Readers,
As root user, from the command:
install.packages()
A dialogue window appears to select packages of interest. What to do if
a specific packages exists on the cran page
(http://cran.r-project.org/web/packages/available_packages_by_name.html),
but not in the dialogue window of a repository?
Sometimes, a dependent package is reported as being un-available, e.g.:
install.packages("mclust")
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
package ‘mclust’ is not available
Alternatively, tried the command 'R CMD':
R CMD INSTALL
http://cran.r-project.org/src/contrib/ChemoSpec_1.61-3.tar.gz
Warning: invalid package
‘http://cran.r-project.org/src/contrib/ChemoSpec_1.61-3.tar.gz’
Error: ERROR: no packages specified
The FAQ web page
(http://cran.r-project.org/doc/FAQ/R-FAQ.html#How-can-add_002don-packages-be-installed_003f)
states that the above syntax should be accepted.
What is my mistake please?
