Dear all How should I attempt debugging this error? > sosInit() Error: invalid connection
When this happens R refuses to run anything: > 2+2 Error: invalid connection > sessionInfo () Error in stdout() : invalid connection Debugging it seems impossible. > options(error=recover) > sosInit() Error: invalid connection Error during wrapup: invalid connection The error also "crashes" browser(). Browse[1]> n debug at /home/liviu/Devel/Rcmdr-dev/Rcmdr.sos/RcmdrPlugin.sos-0.1-0/R/sosInit.R#51: doItAndPrint(paste("## Launching RSiteSearch, please be patient..")) Browse[2]> Error in function () : invalid connection Error: invalid connection > To reproduce the example, you would need to source the following file [1]. Then require(Rcmdr) require(sos) sosInit() and in the box enter a string similar to "asdf ; HTMLgrid". If you enter simple strings such as "asdf", the function will perform as expected and R will not become non-responsive.
