My sense is that even if this were possible (which I doubt), it would be outside the scope of what would be considered appropriate in R (assuming I understand the question). After all, it's someone else's package, theirs to control and maintain, etc. What if it's an installation of R on a multi-user platform, and other users might use the same package but not want the modified data?
I would likely save the modified data frame with a slightly different name, arrange some way to make it easily available, and then just use it, rather than the original. There are various ways to make it readily available. If I always wanted the data to be available when I load the package, what I might do is download the source package, make a copy of it, modify the data object in the copy, rename the package (slightly), then build and install it. Then I would just load the modified package instead of the original. -Don -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On 2/4/13 11:37 AM, "Rich Shepard" <rshep...@appl-ecosys.com> wrote: > The bio.infer package contains a data frame >/usr/lib/R/library/bio.infer/data/itis.ttable.rda that needs to be >modified. >After loading the bio.infer package and attaching the data frame with the >data() function, I wrote the data frame to a text file. > > After adding another row to the data frame I applied read.table() to >create a data frame, but it's in my pwd, not the R library data >subdirectory >for the bio.infer package. > > What is the R function to copy/save/write either the text file or the >local copy of itis.ttable to >/usr/lib/R/library/bio.infer/data/itis.ttable.rda? > >Thanks, > >Rich > >______________________________________________ >R-help@r-project.org mailing list >https://stat.ethz.ch/mailman/listinfo/r-help >PLEASE do read the posting guide >http://www.R-project.org/posting-guide.html >and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
