R help - Jan 2010 - Quantreg - 'could not find function"rq"'

Hi all,

 

I'm having some troubles with the Quantreg package.  I am using R
version 2.10.0, and have downloaded the most recent version of Quantreg
(4.44) and SparseM (0.83 - required package).  However, when I try to
run an analysis (e.g. fit1<-rq(y~x, tau=0.5)) I get an error message
saying that the function "rq" could not be found.  I get the same
message when I try to search for any of the other functions that should
be in the package (e.g. help(anova.rq)).

 

I used this package last year and still have the old versions of both
quantreg and SparseM saved on my machine.  When I load these older
packages and attempt an analysis (which, incidentally, worked fine last
February) I get the same error messages as I do with the new versions.  

 

The only think I have changed since last February is the version of R I
am using - is there any reason why quantreg wouldn't work in version
2.10.0?  I'm not very experienced with R so I'm struggling to work out
what may be going wrong - does anyone have any suggestions!?

 

Many thanks

 

Lauren

Are you sure you called 
library(Quantreg) 
before calling any function?
