Dear R Development Team, Using Thomas Baier's R Com Server -- or a dll I am building which supports an evaluate function that is based on Baier's function R_Proxy_evaluate contained in proxy_impl.c -- when I issue an invalid command to R such as "plo(x)" the program crashes. There is code in R_Proxy_evaluate to test for a parse error before actually generating code and issuing the command - He calls R_Parse1Buffer(&lBuffer,0,&lStatus) and then tests the value of lStatus for parse error. The trouble is that lStatus == PARSE_OK even though the command is invalid, so the evaluation continues until eval() is called, at which point R terminates and crashes the program. (It does write an error message to the console first, but crashes after that.) Is there a way to handle this? The same command can be issued inside RGui.exe or RTerm.exe with out a problem. Thankyou, Don Wingate. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-announce mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

"Why did your message get caught by my filter?", you ask... Most
likely it's
because junkmail, unwanted advertising, or harrassing email came from your

Second apologies to the r-help list. I thought I'd disabled this feature and apparently hadn't. I've disabled my procmail filters entirely, as I said I'd do if this recurred.
