[R] Quickie : unload library

[Horace Tso]

Sachin,

I did try that, ex

detach(zoo)

Error in detach(zoo) : invalid name

detach("zoo")

Error in detach("zoo") : invalid name

But zoo has been loaded,

sessionInfo()
Version 2.3.1 (2006-06-01) 
i386-pc-mingw32 

attached base packages:
[1] "methods"   "datasets"  "stats"     "tcltk"     "utils"    
"graphics" 
[7] "grDevices" "base"     

other attached packages:
   tseries   quadprog        zoo       MASS       Rpad 
  "0.10-1"    "1.4-8"    "1.2-0" "7.2-27.1"    "1.1.1" 

Thks,

H.

  Dear list,

I know it must be obvious and I did my homework. (In fact I've
RSiteSearched with keyword "remove AND library" but got timed
out.(why?)....)

How do I unload a library? I don't mean getting ride of it permanently
but just to unload it for the time being.

A related problem : I have some libraries loaded at startup in
.First()
which I have in .Rprofile. Now, I exited R and commented out the lines
in .First(). Next time I launch R the same libraries are loaded again.
I.e. there seems to be a memory of the old .First() somewhere which
refuses to die.

Thanks in adv.

Horace
