The "named" data class has been a thorn in my side (and probably everybody
else's) since it was introduced in V.6. I was disappointed that it has not
changed in v.7. That, coupled with several extra bugs and the lack of
response by Insightful to my request to lighten up on the licensing rules,
led me to go back to V. 6.
You have to use "as.numeric" to get rid of the named class before you can
put it in a data frame if you want to avoid that "read-only"
problem. Sure, it is a small thing, but it is very annoying and a frequent
source of error (since nowhere are the rules written about what produces a
named class and what doesn't). Plus it is not mentioned in the
documentation as far as I know.
