Re: [R] saving a 'get' object in R

Greg - I appreciate your taking the time to explain. This is very helpful. My case was a bit unusual as I'm helping a colleague with code to use on a regular but individual basis. I want them to name a data set once at the top of the script and have that name propagate through several objects

Re: [R] saving a 'get' object in R

Seems to me you are creating your own troubles in your requirements. If the analysis is the same from case to case, it makes more sense to use a single set of object names within the analysis and change only the names of the input and output files.

[R] saving a 'get' object in R

R community, Apologies if this has been answered. The concept I'm looking for is to save() an object retrieved using get() for an object that resulted from using assign. Something like save(get(foo),file=paste(foo,'rData',sep='')) where assign(foo,obj) creates an object named foo with the

Re: [R] saving a 'get' object in R

You can use the following command: tmp - get(foo) save(tmp,file=paste(foo,'.rData',sep='')) Best, Mike 2014-06-24 15:35 GMT-05:00 David Stevens david.stev...@usu.edu: R community, Apologies if this has been answered. The concept I'm looking for is to save() an object retrieved using

Re: [R] saving a 'get' object in R

I think that you are looking for the `list` argument in `save`. save( list=foo, file=paste0(foo, '.Rdata') ) In general it is best to avoid using the assign function (and get when possible). Usually there are better alternatives. On Tue, Jun 24, 2014 at 2:35 PM, David Stevens

Re: [R] saving a 'get' object in R

I recommend to use saveRDS()/readRDS() instead. More convenient and avoids the risk that load() has of overwriting existing variables with the same name. /Henrik On Tue, Jun 24, 2014 at 1:45 PM, Greg Snow 538...@gmail.com wrote: I think that you are looking for the `list` argument in `save`.

Re: [R] saving a 'get' object in R

Thanks to all for the replies. I tried all three and they work great. I was misinterpreting the list = parameter in save(...) and I get your point about overwriting existing objects. I've heard about not using assign/get before. Can anyone point me to why and what alternatives there are?

Re: [R] saving a 'get' object in R

The main reason to avoid assign/get is that there are better ways. You can use a list or environment more directly without using assign/get. Also the main reason to use assign/get is to work with global variables which are frowned on in general programming (and prone to hard to find bugs).
