Hi All:
I tried to update the package mgcv from my current version 1.1-8 to mgcv
version 1.2. Using the command update.packages("mgcv") to update mgcv failed in
my computer and the returning message was:
"Error in old.packages(lib.loc=lib.loc, contriburl=contriburl, method=method,
:no installed.packages for (?invalid) lib.loc=mgcv"
When I typed installed.packages(), I got the following information
libpath = "/usr/local/lib/R/site-library" for the installed package "mgcv".
My next error was when I typed
update.packages("mgcv",lib.loc="/usr/local/lib/R/site-library").
It returned the error message,
"error in download.file(url = paste(contriburl, "PACKAGES", sep="/"),
:unsupported URL scheme"
What should I do to correctly update this package?
I use Debian Linux (MepisLinux), R version 2.0.1
Would greatly appreciate your advice.
TIA,
Arin Basu
