The following will work, but I would suggest that you redesign your functions so that they do not use 'globals'; It is not nice for functions to have side-effects.
g_Means<-numeric() defineSamples<- function() { g_Means <<-5 # check out ?"<<-" } runit<-function() { defineSamples() g_Means #####<<This returns "numeric(0)", and not "5" } runit() A better way might be: no side effects defineSamples<- function() { 5 } runit<-function() { defineSamples() } runit() On 4/1/07, projection83 <[EMAIL PROTECTED]> wrote: > > > My R code has got too complex to have a non-modular approach.
