If your package has dependencies, you have three fields you can specify them in:
Depends, Imports, and Suggests.4 With Depends, you can specify both packages
that need to be installed for your package to work and which version of R is
required for your package to work. For packages, though, it is better to use
Imports and Suggests than Depends, so use Depends only to specify which
version of Ryou need. You specify it this like: Depends: R (>= 2.10) This is saying
that you need ...

the magnitude of the difference cannot be measured. Furthermore, when
importing data into R, we often run into the situation where a column of numeric
data might contain an entry that is non-numeric. In this case, R might import the
column of data as factors, which is often not what was intended by the data

Given the organization and volume of files, we cannot simply read the files into R
by writing calls such as readLines("messages/easy_ham/00006.3
ca1f399ccda5d897fecb8c57...") How do we read the contents of the files into R in
a more general, automated, machineindependent manner? And, is readLines()
the function we should use? Let's address the second question first. The manual,
R Data Import/Export [3] describes several functions available to us in R for
reading input from ...
