...ast in simple test cases. But is it reliably robust? Are there traps for young players that I am not seeing? My ``solution'' returns NA as the value of fname if bar() is called from the command line, rather than being called by foo() or clyde(). This is acceptable. I think .... Any avuncular advice from those younger and wiser than myself? :-) cheers, Rolf Turner ###################################################################### Attention:\ This e-mail message is privileged and confid...{{dropped:9}}

Dear R-guRus: I would like to pass variables to a function in R in "by reference", e.g Fortran style. For example, suppose I have the following code x<-c(1:10) y<-1 MyFunc<-function(x,y) {y<-sum(x); return(NULL)} MyFunc(x,y) print(y) in this case print(y) will produce "1" instead of 55 (which is sum(x)) - how do I make sure that afte the function is run, y

I'm experiencing a new and annoying phenomenon which seems to consist of an unfortunate interaction between R-1.7.0 and netscape version 7. When I invoke help.start(), a netscape window duly appears with the browser pointed at the file .../R/doc/html/index.html as one would hope and expect. However if I then ask for help on a function, e.g. > help(glm) the help does NOT get displayed
