将软件包安装到R的问题

Question

I tried this:

z <- zscore(NMEBXTP_MeanDepth, na.rm=TRUE)

and got this:

Error: could not find function "zscore"

So I did this:

install.packages(c("R.basic"), contriburl="http://www.braju.com/R/repos/")

And got this:

Warning: unable to access index for repository http://www.braju.com/R/repos/
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
  package ‘R.basic’ is not available

Besides being dysbinarylexic whats my problem?

Answer 1

Did you load the package for use before trying to use it? You need

library("R.basic")

or

require("R.basic")

to actually load the package functions into the running R session for you to be able to use them.

If you don't actually have it installed at all, then something looks amiss with the repository. If we look here we see that R.basic has been deprecated and is not on CRAN. Further, the page tells us that many of the R.basic are in the R.utils and aroma.light packages, both of which are on CRAN. Take a look at the CRAN pages for R.utils and aroma.light to see which one you need for the functionality you wanted to use.

If the problem installing from that repository continues, contact the maintainer of the repository to report the problem.
