R custom package install from file error

Question

I\'ve been working on a R package for a simulation project, on my computer at home I\'ve used RStudio to build and install it successfully. However on another machine at uni

Answer 1

I found the problem was related to the Windows path backslashes in the roxygen comments in the R script. The solution is to change the backslashes to a single forward slash. Example: originally my roxygen info was like this:

#'  Performs a search in MS Windows file system for all files in the
#'  `C:\USERS\MYNAME` directory, and all directories below that

which results in this warning message:

* installing to library 'C:/Users/MYNAME/Documents/R/win-library/3.2'
* installing *source* package 'whatever' ...
** R
** preparing package for lazy loading
** help
Warning: C:/Users/MYNAME/Documents/R/CODE/whatever/man/func.Rd:11: unknown macro '\USERS'
Warning: C:/Users/MYNAME/Documents/R/CODE/whatever/man/func.Rd:11: unknown macro '\MYNAME'
*** installing help indices
** building package indices
** testing if installed package can be loaded
* DONE (whatever)

The clue is that the text is orange instead of the usual blue in RStudio.

So change the backslash to a forward slash and no warning message is produced and all the roxygen comment is now blue.

#'  Performs a search in MS Windows file system for all files in the
#'  `C:/USERS/MYNAME` directory, and all directories below

I had encountered a similar error a few days ago. It is because you are installing to this directory:

 '\\ueahome5/ressci17/yrq12edu/data/Documents/R/win-library/2.15/speEaR'

I guess it is connected to a network drive. What you should do is go to that network drive and copy the address explicitly like

 'M:/ressci17/yrq12edu/data/Documents/R/win-library/2.15/'

And then use it to specify the library location when you install. For example:

install.packages("speEaR_1.0.tar.gz", repos=NULL, type="source",lib='U:/ressci17/yrq12edu/data/Documents/R/win-library/2.15/')

Or try devtools , unpack your tar ball and do something like:

library(devtools)
has_devel() ## check if your Rtools are properly installed
check('speEaR')
##build('speEaR')
install("speEaR",args='-l "U:/ressci17/yrq12edu/data/Documents/R/win-library/2.15/"')

This is how I solved my problem.
