes too much
space. The environment troubling me has 644276 entries. Is this too much?

If anybody is interested (maybe not :-)): finally I found a workaround:
reinstalling R (in my case building R-devel from source) and then run
update.packages(). But what exactly was the problem remain mystery (for me).
Have a nice day folks

Thanks to Prof. Ripley and Henrique, gsub does do the job. In addition, we can
use like gsub("345","aa", the column of the data frame) to replace all such
characters in this column.
By the way, I am using Windows Vista, R 2.6.1, in Sweden. As for the \\345

I think shell.exec should do what you want:
shell.exec("http://www.yahoo.com";)
