r - How to install the knitr-module in Lyx 2.0.3? -

-

i installed lyx 2.0.3 on imac , macbook air. when trying open *.lyx document on imac following error-message:

"the module knitr has been requested document has not been found in list of available modules. if installed it, need reconfigure lyx."

on macbook air runs fine without errors.

any ideas how install knitr-module manually?

thanks

the requirement of knitr module in lyx r: have make sure executable rscript in path; can test by:

which rscript

if see path rscript, ready go (tools-->reconfigure); otherwise have tell lyx rscript (add path path prefix):

change path in lyx

then reconfigure lyx.

you can path rscript executing in r:

r.home('bin')
