There appears to be a quoting problem in the way R CMD install handles file
names containing spaces, more specifically, in the way the argument is passed
through to gzip.
The install.packages command
(from R)
install.packages("~/Projects/R library/bar/eyetrackR_0.13.tar.gz", repos =
NULL, type = "source")
expands to
system("R_LIBS='/Users/foo/Library/R/2.10/library'
"/Library/Frameworks/R.framework/Resources/bin/R CMD INSTALL -l
'/Users/foo/Library/R/2.10/library' '/Users/foo/Projects/R\
library/bar/eyetrackR_0.13.tar.gz'")
and gives the same error messages as the following commands from Terminal.app
on Mac OS X
(from bash)
R CMD install /Users/foo/Projects/R\ library/bar/eyetrackR_0.13.tar.gz
R CMD install "~/Projects/R library/bar/eyetrackR_0.13.tar.gz"
R CMD install '~/Projects/R library/bar/eyetrackR_0.13.tar.gz'
, namely (the error messages):
gzip: /Users/foo/Projects/R.gz: No such file or directory
gzip: library/bar/eyetrackR_0.13.tar.gz: No such file or directory
The following commands do work
(from R)
setwd("~/Projects/R library/bar/")
install.packages("eyetrackR_0.13.tar.gz", repos = NULL, type = "source")
(from bash)
cd ~/Projects/R\ library/bar/
R CMD install eyetrackR_0.13.tar.gz
Interestingly, if the file is unpacked on the command line (tar xzvf), then
both R CMD install and install.packages work fine using the quoted path name
syntax, i.e.,
R CMD install /Users/foo/Projects/R\ library/bar/eyetrackR
install.packages("~/Projects/R library/bar/eyetrackR", repos = NULL, type =
"source")
Is this a known problem? I searched the archives, but did not find a decisive
answer (only some rather old posts suggesting not to use path names containing
spaces--unfortunately this is not an option in the managed Windows environment
I need to work in next week).
Sorry for the long post and thanks for your time,
Jochen
