Are you sure you called

M.
Are you both using a package with the exact spelling "Quantreg"? I
would have expected it to be :
library(quantreg)

Subject: [R] 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
