Cannot install R-forge package using install.packages
Has anyone gotten the latest version of TTR from R-forge working on R 2.13? I can't install it on either my mac or my PC, even if I try compiling from the source.
/edit: here's the exact error I'm getting, when I try to install from the R command line.
install.packages("TTR", repos="http://R-Forge.R-project.org")
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
package ‘TTR’ is not available (for R version 2.13.0)

Yes, sure:

The News says it's now on CRAN. My Mac has 0.20-2 on it and the installer reports that to be the most recent. Loading seems to succeed and no errors from running a few examples.
Re the r-forge version 20-3 I get this:
install.packages("TTR", repos="http://R-Forge.R-project.org") Warning message: In getDependencies(pkgs, dependencies, available, lib) : package ‘TTR’ is not available (for R version 2.13.0 beta)
R version 2.13.0 beta (2011-04-04 r55296) (not the latest)
