First post/newbie post... bear with me. What I''m trying to achive (music site): A system containing tracks and moods with a HABTM relationship. I''ve got all that set up and functioning in the admin environment - i.e. admins can apply a variety of moods to a particular track via a series of checkboxes. Join table works just fine. I''m currently stuck on allowing

Is it possible to toggle the "edit" option of a widget? I would like to make it so that when a user clicks on a boolean (like "use constraints") it will lock or unlock the field in which they would enter the constraints. I can imagine redrawing the whole GUI using a function attached to the boolean, but that's clunky and slow. I tried changing the .PBSmod variable... but

Does anyone know how to pass a list of parameters into a function? for example: somefun=function(x1,x2,x3,x4,x5,x6,x7,x8,x9){ ans=x1+x2+x3+x4+x5+x6+x7+x8+x9 return(ans) } somefun(1,2,3,4,5,6,7,8,9) # I would like this to work: temp=c(x3=3,x4=4,x5=5,x6=6,x7=7,x8=8,x9=9) somefun(x1=1,x2=2,temp) # OR I would like this to work: temp=list(x3=3,x4=4,x5=5,x6=6,x7=7,x8=8,x9=9)

Hello, Anyone knows how can I do this in a cleaner way? mynumber = 1001 as.numeric(unlist(strsplit(as.character(mynumber),""))) [1] 1 0 0 1 Thanks in advance, Gustavo

I thought the "apply" functions are faster than for loops, but my most recent test shows that apply actually takes a significantly longer than a for loop. Am I missing something? It doesn't matter much if I do column wise calculations rather than row wise ## Example of how apply is SLOWER than for loop: #rm(list=ls()) ## DEFINE VARIABLES mu=0.05 ; sigma=0.20 ; dt=.25 ; T=50 ;
