[R-SIG-Mac] “pdflatex is not available” from “R CMD check”

[Spencer Graves]

Hello:  


	  What should I do to diagnose and fix “pdflatex is not available” from “R CMD check” on a Mac running OS X 10.10.1 (see below for more details including sessionInfo.)?  


	  A blog on "Building R packages: missing path to pdflatex” (http://www.r-bloggers.com/building-r-packages-missing-path-to-pdflatex/ <http://www.r-bloggers.com/building-r-packages-missing-path-to-pdflatex/>) suggested the following:  


Sys.which("pdflatex”) 
# "" 
Sys.getenv("PATH")
# [1] "/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin”


	  However, the suggested fix did not work for me.  


		    1.  How can I determine if pdflatex is installed?  


		    2.  If it is, how can I find it?  If it’s not, what i the recommended install procedure?  


	  Thanks 
	  Spencer Graves

Hmm ... looks like a package

You may want to clean up by 'rm -rf /var/folders/mh/mrm_14nx19g13lsnj9zmvwjr0000gn/T//RtmpjOTCtB/Rd2pdf1651fa89c1’
