David, Thank you. You are correct - I was inadvertently accessing an old version. Deleting the old and re-installing means I can fire up R V3.0.1 which runs fine.
However, I still can't get R Studio to start up, receivng the following message: ERROR r error 4 (R code execution error) [errormsg=Error in identical(call[[1L]], quote(doTryCatch)) : 7 arguments passed to .Internal(identical) which requires 5 , code=local(source("/Applications/RStudio.app/Contents/Resources/R/Tools.R", local=TRUE, echo=FALSE, verbose=FALSE, encoding='UTF-8'))]; OCCURRED AT: core::Error r::exec::<anonymous namespace>::evaluateExpressions(SEXP, SEXP, SEXP *, sexp::Protect *) /Users/rstudio/rstudio/src/cpp/r/RExec.cpp:145 Even though I re-installed the latest version 0.97.551. I wonder if there is an old Library or other support file that was not properly replaced?
