You can try this:
lapply(lapply(ls(pattern = 'DF[0-9]'), get),
'names-', c(SDev,PC1, PC2, PC3, PC4, PC5, PC6))

It seems that the names of original data frames have not changed in
this way. I guess textConnection() could help, like this:
for (name in objects(pattern = df[0-9]))
eval(parse(textConnection(paste('names(', name, ') -
column_names'

Yes, just in the list.
If they want change the name in Environment GlobalEnv:
for(i in ls(pattern = DF[0-9]))
assign(i, `names-`(get(i), c(SDev,PC1, PC2, PC3,
PC4, PC5, PC6)), globalenv())

Amazing! I haven't seen usage of calling `names-` like this before.
Thanks so much!
