Re: [R] Include files?
Several solutions, easiest might be to use the source function in your program. Also, you could create a .Rprofile if you use them every time you use R.

Re: [R] Include files?
Thanks. I think source is what I was looking for.

If you are running a Unix based machine, rolling your own package is a snap.
Just load the R file containing your functions:
source('myFunctions.R')
Then use the package.skeleton to create an R package from the functions you
just loaded:
package.skeletion('myPackage')
package.skeleton will place just about every R object you currently have in
your environment into your package- this is a great way to save datasets
along with the functions you use to manipulate them.
Now comes the part that can be difficult on Windows. package.skeleton
created a directory called 'myPackage' that needs to be packed up into an
archive and then installed. This can be done from within R by the following
two commands (it may also be done directly from a command line, just execute
the commands inside the quotes ' ' ):
system( 'R CMD build myPackage' )
system( 'R CMD INSTALL myPackage' )
After that you can load up all your functions using:
library(myPackage)
After your package is loaded, if you had a data.frame or other variable
named myData when you created the package, you can load it up using:
data(myData)
The difficulties that arise on Windows are due to the poor state of the
Windows command line when it comes to the tools that are necessary to build
the package- most importantly you need a Perl interpreter. Duncan Murdoch
has put together an installer that can supply the missing tools- you can
find it at:
http://www.murdoch-sutherland.com/Rtools/
If it asks anything about modifying your PATH while installing, allow it to
do so. Placing a folder of tools in the PATH makes the difference between
using
perl myScript.pl
or
/really/long/tiresome/hard/to/remember/path/to/perl myScript.pl
...or just using source works as well! ;)
