Hello,
You can get all objects to be changed into a list, change the list's
names attribute and assign back to the globalenv. Something like the
following.
First see if the objects exist in the global env.
ls()
#[1] "meb1.p.emb" "meb2.p.emb" "mec1.p.emb" "mec2.p.emb"
#[5] "mej12.p.emb" "mej22.p.emb"
Now the code to change their names
# create a vector of names of the objects
# whose names are to be changed
obj_names <- ls(pattern = "\\.emb$")
# this is instruction is not strictly needed
# it's meant to check if the regex works (it does)
sub("\\.emb$", "", obj_names)
#[1] "meb1.p" "meb2.p" "mec1.p" "mec2.p" "mej12.p" "mej22.p"
# get the objects into a list
tmp_list <- mget(obj_names, envir = .GlobalEnv)
# change the list's names
names(tmp_list) <- sub("\\.emb$", "", obj_names)
# assign them to the global environment
list2env(tmp_list, envir = .GlobalEnv)
# clean up
rm(tmp_list)
rm(list = obj_names)
# check to see if it worked (it did)
ls()
#[1] "meb1.p" "meb2.p" "mec1.p" "mec2.p" "mej12.p" "mej22.p"
Hope this helps,

How would I rename these objects removing the silly ".emb", into objects

meb2.p
mej12.p
mej22.p
Thank you!

Re: [R] Renaming multiple objects
Agreed... This Is The Way. To interactively sit at the R console and type in commands without keeping those commands in an editor and running them from scratch periodically to insure that they achieve your goals is a only a recipe for mystery, not for data analysis. R is a tool for transforming raw data into i interpretable forms. If you are not keeping track of how you used it, how can you convince yourself or others that you did it right? And if you are keeping track, then you should feel comfortable editing that set of transformation steps so they do the right thing the first time.
